Quick Test Professional
I) Basic features of QTP
o
QTP Launched in 2002 (Nov). By Mercury Interactive. Later taken
over by HP, in 2007.
o
QTP is an Object Based Testing Tool.
o
QTP is for functional and Regression Testing.
o
It follows Keyword driven approach.
o
It supports Windows Operating Environment only.
o
It supports GUI based (Graphical user interface) and Web based
Applications Automation, does not support CUI (Command user interface)
Applications.
o
It has multilingual support. (It supports English, Chinese,
Japanese, Korean, etc languages with respect to license.)
o
It has adapted Microsoft Visual Basic Scripting edition for
programming and excel like spread sheet for Data driven testing.
o
SQL (Structured query language) embedded or inserted with QTP, so
we can use SQL statements directly from QTP.
o
It can be integrated with other Tools like WinRunner and Quality Center.
o
It can be used for user interface (UI) test case automation and
some limited (Non UI) Test case automation like File system operations and Data
base operations.
o
It was derived from Astra QuickTest (mother tool of QTP).
o
It supports IE (Internet Explorer) only for recording tests, for
execution it supports other browsers like Mozilla and AOL, opera Etc apart from
IE.
o
QTP is a Desktop Application (I-Tier/Stand alone).
o
QTP has two types of License,
1. Seat or Node locked License,
2. Concurrent or float license.
Seat license for one system and Concurrent License, we can use for
any system but one user at any time. If we want multiple concurrent licenses we
can purchase.
o
QTP has UNI code support.

Key Elements of QTP Tool Window

QTP Tool Window
1) Test
Pane:
It is programming interface of QTP, used for creating, editing,
viewing and deleting test scripts.
Test: It is
a set of statements or set of one or more actions. (It is a local concept)
Action: It is
a set of Statements. (It is a local concept)
Statement: A
minimal executable unit. Statements may have keywords. (Keyword such as
function, method, statement etc). It is a global concept.
Test pane has 2 views.
Expert
view- Test in VB script format.

QTP Test Pane-Expert View
Key
word view- Test in Icon based GUI format.

QTP Test Pane-Keyword View
Note1: Here in test pane Test is same but views are different, if
you perform any modifications in one view those automatically reflects in
another view.
Note 2: Technical users use expert view and business user use key
word view.
Note 3: User can customize Test pane view options.
Navigation: Tools Menu> view options> we can use font size
and colors etc.
2) Active Screen
It has an optional element of
QTP, it takes snap shots of every statement that user performed action or
operation on AUT.
It can be used for understanding and editing the test easily.
Navigation: View menu>active screen (for launching and closing)
Configuring active screen: view>options>active screen
tab>increase /Decrease capture level, apply and okay.
Note 1: Generally novice testers use this feature but it occupies
lot of memory space on QTP.

Active Screen
3) Data Table
It has an integrated spread sheet (Excel like), used for Data
driven testing.
Navigation: View menu>Data table (for launching and closing)
Data driven Testing: Testing the same task(S) or same operation
with multiple sets of test data.
It can be used in two ways.
- Enter test data directly into Data Table and use.
- Importing data from external files (Flat files, excel sheets, etc) and Data bases (MS access, Sql Server, oracle, etc.)
It has two types of sheets.
- Global Sheet- for entire test /used for all actions in the test.
- Action Sheets- for specific action only.
Data table available in 2 ways:
- Design time data table. (Attached with every test)
- Run time data table. (Available in result window)
Run time is a carbon copy of design time data table.
QTP has Data table methods for performing operations on data
table.

QTP Tool window- Data Table
4) Debug Viewer
It is used for locating and rectifying or fixing errors.
It can be used for debugging the tests by step-by-step execution.
We use step into, step over and step out commands for debugging.
(debug commands)
Through Debug viewer user can watch variables and change values of
variables temporarily.
Navigation: View menu>debug viewer (for launching and closing)

Analyzing the AUT
Before we begin creating a test, we need to analyze our
application and determine our testing needs.
First, determine the
development environments in which our application controls were developed, such
as Web, Java, or .NET, so that we can load the required QuickTest add-ins.
Then determine the
functionality that we want to test. To do this, consider the various activities
that customers perform in our application to accomplish specific tasks. Which
objects and operations are relevant for the set of business processes that need
to be tested? Which operations require customized keywords to provide
additional functionality?
While we are thinking
about the business processes we want to test, consider how we can divide these
processes into smaller units, which will be represented by our test's actions.
Each action should emulate an activity that a customer might perform when using
your application.
As we plan, try to
keep the amount of steps we plan to include in each action to a minimum.
Creating small, modular actions helps make our tests easier to read, follow,
and maintain.
Recording and Running:
In QTP there are 3 recording modes available for preparing Tests.
1.
Normal Recording
It records User Mouse and Keyboard operations on AUT with respect
to objects, but unable to record continuous mouse operations like Digital
Signatures, graphs, paints etc.
During recording QTP generates VbScript statements in Test Pane,
Simultaneously it stores objects information into object repository.
Navigation: Automation>Record
Or
Select Record option on automation toolbar
Or
Use short cut key (F3)
Steps for preparing a Test (through
Recording):
- Put AUT in base state
- Select Record Option
- It shows Record and Run Settings, Select type of Environment (Windows or Web)
- Select Record Option
(It shows two Options :
- Record and Run Test on any open window based applications
- Record and Run only on
If we select first option it
records on any opened application on Desktop.
If we select Second option, it
asks for the path of the AUT, After Providing the path it records only on that
particular application.)
- Click OK
- Perform actions on AUT
- Stop recording.
- Save the Test
2.
Analog Recording:
It records the exact mouse and keyboard operations. We can use
this mode for recording continuous mouse operations. It is not useful for
recording normal operations why because it does not generate steps for each
operation, generates total user actions in a Track File. The Track file is not
editable.
Navigation:
- Keep tool under recording mode
- Automation >Analog Recording
OR
Use Short cut Key (Shift +
ALT+F3)
Steps for preparing a TEST (through
Analog Recording):
- Launch AUT (or we can launch AUT through QTP)
- Select Record option
- Automation>Analog Recording
- Analog Recording Settings Dialog box opens
(In this Dialog box two options
available.
- Record relative to the screen
- Record relative to the following window
If we select first option QTP
records User operations with respect to Desktop co-ordinates.
If we select Second option, we have to show the window (AUT),
after showing the Window it records with respect to that window co-ordinates.)
- Select any one option in the dialog box and click Start Analog record.
- It records User actions
- Stop Recording
3. Low Level Recording
It records some operations on
Non-supported environments apart from Normal
operations.
This mode records at the object level
and records all run time objects as window or winobject Test objects.
Use Low Level Recording for recording in
an environment not recognized by QTP.
Navigation:
- Keep tool under recording mode
- Automation >Low Level Recording
Steps for preparing a TEST (through Low
Level Recording):
1)
Launch AUT (or we can launch AUT through
QTP)
2)
Select Record option
3)
Automation> Low Level Recording
4)
Perform options on AUT
5)
Stop Recording
6)
Save the Test
Object
Repository
Object Repository:
It is a storage place of QTP where we can store the objects information and it also acts as interface between the test script and the AUT in order to identify the objects during execution.
Object:
Object is something, which has structure and properties.
Software objects:
We call windows, WebPages, buttons, edit boxes, check boxes etc..
as software objects.
Types of Object in QTP:
There are four types of object available
in QTP.
- Run time objects
- Test objects
- Utility objects
- Automation objects/User defined objects.
Run time objects: The
objects present in the AUT. Ex: Buttons, links, etc…
Test Objects: References of
Run time objects. Ex: WinEdit, WinButton, WebButton, Link, etc…
Note:
Test
objects names vary from one environment to another.
Ex:
Run time objects
|
Test objects in windows Environment
|
Test objects in VB
Environment
|
Test objects in web Environment
|
buttons
|
WinButton
|
VBButton
|
WebButton
|
Edit box
|
WinEdit
|
VBEdit
|
WebEdit
|
Check box
|
Wincheckbox
|
Vbcheckbox
|
Webcheckbox
|
Utility objects
They
are QTP reserved objects used for testing and result reporting.
Ex:
1.
SystemUtil for launching/closing the application.
2.
Reporter for defining results.
3.
Services for inserting transaction points
4.
Environment for using environment variables
Automation objects/User defined objects
User can create objects; those can be
used for performing specific operations. Ex: Creating objects in file system
object class, adodb.connection class, dictionary object class, excel.
Application class etc.
There are two types of repository
available in QTP.
- Local repository (.MTR extension)
- Shared repository(.TSR extension)
Local Repository:
QTP creates a Local Repository for every
action automatically during Recording. That cannot be shared among tests.
User
can add some more objects to Local repository
User
can perform rename, delete operations in local repository. As it is QTP
internal file user no need to save modifications.
Navigation:
Resource menu>object repository (Short cut key Ctrl+R)

