11.Keyword view in QTP is also termed as

Icon based view

12.What is the use of data table in QTP?

parameterizing the test

13.What is the use of working with actions?

To design a modular and efficient tests

14.What is the file extension of the code file and object repository file in QTP?

The extension for code file is .vbs and the extension for object repository is .tsr

15.What are the properties we can use for identifying a browser and page when using descriptive programming?

The name property is used to identify the browser and the title property is used to identify the page

16.What are the different scripting languages we can use when working with QTP?

VB script

17.Give the example where we can use a COM interface in our QTP project?

COM interface appears in the scenario of front end and back end.

18.Explain the keyword createobject with example

createobject is used to create and return a reference to an automation object.

For example:
Dim ExcelSheetSet
ExcelSheet=createobject(“Excel.Sheet”)

19.How to open excel sheet using QTP script?

You can open excel in QTP by using the following command
System.Util.Run”Path of the file”

20.Is it necessary to learn VB script to work with QTP?

Its not mandate that one should mastered in VB script to work with QTP. It is mostly user friendly and for good results we need to have basic VB or concepts which will suffice

21.If WinRunner and QTP both are functional testing tools from the same company. Why a separate tool QTP came in to picture?

QTP has some additional functionality which is not present in WinRunner. For example,you can test(Functionality and Regression testing) an application developed in .Net technology with QTP,which is not possible to test in WinRunner

22.Explain in brief about the QTP automation object model

The test object model is a large set of object types or classes that QTP uses to represent the objects in our application. Each test object has a list of properties that can uniquely identify objects of that class

23.What is a Run-Time data table?

The test results tree also includes the table-shaped icon that displays the run-time data table-a table that shows the values used to run a test containing data table parameters or the data table output values retrieved from a application under test

24.What are all the components of QTP test script?

QTP test script is a combination of VB script statements and statements that use QuickTest test objects ,methods and properties

25. What is test object?

Its an object that QTP uses to represent an object in our application. Each test object has one or more methods and properties that we can use to perform operations and retrieve values for that object. Each object also has a number of identification properties that can describe the object.

26.What are all the rules and guidelines want to be followed while working in expert view?

Case-sensitivity

VB script is not case sensitive and does not differentiate between upper case and lower case spelling of words.

Text strings

When we enter value as a string, that time we must add quotation marks before and after the string

Variables

We can use variables to store strings,integers,arrays and objects. Using variables helps to make our script more readable and flexible.

Parentheses

To achieve the desired result and to avoid the errors,it is important that we use parentheses() correctly in our statements.

Comments

We can add comments to our statements using apostrophe(’),either at a beginning of the separate line or at the end of a statement

Spaces

We can add extra blank spaces to our script to improve clarity. These spaces are ignored by the VB script

code:

Const adOpenStatic = 3
Const adLockOptimistic = 3
Const adUseClient = 3
Set objConnection = CreateObject(”ADODB.Connection”)
Set objRecordset = CreateObject(”ADODB.Recordset”)
objConnection.Open “DRIVER={Microsoft ODBC for Oracle};UID=;PWD=
”
objRecordset.CursorLocation = adUseClient
objRecordset.CursorType = adopenstatic
objRecordset.LockType = adlockoptimistic
ObjRecordset.Source=”select field1,field2 from testTable”
ObjRecordset.ActiveConnection=ObjConnection
ObjRecordset.Open ‘This will execute your