QTP-
Local Repository
Shared Repository:
User (Test Engineer) creates shared
repository by adding objects. That can be shared among number of tests.
Using this method user can perform
modifications on objects easily.
Operations on Object Repository
Adding objects
a. Local Repository:
Navigation:
open local repository (resource menu>object repository)
>objects>Add
objects to Local>show the object>click ok
(No
need to save separately, it saves automatically)
B. Shared Repository:
Navigation:
Resource menu>object repository manager>object>Add objects>show the
window/object>click ok
o Selected object only
o Default object types
o All objects types
o Selected object types
(If we select first option it stores
Selected objects only, if we select second option it stores all default
objects, if we select third option it stores All objects including static
objects, if we select fourth option, we have to select object classes then it
stores that class objects, we can select more than one class also.)
Renaming objects
a. Local Repository:
Resources > object repository
>select object and right click >choose rename option >modify the
name>release the mouse.>close repository
b. Shared Repository:
Resources >object repository manager>file>open>browse
path of the repository file >file>enable editing>select object
&Right click>choose rename option>modify the name > release
mouse>save the file & close repository manager.
Deleting objects
a. Local Repository:
Resources > object repository
>select object and right click >choose delete option >confirm
deletion>. >close repository
b. Shared Repository:
Resources >object repository
manager>file>open>browse path of the repository file
>file>enable editing>select object &Right click>choose delete
option>confirm the deletion >save the file & close repository
manager.
Associating objects repositories to an action
Resources>Associate
repositories>click add icon (+)>browse path of the
repository>Associate with an action>click ok
Merging Repositories
Resources > object repository
manager>tools>object repository merge tool >browse path of the first
repository> browse path of the second repository>click ok>click
close>save the merged repository>close the repository manager.
Note: After merging also, source
repository files will be available, if we do not want source files we can
delete.
Defining new test objects
Navigation: Object>Define new test
object >Select Environment>Select Class of the object>Enter name of
the object>Click Add>click close>Select object >select property
name>enter value (like this select one by one properties and enter
values)>save
Note: This feature can be used for
preparing tests before the AUT is ready.
Spying objects
For getting objects information, (Test
objects names, property & Values) QTP is providing a feature called Object
Spy, using this we can get objects information.
Navigation>Tools>object
spy>take hand icon & Show the object>get information (Object Spy
shows the specific objects all available properties with their values)
Note: As Object spy is an important
feature, it can be available in 3 Areas.(1. In tools Menu 2. In local
repository 3. In Repository manager)
View Options
Locate in Repository
This
feature can be used for identifying objects from application to repository.
Navigation:
View>Locate in repository >show the object>click Ok>it locates
specified object in the repository.
Highlight in Application
This
feature can be used for identifying objects from repository to application.
Navigation:
Select object in the repository >view>highlight in application>it
highlights specified objects in the application.
Exporting Repository to an XML file
We can export our repository file to an
xml file.
Navigation: File >export Test objects
to XML Enter the file name and Save with xml extension.
Importing Repository from XML file
We can import XML file to our
repository.
Navigation: File>import from XML
>browse path of the XML file >it loads objects.
Note: The purpose of this feature is Editing
objects information outside of the QTP
Descriptive Programming
Entering / Providing objects information directly into the test
script is called Descriptive Programming.
In this method of script creation, we no need to have Object
Repositories.
Advantages:
a) Descriptive Programming based Test scripts are faster in
execution than Repository based Test scripts.
b) Scripts are portable (we can run these scripts from any machine
easily)
c) Maintenance is easy (less amount of resources)
d) We can start Test Execution process even though Application is
not ready.
Descriptive programming is basically 2 types.
- Static Programming
- Dynamic Programming
Static
Programming
In this style of script generation, we provide objects information
directly into the script.
Ex:
Invokeapplication
"C:\Program Files\HP\QuickTest
Professional\samples\flight\app\flight4a.exe"
dialog("text:=Login").Activate
dialog("text:=Login").Winedit("attached
text:=Agent Name:").Set "asdf"
dialog("text:=Login").Winedit("attached
text:=Password:").Set "mercury"
dialog("text:=Login").Winbutton("text:=OK","width:=60").Click
Note:
- Dialog, WinEdit and WinButton – Test Objects
- text, attached text - Property names
- Login, Agent Name:, Password:, OK - Property values or Logical Names of the Object
- Activate, Set, Setsecure, Click - Methods
Note2:
If we feel one property information is not sufficient for
recognizing the object uniquely, then we can provide more properties
information by separating with commas.
Note 3:
If we want to get objects information (Test objects, properties
and values), we can use object spy feature. This feature is available in Tools
Menu, in local repository and in repository manager.
-------------------------------------------------------------------
If we want maintain ‘Objects
information’ in centralized location then we can use Constants.
Steps:
Creating
Constants:
Const Login="text:=Login",
Agent="attached text:=Agent Name:"
Const Pwd ="attached
text:=Password:", Ok="text:=OK"
Note: we can declare no of Constants in a line by separating with
Camas (,), if we take other line then we have to use Const Statement again.
Creating
a Library file
Place Constants in Notepad and save as .vbs file
Associate the Library file to QTP (File->Settings->Resources->
Click add (+) icon-> Browse path of the Library file->Click Apply and
click Ok buttons
Otherwise, we can load the library file during run-time
Syntax:
ExecuteFile “Path of the Library file(.vbs)”
After that create the Test Script using Constants
Creating
the Test Script using Constants:
Invokeapplication
"C:\Program Files\HP\QuickTest
Professional\samples\flight\app\flight4a.exe"
Dialog(Login).Activate
Dialog(Login).Winedit(Agent).Set
"asdf"
Dialog(Login).Winedit(Pwd").Set
"mercury"
Dialog(Login).Winbutton(Ok).Click
Advantages:
If we maintain Object Information in the centralized location,
then we can handle modifications easily.
-------------------------------------------------------------------
Dynamic
Programming
In this style of script generation, first we create description
objects, provide properties information and use description objects in the test
script.
Creating
Properties Collection Objects
Set oLogin=description.Create
Set oAgent=description.Create
Set oPassword=description.Create
Set oOk=description.Create
Entering
Properties Information into Objects
oLogin("text").value="Login"
oLogin("width").value=320
oLogin("height").value=204
oAgent("attached text").value="Agent Name:"
oPassword("attached text").value="Password:"
oOk("text").value="OK"
Generating
Tests using Properties collection Objects
Invokeapplication "C:\Program Files\HP\QuickTest
Professional\samples\flight\app\flight4a.exe"
Dialog(oLogin).Activate
Dialog(oLogin).Winedit(oAgent).Set "asdf"
Dialog(oLogin).Winedit(oPassword).Set "mercury"
Dialog(oLogin).Winbutton(oOK).Click
Note1: Create Description objects and put into one library file,
by associating that library file, we can generate tests.
Note2: Dynamic programming is some difficult in preparation than static
programming but maintenance is very easy.
----------------------------------------------------
In
this style of script creation also, we can maintain Objects information in the
Centralized location by putting collection objects in a Library file.
----------------------------------------------------

Enhancing Tests
After generating the basic test, we have to enhance the test in
order to Test the AUT with respect to requirements.
There are several methods available in QTP for enhancing the TEST.
1.
Inserting Check Points
2.
Inserting Output Values
3.
Adding Comments
4.
Inserting Flow Control Statements
5.
Synchronization
6.
Parameterization
7.
Generating Steps through Step Generator
8.
Inserting Transaction Points:(Start and End)
Inserting Checkpoints
Check point is a verification
point, it takes expected result from the user and compares with actual results
during execution and provides test results.
There are
11 Checkpoints available in QTP:
1.
Standard check point
2.
Text check point
3.
Text area check point
4.
Bit map check point
5.
Data base check point
6.
Accessibility check point
7.
XML Check point (from Application)
8.
XML Check point (from Resource)
9.
Page check point
10. Image checkpoint
11. Table checkpoint
Note 1: From 6 to 11
checkpoints are only for Web.
Note 2:
From 9 to 11 checkpoints are hidden checkpoints, we can insert these
checkpoints through standard checkpoint.
1.
Standard Checkpoint:
It
checks object property values. We can use this checkpoint for checking any
property value.
Navigation for Inserting standard checkpoint
Keep
tool under recording mode > place cursor in desired location > Insert >
check point > Standard checkpoint > Show the object > click okay > select property and
enter expected results & click Ok and stop Recording.
Navigation for Editing standard checkpoint
Select Checkpoint
statement and right click > choose checkpoint properties option > modify
the value > click Ok.
Navigation for Deleting standard checkpoint:
Select Checkpoint
statements and right click > choose delete option.
Inserting Standard check points through
active screen:
View >
Active Screen >place cursor in desired location >Place mouse pointer on
active screen & right click> choose insert standard checkpoint option >
click ok > enter expected result > click ok
Note:
Inserting Standard check points through keyword view same as in expert view.
Note: We can insert standard
checkpoints in 3 ways.
1. Through
expert view,
2. Through
keyword view,
3. Through
Active screen.
2) Text Checkpoint:
It Checks object’s text property value in
different ways.
Navigation:
Keep tool under Recording mode >Insert
menu > checkpoint > Text checkpoint > Show the object > click ok >
Select options
(Match case; ignore spaces, exact match, text not
displayed.)
We can
select one or more options > click ok & stop Recording.
3) Text Area Checkpoint:
It checks the text area present
in the application.
Navigation:
Keep tool under Recording mode
> Insert menu> Checkpoint > Text area checkpoint > Mark the area of
text > select one or more options
(Match case, ignore spaces, exact match, text not
displayed.)
Click
ok and stop recording.
4. Bitmap checkpoint:
It compares bitmaps; we can
compare complete bitmaps as well as part of the bitmaps.
Navigation:
Keep tool under Recording mode >
Insert menu > Checkpoint > Bitmap checkpoint > show the Bitmap >click
ok >select “check only selected area” option if we want to compare part of the
bitmap > click ok >stop recording.
5. Database checkpoint:
It checks Content of the back
end Database.
Navigation:
Insert > checkpoint > Database
checkpoint >choose “specify SQL statement manually” option >click next
> click create > select machine data source > Select DSN (QT_flight32)
> click ok > enter SQL statement (select * from orders) > finish > click
ok.
Note: here we do not need to put tool under Recording mode and we do not
need AUT since data is from backend.
6.
Accessibility check
point:
It checks whether the webpage
in our web application is developed according to W3C (World Wide Web
consortium) Rules and Regulations or not.
It is a
configurable checkpoint, according to our requirements, we can customize.
Configuring accessibility checkpoint:
Tools
menu> options >web > advanced > check/uncheck items > click
apply > click ok
Invigilation:
Keep
tool under recording mode with web environment
>insert>checkpoint>accessibility checkpoint>show the
webpage>click ok>click ok>stop recording.
Result
Criteria:
a) If item
is available but not according to W3C rules then fail.
b) If an
item is available, according to W3C rules then Pass.
c) If an
item is not available then result would be pass
7. XML
Check point (from Application)
It checks content of the XML
file.
Navigation:
Keep tool under Recording mode
in web environment > insert menu > checkpoint (from application)> show
the xml pages >click ok > stop Recording.
8. XML
Check point (from Resource)
It checks content of the XML
file.
Navigation: Insert menu > checkpoint
>xml checkpoint (from resource) > browse path of the XML File > click
ok > click ok.
Note: 1. If XML file is an
individual and path available, and then we can go for inserting xml checkpoint
from resource.
Note: 2. If XML file is part of
web application, separate path is not available then we can choose inserting
XML checkpoints from application.
- Page checkpoint:
It checks number of Links, Images
and Loading time in a web page.
It is a hidden checkpoint; we
can insert this through standard checkpoint.
Navigation:
Keep tool under Recording mode
with web environment > Insert menu > checkpoint > Standard checkpoint >show
the web page > click ok > click ok > stop recording.
10.Image
checkpoint:
It checks Image property
values.
Navigation:
Keep tool under Recording mode with web
environment > Insert menu > checkpoint >standard checkpoint > show
the image > select image > click ok > click ok >stop recording.
11.Table
checkpoint:
It checks content of the web
tables.
Navigation: Keep tool under Recording
mode under web environment > Insert menu > checkpoint > standard
checkpoint >show the web table > click ok >stop recording.
Inserting Output Values
It is a step in which one or
more values are captured during test execution.
The values can later be used as
input at a different point in the run session or we can use as input for
another test.
It is stored in run time data
table; it is located in QTP result window and can be retrieved later.
Types of Output Values:
1. Standard
output value
2. Text
output value
3. Text
area output value
4. Database
output value
5. XML
output value (From Application)
6. XML
output value (From Resource)
1) Standard
output value:
We can use standard output values to output
the properties values of most objects.
Navigation:
Keep tool under Recording mode
> Insert menu >output value> standard output value > show the
object > click ok > select property > modify the column name (if
required) > click ok >click ok >stop recording.
2) Text
output value:
We can use Text output values
to output text strings displayed in an application. When creating a text output
value we can output a part of the objects text and we can also specify text
before and after options.
Navigation:
Keep tool under recording
mode> Insert menu> output value > text output value > show the text
>select one of the option(output text/text before/text after) > click
modify if you want to change the column name > click ok > click ok.> check
in runtime table after running it.
3) Text Area
output value:
We can use text area output
values to output text strings displayed within a defined area of the screen.
Navigation:
Keep tool under recording mode >
insert menu >output value > text area output value >Mark the text area
>click modify the column name if necessary > click ok > again click ok
> check in run time table after running it..
4) Database
output value:
We can use Database output
values to output the value of the contents of database cells.
Navigation:
Insert menu> output value >
Database output value> choose specify SQL statements manually >click next
>click create >Select Machine Data source > Select Driver
(QT_flight32) > click ok > enter SQL statement (select *from orders) >
click finish > select data cells > click ok > Run and it will capture
and see the results in run time table.
5) XML
output value (from application):
we can use XML output values to
output the values of XML elements in XML documents.
Navigation:
Keep tool under recording mode with web environment > Insert menu > output
value > XML output value from application > Show the XML document > select
elements > click ok >stop recording.
6) XML output Value (From Resource):
We can use XML output values to
output the values of XML elements in
XML documents.
Navigation:
Insert
menu >output value> XML output value from resource > browse path of
the XML file > click ok > select elements >click ok.
Adding
Comments
Purpose of Comments:
- For making the script understandable
- For making the Script Disable from execution
Syntax:
- Use Apostrophe (‘) before the statement
- Use REM Command with single space before the statement
Comment a Block of Statements:
Navigation:
Select block of statements > Edit menu> Advanced> Comment block
Or
After
selecting block of statements use shortcut key Ctrl+M
Uncomment a block of statements:
Navigation: Select comment block>Edit menu>
Advanced>Uncomment block
Or
After
selecting comment block, Use shortcut key ctrl+shift+M
Inserting Flow Control Statements
QTP
adapted VB script engine for applying programming logic to tests. We can insert
VB script conditional statements and loop statements for applying the logic.
In VB
script there are 2 types of conditional statements and four types of loop
statements available.
Synchronization
It is a process of matching the
speeds of both QTP and AUT in order to get proper execution and results.
Where Synchronization is required:
During test execution QTP gives
instructions one by one with same speed, but AUT takes less time for some
operations execution and more time for some operations execution, that time we
may not get proper execution and results. In order to get proper results in
between QTP & AUT synchronization is required.
There are several methods available in QTP for synchronization.
1.
Inserting Wait statements.
2.
Inserting Synchronization points.
3.
Increasing Tool default synchronization time.
4.
Sync Method (Only for WEB)
5.
Exist Property
Inserting Wait Statements:
We can insert wait statements
in our test in order to make QTP to wait until AUT completes current operation.
Syntax:
Wait(time in seconds)
Note: If we insert wait
statements QTP waits up to maximum time even though operation is completed.
Inserting Synchronization point:
Place cursor in desired
location>keep tool under recording mode > Insert menu > Synchronization
point > show the object > click ok > select property name & Value
(True)>enter time in Mille seconds>click ok>Stop recording.
Note: if we insert
Synchronization points, it does not wait up to maximum time, after completion
of the current operations, it goes to next step immediately.
Syntax:
object hierarchy.waitproperty
“property name”,value,time in milli seconds.
Increasing Tool default
synchronization time:
Navigation:
File>settings>run tab>increase object synchronization
time out>apply>ok
Note: If we increase QTP tool
default time that can be applied for all statements in the test, but QTP does
not wait up to maximum time unnecessarily, After completion of one statement
execution it goes to next statement immediately.
Sync Method: (only for WEB)
Waits for the browser to complete current navigation.
Syntax: Object Hirearchy.Sync
Ex: Browser("Yahoo!
Toolbar").Page("Yahoo! Toolbar").Sync
Selecting an appropriate Method:
1.
Suppose in our test one or more statements only are taking more
time for execution then selecting “Inserting synchronization method” is better.
2.
Suppose in our test more statements are taking more time for
execution then selecting “increasing tool time out” .
3.
Above two are local features but wait statement is Vbscript
feature, even though some drawbacks are there in using wait statement, it is
better to use wait statement in functions.
Inserting Transaction
Points
We can insert Transaction points for measuring Transaction time.
It is a performance concept but QTP supports measuring transaction
time per user only.
Syntax:
Services.StartTransaction "name of the transaction"
-------
statements
---------
--------
services.EndTransaction "name of the transaction"
Note: We can insert multiple
transactions points in a test.
Parameterization
Passing parameters, through
this concept we can pass multiple values.
We use parameterization in Data
Driven Testing.
Data Driven Testing: Testing the Same operation
with multiple sets of test data.
Types of Parameterization:
We can parameterize tests in
several ways.
1.
Through Loop Statements
2.
Dynamic Test Data Submission
3.
Through Data Table
4.
Fetching Test Data directly from External files (Flat files &
Spreadsheets)
5.
Fetching Test Data directly from Databases (MS Acess, oracle etc).
6.
Getting Test Data from front end objects.
1. Through Loop Statements:
We can use loop statements for
passing sequential numbers & Logical Numbers.
Note: We can’t generate Strings.
For orderno=1 to 10 step 1 '
for one increment step keyword is not mandatory
Window("Flight
Reservation").Activate
Window("Flight
Reservation").WinButton("Button").Click
Window("Flight
Reservation").Dialog("Open Order").WinCheckBox("Order
No.").Set "ON"
Window("Flight
Reservation").Dialog("Open Order").WinEdit("Edit").Set
orderno
Window("Flight
Reservation").Dialog("Open
Order").WinButton("OK").Click
Next
2.Dynamic Test Data Submission:
Through Loop Statements we can
give strings also but every time user has to enter data.
For x=1 to 3
Agent =inputbox("enter an
Agent Name")
Password=inputbox("enter a
password")
invokeapplication
"C:\Program Files\Mercury Interactive\QuickTest
Professional\samples\flight\app\flight4a.exe"
Dialog("Login").Activate
Dialog("Login").WinEdit("Agent
Name:").Set Agent
Dialog("Login").WinEdit("Agent
Name:").Type micTab
Dialog("Login").WinEdit("Password:").SetSecure
password
Dialog("Login").WinButton("OK").Click
Window("Flight
Reservation").Close
Next
3. Through Data Table:
QTP adds one data table
(Spreadsheet) for every test, we can use Data Table for Data Driven Testing.
It has 3 types of usage
a. Entering
test data directly into data table and use
b. Importing
test data from external Flat files
c. Importing
test data from external Spread sheets
d. Importing
test data from Data bases.
A. Entering test data directly
into data table and use.
Steps: Generate the basic
test>open data table(View>Data Table)
Click on column header>enter
the name of the field (like this we can create number of columns) > Enter
Data>connect the data to test
(variable=datatable(“column
name”, Sheet id)
Example:
agent=datatable(“agent”,1)
Pass parameters.)
Run the test.
Agent =
Datatable("Agent",1)
pwd=Datatable
("Password",1)
invokeapplication
"C:\Program Files\Mercury Interactive\QuickTest
Professional\samples\flight\app\flight4a.exe"
Dialog("Login").Activate
Dialog("Login").WinEdit("Agent
Name:").Set Agent
Dialog("Login").WinEdit("Agent
Name:").Type micTab
Dialog("Login").WinEdit("Password:").SetSecure
pwd
Dialog("Login").WinButton("OK").Click
Window("Flight
Reservation").Close
b. Importing test data from external files:
Open Data Table (view>Data
table)>place mouse pointer on data table and right click>file>import
from file>Click ok>Browsw path of the file(it imports data from the flat
file)
Connecting Test Data to QTP
Test as above and run the test.
c. Importing test data from external Spread sheets:
Open Data Table (view>Data
table)>place mouse pointer on data table and right click>file>import
from file>Click ok>Browse path of the excel sheet (it imports data from
the excel sheet)
Connecting Test Data to QTP
Test as above and run the test.
D. Importing test data from
Data bases: Through Data table we can import Test Data from Data bases, but
first we have to create /get the DSN(Data source Name)& we have to use SQL
Commands.
1.
Creating
a Test Database: open MS Access (or we can use any other database).
Start programs>MS
Office>MS Access>file >new>Select blank Database>enter name of
the database>Save with mdb extension.
Creating Tables: Select Create
table in design view>Enter field name(Agent)and Select data type(text) Like
this we can create number of fields>save&enter table name.
Entering Data into Tables:
Select table>enter the data.
Creating DSN & importing data
Navigation: view>data
table>Place mouse pointer on Data table>sheet>import>from
database(Database query wizard opens)>choose ‘specify SQL statements
manually>click next >click create>click new>select driver type>click
next >browse path to store> enter DSN Name>Click Save>click
next>click finish>select>browse the database& select>click
ok>click ok>select DSN>click ok>enter SQL statement (select *from
login)>click finish.
Note: DSN Creation is one time
activity, by using the DSN we can get data for number of tests.
4.
Fetching
Test Data directly from Flat files
5). Fetching
Test Data directly from Excel Sheets
6) Fetching
Test Data directly from Databases
Environment
Variables in QTP
These
are global variables; if we want to use some variables globally (From number of
tests) declaring as global variables is better. If we declare as local
variables in number of tests, modifications are difficult.
Types of Environment variables:
1.
Built in variables: These are system
defined variables, we can access from all tests but these are designed as read
only.
2.
User defined variables: Variables that
we predefine in the active external environment variables file. We can create
as many files as we want and we can change values of variables.
Usage of environment variables:
Syntax:
Variable = Environment(“environment variable name”)
Ex:
X=Environment (“ActionName”)
Msgbox x
Example Script:
ProductDir =environment ("ProductDir")
app= "\samples\flight\app\flight4a.exe"
Systemutil.Run ProductDir & app
Dialog("Login").Activate
Dialog("Login").WinEdit("Agent Name:").Set
"gcreddy"
Dialog("Login").WinEdit("Password:").SetSecure
"4b3c86f2107ff565cc195ba6c24739091b656407"
Dialog("Login").WinButton("OK").Click
Creating user defined environment variables:
Navigation:
File > settings > Environment > select variable type as
user defined > click add icon (+) > enter variable name & Value >
click ok (like this we can create number of variables) > click export >
browse path & enter file name, save with xml extension > click ok.
Associating environment variable file:
Navigation:
File > settings >Environment > select variable type as
user defined > check “load variables and values from the external file” >
browse path of the xml file > click apply & ok.
Or
We can load environment file directly
Environment.loadfromfile”path of the xml file”
Usage of user defined Environment variables:
Associate environment file to current test:
Variable = Environment (“Variable Name”)
X=environment (“city”)
Msgbox x
Modifying Environment files:
Select XML file>open with notepad>modify the values>Save.
Actions

1.0 Introduction
- VBScript is a scripting language.
- A scripting language is a lightweight programming language.
- VBScript is a light version of Microsoft's programming language Visual Basic.
When a
VBScript is inserted into a HTML document, the Internet browser will read the
HTML and interpret the VBScript. The VBScript can be executed immediately, or
at a later event.
Microsoft Visual Basic Scripting Edition
brings active scripting to a wide variety of environments, including Web client
scripting in Microsoft Internet Explorer and Web server scripting in Microsoft
Internet Information Service.
1.1
Windows Script Host (WSH)
It is a Windows administration tool. WSH creates
an environment for hosting scripts. That is, when a script arrives at your
computer, WSH plays the part of the host — it makes objects and services
available for the script and provides a set of guidelines within which the
script is executed. Among other things, Windows Script Host manages security
and invokes the appropriate script engine
Windows Script Host is built into Microsoft
Windows 98, 2000, and Millennium Editions and higher versions.
The most commonly available text editor is already installed on our computer — Notepad. We can also use your favorite HTML editor, VbsEdit, Microsoft Visual C++, or Visual InterDev.
1.2 Creating a script with Notepad
- Start Notepad.
- Write
your script. For example purposes, type
Msgbox "Hello VB Script"
- Save
this text file with a .vbs extension (instead of the default .txt
extension). For example,
Hello.vbs
- Navigate to the file you just saved, and double-click it.
- Windows Script Host invokes the VB Script engine and runs your script. In the example, a message box is displayed with the message "Hello VB Script"
1.3 Hosting Environments and Script Engines
Scripts are often embedded in Web pages, either in an HTML page (on the client side) or in an ASP page (on the server side). In the case of a script embedded in an HTML page, the engine component that interprets and runs the script code is loaded by the Web browser, such as Internet Explorer. In the case of a script embedded in an ASP page, the engine that interprets and runs the script code is built into Internet Information Services (IIS).Windows Script Host executes scripts that exist outside an HTML or ASP page and that stand on their own as text files.
1.4 Available Script Engines
Generally, we write scripts in either Microsoft JScript or VBScript, the two script engines that ship with Microsoft Windows 98, 2000 and Millennium Editions. We can use other script engines, such as Perl, REXX, and Python, with Windows Script Host.A stand-alone script written in JScript has the .js extension; a stand-alone script written in VBScript has the .vbs extension. These extensions are registered with Windows. When we run one of these types of files, Windows starts Windows Script Host, which invokes the associated script engine to interpret and run the file.
2.0 Comments
The comment argument is the text of
any comment we want to include.2.0 Purpose of comments:
o
We
can use comments for making the script understandable.
o
We
can use comments for making one or more statements disable from execution.
2.1 Syntax
Rem comment (After the Rem keyword, a space is required before
comment.)
Or
Apostrophe
(') symbol before the comment
2.2 Comment/Uncomment a block of
statements
- Select block of statement and use short cut key Ctrl + M (for comment)
- Select comment block and use short cut key Ctrl + Shift + M (for uncomment)
3.0 VB Script Variables
A variable is a convenient placeholder that
refers to a computer memory location where we can store program information
that may change during the time our script is running.
3.1 Declaring Variables
We declare variables explicitly
in our script using the Dim statement, the Public statement, and the Private statement.For example:
Dim city
Dim x
We declare multiple variables by separating each variable name with a comma. For example:
Dim x, Top, Bottom, Left, Right
We can also declare a variable implicitly by
simply using its name in our script. That is not generally a good practice
because we could misspell the variable name in one or more places, causing
unexpected results when our script is run. For that reason, the Option Explicit statement is
available to require explicit declaration of all variables. The Option Explicit statement should be the first statement in our script.
3.2 Option Explicit
Forces explicit declaration of all variables in a script.
Option Explicit
' Force explicit variable declaration.
Dim MyVar ' Declare variable.
MyInt = 10 ' Undeclared variable generates error.
MyVar = 10 ' Declared variable does not generate error.
3.3 Naming Restrictions for Variables
- Must begin with an alphabetic character.
- Cannot contain an embedded period.
- Must not exceed 255 characters.
- Must be unique in the scope in which it is declared.
3.4 Scope of Variables
- A variable's scope is determined by where you declare it.
o
When
we declare a variable within a procedure, only code within that procedure can
access or change the value of that variable
o
If
we declare a variable outside a procedure, we make it recognizable to all the
procedures in our script. This is a script-level variable, and it has
script-level scope.
3.5 Life Time of Variables
o
The lifetime of a variable depends on how long it exists.
o
The lifetime of a script-level variable extends from the time it
is declared until the time the script is finished running.
o At
procedure level, a variable exists only as long as you are in the procedure.
3.6
Assigning Values to Variables
Values are assigned to variables creating an
expression as follows: The variable is on the left side of the expression and the value you want to assign to the variable is on the right.
For example:
B = 200
City = “Hyderabad”
3.7
Scalar Variables and Array Variables
A variable
containing a single value is a scalar variable.
A variable
containing a series of values, is called an array variable.
Array variables and scalar variables are declared
in the same way, except that the declaration of an array variable uses parentheses
() following the variable name.
Example:
Dim A(3)
Although the number shown in the parentheses is 3, all arrays in VBScript are zero-based, so this array actually contains 4 elements.
A(0) = 256
A(1) = 324
A(2) = 100
A(3) = 55
For example:
SomeVariable = A(4)
Arrays aren't limited to a single dimension. You can have as many as 60 dimensions, although most people can't comprehend more than three or four dimensions.
Arrays aren't limited to a single dimension. We can have as many as 60 dimensions, although most people can't comprehend more than three or four dimensions.
In the following example, the MyTable
variable is a two-dimensional array consisting of 6 rows and 11 columns:
Dim MyTable(5, 10)
In a two-dimensional array, the first number
is always the number of rows; the second number is the number of columns.
3.8 Dynamic Arrays
We can also declare an array whose size changes during the time our script is running. This is called a dynamic array.
The array is initially declared within a
procedure using either the Dim statement or using the ReDim statement. However, for a dynamic array, no size or number of dimensions is placed inside the parentheses.
For example:
Dim MyArray()
ReDim AnotherArray()
To use a dynamic array, you must subsequently use ReDim to determine the number of dimensions and the size of each dimension.
In the following example, ReDim sets
the initial size of the dynamic array to 25. A subsequent ReDim
statement resizes the array to 30, but uses the Preserve keyword to
preserve the contents of the array as the resizing takes place. ReDim MyArray(25)
ReDim Preserve MyArray(30)
There is no limit to the number of times we
can resize a dynamic array, although if we make an array smaller, we lose the
data in the eliminated elements.
4.0 VB Script Data Types
VBScript has only one data type called a Variant. A Variant
is a special kind of data type that can contain different kinds of information,
depending on how it is used. Because Variant is the only data type in
VBScript, it is also the data type returned by all functions in VBScript.
4.1 Variant Subtypes
Beyond the simple numeric or string classifications, a Variant can make further distinctions about the specific nature of numeric information. For example, we can have numeric information that represents a date or a time. When used with other date or time data, the result is always expressed as a date or a time. We can also have a rich variety of numeric information ranging in size from Boolean values to huge floating-point numbers. These different categories of information that can be contained in a Variant are called subtypes. Most of the time, we can just put the kind of data we want in a Variant, and the Variant behaves in a way that is most appropriate for the data it contains.The following table shows subtypes of data that a Variant can contain.
Subtype
|
Description
|
Empty |
Variant is uninitialized. Value is 0 for numeric variables
or a zero-length string ("") for string variables. |
Null |
Variant
intentionally contains no valid data.
|
Boolean
|
|
Byte
|
Contains integer in the range 0 to 255.
|
Integer
|
Contains integer in the range -32,768 to
32,767.
|
Currency
|
-922,337,203,685,477.5808 to
922,337,203,685,477.5807.
|
Long
|
Contains integer in the range -2,147,483,648 to
2,147,483,647.
|
Single
|
Contains a single-precision, floating-point number
in the range -3.402823E38 to -1.401298E-45 for negative values; 1.401298E-45
to 3.402823E38 for positive values.
|
Double
|
Contains a double-precision, floating-point
number in the range -1.79769313486232E308 to -4.94065645841247E-324 for
negative values; 4.94065645841247E-324 to 1.79769313486232E308 for positive
values.
|
Date (Time)
|
Contains a number that represents a date
between January 1, 100 to December 31, 9999.
|
String
|
Contains a variable-length string that can be
up to approximately 2 billion characters in length.
|
Object
|
Contains an object.
|
Error
|
Contains an error number.
|
We can use conversion functions to convert data from one subtype to another. In addition, the VarType function returns information about how your data is stored within a Variant.
5.0 VB Script Operators
Operators are used for performing mathematical, comparison
and logical operations.
VBScript has a full range of operators, including arithmetic
operators, comparison
operators, concatenation
operators, and logical operators.
4.1 Operator Precedence
When several operations
occur in an expression, each part is evaluated and resolved in a predetermined
order called operator precedence. We can use parentheses to override the order of precedence and force some parts of an expression to be evaluated before others.
Operations within parentheses are always performed before those outside. Within parentheses, however, standard operator precedence is maintained.
When expressions contain operators from more than one category, arithmetic operators are evaluated first, comparison operators are evaluated next, and logical operators are evaluated last.
Comparison operators all have equal precedence; that is, they are evaluated in the left-to-right order in which they appear.
Arithmetic and logical operators are evaluated in the following order of precedence.
4.2 Arithmetic Operators:
4.3 Comparison Operators
Used to compare expressions.

6.1 InputBox Function
Displays a prompt in a dialog box, waits for
the user to input text or click a button, and returns the contents of the text
box.Example:
Dim Input
Input = InputBox("Enter your name")
MsgBox ("You entered: " & Input)
6.2 MsgBox Function
Displays a message in a dialog box, waits for
the user to click a button, and returns a value indicating which button the
user clicked.Example:
Dim MyVar
MyVar = MsgBox ("Hello World!", 65, "MsgBox Example")
' MyVar contains either 1 or 2, depending on which button is clicked.
7) VB Script Constants
A constant is a meaningful name that takes the place of a number or string and never changes.
7.1 Creating Constants
We create user-defined constants in VBScript
using the Const statement. Using the Const
statement, we can create string or numeric constants with meaningful names and
assign them literal values. Const statement
Declares constants for use in place of literal values.
Example:
Const MyString = "This is my string."
Const MyAge = 49
Const CutoffDate = #6-1-97#
Note that String literal is enclosed in quotation marks (" ").Represent Date literals and time literals by enclosing them in number signs (#).
We declare multiple constants by separating each constant name and value with a comma. For example:
Const price= 100, city= “Hyderabad”, x= 27
8) Conditional Statements
We can control the flow of our script with
conditional statements and looping statements. Using conditional statements, we can write VBScript code that makes decisions and repeats actions. The following conditional statements are available in VBScript:
1) If…Then…Else Statement
2) Select Case Statement
8.1 Making Decisions Using If...Then...Else
The If...Then...Else statement is used to evaluate whether a condition is True or False and, depending on the result, to specify one or more statements to run. Usually the condition is an expression that uses a comparison operator to compare one value or variable with another.
If...Then...Else statements can be nested to as many levels as you need.
8.1.1 Running a Statements if a Condition is True (single statement)
To run only one statement when a condition is True,
use the single-line syntax for the If...Then...Else statement.
Dim myDate
myDate = #2/13/98#
If myDate < Now Then myDate = Now
8.1.2 Running Statements if a Condition is True (multiple statements)
To run more than one line of code, we must
use the multiple-line (or block) syntax. This syntax includes the End If
statement. Dim x
x= 20
If x>10 Then
msgbox "Hello G.C.Reddy"
msgbox "x value is: "&x
msgbox "Bye Bye"
End If
8.1.3 Running Certain Statements if a Condition is True and Running Others if a Condition is False
We can use an If...Then...Else
statement to define two blocks of executable statements: one block to run if
the condition is True, the other block to run if the condition is False.
Example:
Dim x
x= Inputbox (" Enter a value")
If x>100 Then
Msgbox "Hello G.C.Reddy"
Msgbox "X is a Big Number"
Msgbox "X value is: "&X
Else
Msgbox "GCR"
Msgbox "X is a Small Number"
Msgbox "X value is: "&X
End If
8.1.4 Deciding Between Several Alternatives
A variation on the If...Then...Else
statement allows us to choose from several alternatives. Adding ElseIf
clauses expands the functionality of the If...Then...Else statement so
we can control program flow based on different possibilities. Example:
Dim x
x= Inputbox (" Enter a value")
If x>0 and x<=100 Then
Msgbox "Hello G.C.Reddy"
Msgbox "X is a Small Number"
Msgbox "X value is "&x
Else IF x>100 and x<=500 Then
Msgbox "Hello GCR"
Msgbox "X is a Medium Number"
Else IF x>500 and x<=1000 Then
Msgbox "Hello Chandra Mohan Reddy"
Msgbox "X is a Large Number"
Else
Msgbox "Hello Sir"
Msgbox "X is a Grand Number"
End If
End If
End If
8.1.5 Executing a certain block of
statements when two / more conditions are True (Nested If...)
Example:
Dim State, Region
State=Inputbox ("Enter a State")
Region=Inputbox ("Enter a Region")
If state= "AP" Then
If Region= "Telangana" Then
msgbox "Hello G.C.Reddy"
msgbox "Dist count is 10"
Else if Region= "Rayalasema" Then
msgbox "Hello GCR"
msgbox "Dist count is 4"
Else If Region= "Costal" Then
msgbox "Hello Chandra mohan Reddy"
msgbox "Dist count is 9"
End If
End If
End If
End If
8.2 Making Decisions with Select Case
The Select Case structure provides an
alternative to If...Then...ElseIf for selectively executing one block of
statements from among multiple blocks of statements. A Select Case
statement provides capability similar to the If...Then...Else statement,
but it makes code more efficient and readable.
Example:
Option explicit
Dim x,y, Operation, Result
x= Inputbox (" Enter x
value")
y= Inputbox ("Enter y
value")
Operation= Inputbox ("Enter an
Operation")
Select Case Operation
Case
"add"
Result=
cdbl (x)+cdbl (y)
Msgbox
"Hello G.C.Reddy"
Msgbox
"Addition of x,y values is "&Result
Case
"sub"
Result=
x-y
Msgbox
"Hello G.C.Reddy"
Msgbox
"Substraction of x,y values is "&Result
Case
"mul"
Result= x*y
Msgbox
"Hello G.C.Reddy"
Msgbox
"Multiplication of x,y values is "&Result
Case
"div"
Result=
x/y
Msgbox
"Hello G.C.Reddy"
Msgbox
"Division of x,y values is "&Result
Case
"mod"
Result=
x mod y
Msgbox
"Hello G.C.Reddy"
Msgbox
"Mod of x,y values is "&Result
Case
"expo"
Result=
x^y
Msgbox
"Hello G.C.Reddy"
Msgbox"Exponentation
of x,y values is "&Result
Case
Else
Msgbox
"Hello G.C.Reddy"
msgbox
"Wrong Operation"
End Select

9) Looping Through Code
o
Looping allows us
to run a group of statements repeatedly.
o
Some loops repeat
statements until a condition is False;
o
Others repeat
statements until a condition is True.
o
There are also
loops that repeat statements a specific number of times.
The following looping
statements are available in VBScript:- Do...Loop: Loops while or until a condition is True.
- While...Wend: Loops while a condition is True.
- For...Next: Uses a counter to run statements a specified number of times.
- For Each...Next: Repeats a group of statements for each item in a collection or each element of an array.
9.1 Using Do Loops
We can use Do...Loop statements to run a block of statements an indefinite number of times. The statements are repeated either while a condition is True or until a condition becomes True.
9.1.1 Repeating Statements While a Condition is True
Repeats a block of statements while a condition is True or until a condition becomes Truea) Do While condition
Statements
-----------
-----------
LoopOr, we can use this below syntax:
Example:
Dim x
Do While x<5 x=x+1
Msgbox "Hello G.C.Reddy"
Msgbox "Hello QTP"
Loop
b) Do
Statements
-----------
-----------
Loop While condition
Example:
Dim x
x=1
Do
Msgbox "Hello G.C.Reddy"
Msgbox "Hello QTP"
x=x+1
Loop While x<5
9.1.2 Repeating a Statement Until a Condition Becomes True
c) Do Until condition
Statements
-----------
-----------
LoopOr, we can use this below syntax:
Example:
Dim x
Do Until x=5 x=x+1
Msgbox "G.C.Reddy"
Msgbox "Hello QTP"
Loop
Or, we can use this below syntax:d) Do
Statements
-----------
-----------
Loop Until conditionOr, we can use this below syntax:
Example:
Dim x
x=1
Do
Msgbox “Hello G.C.Reddy”
Msgbox "Hello QTP"
x=x+1
Loop Until x=5
9.2 While...Wend Statement
Executes a series of statements as long as a given condition is True.Syntax:
While condition
Statements
-----------
-----------
Wend
Example:
Dim x
x=0
While
x<5 x=x+1
msgbox
"Hello G.C.Reddy"
msgbox
"Hello QTP"
Wend
9.3 For...Next Statement
Repeats a group of statements a specified number of times.
Syntax:
For counter = start
to end [Step step]
statements
Next
Example:
Dim x
For x= 1 to 5 step 1
Msgbox "Hello G.C.Reddy"
Next
9.4 For Each...Next Statement
Repeats a group of statements for each element in an array or collection.
Syntax:
For Each item In array
Statements
Next
Example:
Dim a,b,x (3)
a=20
b=30
x(0)= "Addition is "&
a+b
x(1)="Substraction is "
& a-b
x(2)= "Multiplication is " & a*b
x(3)= "Division is "
& a/b
For Each element In x
msgbox element
Next
Example:
MyArray =
Array("one","two","three","four","five")
For Each element In MyArray
msgbox element
Next
For Each element In MyArray
msgbox element
Next
10) VB Script Procedures
In VBScript, there are two kinds of procedures; the Sub procedure and the Function procedure.11.1 Sub Procedures
A Sub procedure is a series of VBScript statements (enclosed by Sub and End Sub statements) that perform actions but don't return a value.A Sub procedure can take arguments (constants, variables, or expressions that are passed by a calling procedure).
If a Sub procedure has no arguments, its Sub statement must include an empty set of parentheses ().
Syntax:
Sub Procedure name ()
Statements
-----------
-----------
End Sub
Or
Sub Procedure name (argument1, argument2)
Statements
-----------
-----------
End Sub
Example: 1
Sub ConvertTemp()
temp = InputBox("Please enter the temperature in degrees F.", 1)
MsgBox "The temperature is " & Celsius(temp) & " degrees C."
End Sub
Example: 2
11.2 Function Procedures
A Function procedure is a series of VBScript statements enclosed by the Function and End Function statements.
A Function procedure is similar to a Sub procedure, but can also return a value.
A Function procedure can take arguments (constants, variables, or expressions that are passed to it by a calling procedure).
If a Function procedure has no arguments, its Function statement must include an empty set of parentheses.
A Function returns a value by assigning a value to its name in one or more statements of the procedure. The return type of a Function is always a Variant.
Syntax:
Function Procedure name ()
Statements
-----------
-----------
End Function
Or
Function Procedure name (argument1, argument2)
Statements
-----------
-----------
End Function
Example: 1
Function Celsius(fDegrees)
Celsius = (fDegrees - 32) * 5 / 9
End Function
Example: 2
Function cal(a,b,c)
cal = (a+b+c)
End Function
11.3 Getting Data into and out of Procedures
o
Each piece of
data is passed into our procedures using an argument.
o
Arguments serve
as placeholders for the data we want to pass into our procedure. We can name
our arguments any valid variable name.
o
When we create a
procedure using either the Sub statement or the Function
statement, parentheses must be included after the name of the procedure.
o
Any arguments are
placed inside these parentheses, separated by commas.
11.4 Using Sub and Function Procedures in Code
A Function in our code must always be used on the right side of a variable assignment or in an expression.For example:
Temp = Celsius(fDegrees)
-Or-MsgBox "The Celsius temperature is " & Celsius(fDegrees) & " degrees."
To call a Sub procedure from another
procedure, type the name of the procedure along with values for any required
arguments, each separated by a comma. The Call statement is not required, but if you do use it, you must enclose any arguments in parentheses.
The following example shows two calls to the
MyProc
procedure. One uses the Call statement in the code; the other doesn't.
Both do exactly the same thing.
Call MyProc(firstarg, secondarg)
MyProc firstarg, secondarg
Notice that the parentheses are omitted in
the call when the Call statement isn't used.11) VB Script Built in Functions
1) Asc Function

msgbox x' It subtracts date1 from date2
x=DateDiff("m", date1,date2)' m for month
msgbox x' It subtracts date1 from date2
x=DateDiff("y", date1,date2) 'it considers days only
msgbox x' It subtracts date1 from date2
Note: through this function, we can day or month wise diffrence only.

msgbox a(5) 'Output: Error
By default, VBScript is not case sensitive and
does not differentiate between upper-case and lower-case spelling of words, for
example, in variables, object and method names, or constants.
For
example, the two statements below are identical in VBScript:
Browser("Mercury").Page("Find
a Flight:").WebList("toDay").Select "31"
21.2 Text strings:
When we enter a value as a text string, we must
add quotation marks before and after the string. For example, in the above
segment of script, the names of the Web site, Web page, and edit box are all
text strings surrounded by quotation marks.
Note
that the value 31 is also surrounded by quotation marks, because it is a text
string that represents a number and not a numeric value.
In
the following example, only the property name (first argument) is a text string
and is in quotation marks. The second argument (the value of the property) is a
variable and therefore does not have quotation marks. The third argument
(specifying the timeout) is a numeric value, which also does not need quotation
marks.
Browser("Mercury").Page("Find
a Flight:").WaitProperty("items count", Total_Items, 2000)
21.3 Variables:
We can specify variables to store strings,
integers, arrays and objects. Using variables helps to make our script more
readable and flexible
21.4 Parentheses:
To achieve the desired result and to avoid errors,
it is important that we use parentheses () correctly in our statements.
21.5 Indentation:
21.6 Comments:
We can add comments to our
statements using an apostrophe ('), either at the beginning of a separate line,
or at the end of a statement. It is recommended that we add comments wherever
possible, to make our scripts easier to understand and maintain.
21.7 Spaces:
We can add extra blank
spaces to our script to improve clarity. These spaces are ignored by VBScript.
13) Errors
We have two types Errors in VB Script; they are VBScript Run-time Errors and VBScript Syntax Errors13.1 VBScript Run-time Errors
VBScript run-time errors are errors
that result when our VBScript script attempts to perform an action that the
system cannot execute. VBScript run-time errors occur while our script is being
executed; when variable expressions are being evaluated, and memory is being
dynamic allocated.
13.2 VBScript Syntax Errors
VBScript syntax errors are errors that result when the
structure of one of our VBScript statements violates one or more of the
grammatical rules of the VBScript scripting language. VBScript syntax errors
occur during the program compilation stage, before the program has begun to be
executed.
File
System Operations
File System Object Model:
The File System Object (FSO) model
provides an object-based tool for working with folders and files. It allows us
to use the familiar object. method syntax with a rich set of properties,
methods, and events to process folders and files. We can also employ the
traditional Visual Basic statements and commands.
The FSO model gives our application the
ability to create, alter, move, and delete folders, or to determine if and
where particular folders exist. It also enables us to get information about
folders, such as their names and the date they were created or last modified.
The FSO model makes processing files
much easier as well. When processing files, our primary goal is to store data
in an efficient, easy-to-access format. We need to be able to create files,
insert and change the data, and output (read) the data. Although we can store
data in a database, doing so adds a significant amount of overhead to our
application. We may not want to have such overhead, or our data access
requirements may not call for the extra functionality associated with a
full-featured database. In this case, storing our data in a text file or binary
file is the most efficient solution.
The FSO model, contained in the
Scripting type library (Scrrun.dll), supports the creation and manipulation of
text files through the TextStream object; however, the FSO model does not
support binary files. To manipulate binary files, use the FileOpen Function
with the Binary keyword.

Database Operations
ADO (Active Data Objects), this technology
allows users to access data easily from many existing databases (such as Access
or Paradox) or from ODBC compliant databases like Oracle or MS SQL Server.
Using ADO is
quite simple and allows programmers to provide flexible database front ends to
users that are reliable and include many features.
Following
are some of the key objects found in the ADO
object model and some of their key methods and properties.
Connection
Object
This
object represents an open connection to the data source. This connection can be
a local connection (say App.Path) or can be across a network in a client server
application. Some of the methods and properties of this object are not available
depending on the type of data source connected to.
Command Object
A command object specifies a specific
method we intend to execute on or against the data source accessed by an open
connection.
RecordSet Object
The RecordSet object represents a complete
set of records from an executed command or from an underlying base table in the
database. A key thing to note is that a RecordSet object references only one
record at a time as the current record.

Object Identification Configuration
Overview:
Generally for every object 20-25 properties information available, qtp recognizes object using 2 0r 3 important properties.
Qtp has default object identification configuration for every environment, if we feel that configuration is not sufficient for recognizing objects in our application, we can configure some more
Object Identification Types
a) Normal identification
1) Mandatory properties
2) Assistive properties
b) Smart identification
1) base filter properties
2) optional filter properties
c) Ordinal identifier

Object Identification Types
a) Normal identification
1) Mandatory properties
2) Assistive properties
b) Smart identification
1) base filter properties
2) optional filter properties
c) Ordinal identifier
1)
location
2) index
3) creation time(only for web)
QTP learns information in the following in case of normal identification:
First of all the qtp learns all the mandatory properties at a time and thinks whether these properties sufficient to identify the object uniquely. if it feels sufficient then it stops learning otherwise,
It learns first assistive property and once again stops and thinks, like this qtp learns one by one. At the end of assistive properties list also if it feels not satisfied and it finally goes to Ordinal Identifier.
QTP learns information in the following in case of Smart Identification:
Smart identification is an optional feature, if we feel normal identification is not sufficient for any object, and then we configure Smart Identification for that object, in order to avoid Ordinal Identifier.
After normal identification if qtp feels not satisfied then it goes to smart identification. in smart identification 2 types of properties available, first qtp learns all base filter properties at a time and thinks whether these properties are sufficient for identifying the object uniquely. If it feels sufficient, then it stops learning otherwise it goes Optional Filter Properties and learns one by one. Still it feels not satisfied finally it goes to Ordinal Identifier.
Ordinal identifiers:
There are 3 types of ordinal identifiers available
2) index
3) creation time(only for web)
QTP learns information in the following in case of normal identification:
First of all the qtp learns all the mandatory properties at a time and thinks whether these properties sufficient to identify the object uniquely. if it feels sufficient then it stops learning otherwise,
It learns first assistive property and once again stops and thinks, like this qtp learns one by one. At the end of assistive properties list also if it feels not satisfied and it finally goes to Ordinal Identifier.
QTP learns information in the following in case of Smart Identification:
Smart identification is an optional feature, if we feel normal identification is not sufficient for any object, and then we configure Smart Identification for that object, in order to avoid Ordinal Identifier.
After normal identification if qtp feels not satisfied then it goes to smart identification. in smart identification 2 types of properties available, first qtp learns all base filter properties at a time and thinks whether these properties are sufficient for identifying the object uniquely. If it feels sufficient, then it stops learning otherwise it goes Optional Filter Properties and learns one by one. Still it feels not satisfied finally it goes to Ordinal Identifier.
Ordinal identifiers:
There are 3 types of ordinal identifiers available
1) Location: is based on object location in the AUT ,location starts from zero.
2) index: it is
based on sequence of the programs, index starts from zero
3) Creation time: it
is based on loading time of the web objects. qtp generates 0,1,2 like numbers.
Tool Settings Globalization:
As QTP is a I-tier(Stand-alone) application,making Tool settings globally is not possible.
For making tool settings global, QTP is providing a special feature called "Generate Script".
STEPS:
1) Settings available in 3 areas.
a) File->Settings
b) Tools->Options
c) Tools->Object Identification
2) Perform required settings and generate Scripts
3) Share Script files to team members and ask them to execute those scripts.
NOTE: After executing these scripts all team members can get same settings.

Regular Expressions in QTP
What is Regular Expression?
It is a way
of representing data using symbols. They are often used within matching,
searching or replacing algorithms.
Regular Expressions in QTP:
Regular
expressions can be used in QTP for identifying objects and text strings with
varying values.
Where we use:
o Defining
the property values of an object in Descriptive programming for handling
dynamic objects
o For
parameterizing a step
o creating
checkpoints with varying values
Using
Regular Expressions in QTP:
We can define a regular expression for a constant value, a Data Table parameter value, an Environment parameter value, or a property value in Descriptive programming.
We can define a regular expression in standard checkpoint to verify the property values of an object; we can set the expected value of an object's property as a regular expression so that an object with a varying value can be verified.
We can define the text string as a regular expression, when creating a text checkpoint to check that a varying text string is displayed on our application,
For XML checkpoints we can set attribute or element values as regular expressions.
Ways of Regular Expressions:
a) Backslash Character:
A backslash (\) can serve two purposes. It can be used in conjunction with a special character to indicate that the next character be treated as a literal character.
Alternatively, if the backslash (\) is used in conjunction with some characters that would otherwise be treated as literal characters, such as the letters n, t, w, or d, the combination indicates a special character.
b) Matching Any Single Character:
A period (.) instructs QTP to search for any single character (except for \n).
Ex:
welcome.
Matches welcomes, welcomed, or welcome followed by a space or any other single character.
c)
Matching Any Single Character in a List:
Square brackets
instruct QTP to search for any single character within a list of characters.
Ex:
To search for the date 1867, 1868, or 1869, enter:
186[789]
Ex:
To search for the date 1867, 1868, or 1869, enter:
186[789]
d)
Matching Any Single Character Not in a List:
When a caret (^) is the first character inside square brackets, it instructs QTP to match any character in the list except for the ones specified in the string.
Example:
[^ab]
Matches any character except a or b.
e)
Matching Any Single Character within a Range:
To match a single character within a range, we can use square brackets ([ ]) with the hyphen (-) character.
Example:
For matching any year in the 2010s, enter:
201[0-9]
f)
Matching Zero or More Specific Characters:
An asterisk (*) instructs QTP to match zero or more occurrences of the preceding character.
For example:
ca*r
Matches car, caaaaaar, and cr
g)
Matching One or More Specific Characters:
A plus sign (+) instructs QTP to match one or more occurrences of the preceding character.
For example:
ca+r
Matches car and caaaaaar, but not cr.
h) Matching
Zero or One Specific Character:
A question mark (?) instructs QTP to match zero or one occurrences of the preceding character.
For example:
ca?r
Matches car and cr, but nothing else.
i)
Grouping Regular Expressions:
Parentheses (()) instruct QTP to treat the contained sequence as a unit, just as in mathematics and programming languages. Using groups is especially useful for delimiting the argument(s) to an alternation operator ( | ) or a repetition operator ( * , + , ? , { } ).
j)
Matching One of Several Regular Expressions:
A vertical line (|) instructs QTP to match one of a choice of expressions.
k)
Matching the Beginning of a Line:
A caret (^) instructs QTP to match the expression only at the start of a line, or after a newline character.
l) Matching the End of a Line:
A dollar sign ($) instructs QTP to match the expression only at the end of a line, or before a newline character.
m)
Matching Any AlphaNumeric Character Including the Underscore:
\w instructs QTP to match any alphanumeric character and the underscore (A-Z, a-z, 0-9, _).
n)
Matching Any Non-AlphaNumeric Character:
\W instructs QTP to match any character other than alphanumeric characters and underscores.
o)
Combining Regular Expression Operators:
We can combine regular expression operators in a single expression to achieve the exact search criteria we need.
For example,
start.*
Matches start, started, starting, starter, and so forth.
we can use a combination of brackets and an asterisk to limit the search to a combination of non-numeric characters.
For example:
[a-zA-Z]*
To match any number between 0 and 1200, we need to match numbers with 1 digit, 2 digits, 3 digits, or 4 digits between 1000-1200.
The regular expression below matches any number between 0 and 1200.
([0-9]?[0-9]?[0-9]|1[01][0-9][0-9]|1200)
RegExp object
VB Script is
providing RegExp object for defining Regular expressions, It provides simple
support for defining regular expressions.
Regular Expression
Object Properties and Methods:
Properties:
a) Global Property
b) IgnoreCase
Property
c) Pattern Property
Methods:
a) Execute Method
b) Replace Method
c) Test Method
Regular Expressions Examples:
1) Match
File Names in a Directory against Regular Expression
Set objFS = CreateObject("Scripting.FileSystemObject")
Set objShell = CreateObject("WScript.Shell")
strCurrentDirectory = objShell.CurrentDirectory
Set objFolder = objFS.GetFolder(strCurrentDirectory)
Set colFiles = objFolder.Files
Set objRE = New RegExp
objRE.Global = True
objRE.IgnoreCase = False
objRE.Pattern = WScript.Arguments(0)
For Each objFile In colFiles
bMatch = objRE.Test(objFile.Name)
If bMatch Then
WScript.Echo objFile.Name
End If
Next
2) Match Content in a File against a Regular Expression
strFileName = "E:\gcreddy.txt"
Set objFS = CreateObject("Scripting.FileSystemObject")
Set objTS = objFS.OpenTextFile(strFileName)
strFileContents = objTS.ReadAll
WScript.Echo "Searching Within: "
WScript.Echo strFileContents
objTS.Close
Set objRE = New RegExp
objRE.Global = True
objRE.IgnoreCase = False
objRE.Pattern = WScript.Arguments(0)
Set colMatches = objRE.Execute(strFileContents)
WScript.Echo vbNewLine & "Resulting Matches:"
For Each objMatch In colMatches
WScript.Echo "At position " & objMatch.FirstIndex & " matched " & objMatch.Value
Set objFS = CreateObject("Scripting.FileSystemObject")
Set objShell = CreateObject("WScript.Shell")
strCurrentDirectory = objShell.CurrentDirectory
Set objFolder = objFS.GetFolder(strCurrentDirectory)
Set colFiles = objFolder.Files
Set objRE = New RegExp
objRE.Global = True
objRE.IgnoreCase = False
objRE.Pattern = WScript.Arguments(0)
For Each objFile In colFiles
bMatch = objRE.Test(objFile.Name)
If bMatch Then
WScript.Echo objFile.Name
End If
Next
2) Match Content in a File against a Regular Expression
strFileName = "E:\gcreddy.txt"
Set objFS = CreateObject("Scripting.FileSystemObject")
Set objTS = objFS.OpenTextFile(strFileName)
strFileContents = objTS.ReadAll
WScript.Echo "Searching Within: "
WScript.Echo strFileContents
objTS.Close
Set objRE = New RegExp
objRE.Global = True
objRE.IgnoreCase = False
objRE.Pattern = WScript.Arguments(0)
Set colMatches = objRE.Execute(strFileContents)
WScript.Echo vbNewLine & "Resulting Matches:"
For Each objMatch In colMatches
WScript.Echo "At position " & objMatch.FirstIndex & " matched " & objMatch.Value

Automation
Framework
Automation:
Accessing one Software Objects from another Software is called
Automation.
(AUT is one s/w and Testing Tool is another s/w.)
Automation Framework:
It is a set of guidelines, assumptions and process developed by
experts in order to perform a task(s) in an effective, efficient and optimized
way.
Or
A systematic approach to automate software Test process
Why Automation Framework:
In one project test automation we use various files, we perform
various tasks, in order to organize and manage them all, a systematic approach
(Automation Framework) required.
Files to be used:
a) Flat files (.txt),
b) Excel files (.xls)
c) Object repository files (.tsr)
d) XML files (.xml)
e) Library files (.vbs/.qfl)
f) Test Scripts (.mts)
g) Test Batch Files (.mtb)
g) Test Batch Files (.mtb)
h) Recovery scenario files (.qrs)
i) Test Result file (.XML) Etc...
i) Test Result file (.XML) Etc...
Tasks to be performed:
a) Analyzing the application
b) Selecting Areas/Test Cases for Automation
c) Planning (Effort estimation, Schedule, Work allocation and
Automation Framework implementation)
d) Creating Generic and project specific functions.
e) Creating required Automation resources (Functions, Object
repository Files, Environment variable files---etc)
f) Creating Tests (Using Object Repository or Descriptive
Programming)
g) Enhancing Tests(Inserting Checkpoints, Output Values,
Transaction points, Flow Control Statements, Synchronization,
Parameterization---etc )
h) Debugging and running tests(Individual test execution, Test
Batch execution --etc)
i) Defining and exporting test results
j) Analyzing results
k) Test reporting
l) Defect Reporting using companies defect management system.
m) Modifying tests
n) Performing re and regression testing ---etc
Types Of Automation Framework:
Automation Framework is not a qtp feature, it’s a 3rd party
concept. And this is purely local concept.(framework may vary from one company
to another)
1.
Record/Playback or Linear Framework (1st
generation framework).
In this Framework we create tests using recording,low resources maintenance, Form batches and executing tests.
Drawbacks: Modifications and maintenance are difficult,less command on scripts,low performance ---etc
2.
Modular Framework.
In this Framework,reusable components can be recognized,first we
concentrate on creating reusable components, then creating tests using those
components.
Advantages:
It reduces test Automation time
Performance is high than recording and playback
Drawbacks:
Less usage of keywords, no concentration on Data driven testing
and low performance than latest Frameworks like Keyword Driven Framework.
3.
Data Driven Framework
In this Framework,we concentrate more on Data Driven testing.We
recognize positive and negative scenarios,then collecting test data and
parameterizing.
Advantages:
We can check reliability of the system,positive and negative
testing.
Drawbacks:
Less concentration on complex Functionality Testing and low
keywords usage.
4. Keyword Driven framework
5.
Hybrid Framework
In the above frameworks Keyword Driven framework is very famous in
the industry.
It is a mixing of more than one approach.
In this approach,we mix Data driven and Modular approaches OR Data Driven and Keyword Driven approaches---etc
Advantages:
Scope is very high as we mix different approaches,Flexible for performing any tasks.
Drawbacks:
Organizing and managing resources are difficult,complex architecture,low in performance.
NOTE: Now a days Mix of Data driven and Keyword driven approaches is a famous Hybrid Framework in the industry.
In this approach,we mix Data driven and Modular approaches OR Data Driven and Keyword Driven approaches---etc
Advantages:
Scope is very high as we mix different approaches,Flexible for performing any tasks.
Drawbacks:
Organizing and managing resources are difficult,complex architecture,low in performance.
NOTE: Now a days Mix of Data driven and Keyword driven approaches is a famous Hybrid Framework in the industry.
Keyword Driven Framework
Keyword:
1. Any word used as the key to a code
2 A reserved word used to identify a specific command, function
etc.
(in our test automation example keywords are :
Keywords to be used in Test Automation:
a) Test Objects (EX: Browser,page,webEdit,WinButton---etc)
b) Functions (Built-In and User defined)
c) Methods (Ex:Set,Select,Activate,Navigate---etc)
d) Statements (EX:Dim,If,For---etc)
e) Operators (EX: +,/,*,and,or,not---etc)
Keyword Driven Approach:
In
this approach we use keywords for preparing tests. First we create tests and
make them as functions, through framework we execute them and generate results.
Key elements of Automation Framework:
1. Well defined folder structure
2. Initialization script
3. Driver script
4. input data spreadsheet
5. process guidelines document
Why folder structure?
In order to create, store, organize and manage files a well
defined folder structure required. Folder structure is a mandatory element of
any framework, but folder names may vary from one framework to another and
company to another .
Folder Structure:
1. Object Repository
2. Environment
3. Library
a) Company
b) Project Specific
4. Test data
5. Test log
6. Recovery scenarios
7. Miscellaneous
And
1. Initialization script (.vbs file)
2. Driver script (QTP Script file)
1)
Object Repository: In this folder we
store object repository files(.tsr), all team members can use this
repositories.
2)
Environment: In
this folder we store environment variables files(.xml), all team members can
use this variables.
3)
Function Library:this folder contains two
sub folders one is for storing common functions of our company, another folder
for storing our project specific functions(.vbs).
4)
Test Data: in this folder we store test
data required for data driven testing, for that we use either .xls files or
.txt files or .mdb files.
5)
Test Log: In this folder we store test
result(excel sheet).
6)
Recovery scenarios: In this folder we
store qtp recovery scenarios files(.qrs).
7)
Miscellaneous: in this folder we store
the files other than above files(ex-process guideline doc and messages among
team members and instructions by team lead etc).
And
1)
Initialization script (.vbs file): It
launches qtp tool and calls driver script, at end it closes qtp tool.
2)
Driver script (QTP Script file): It is only
the qtp script, we can associate all resources to this script
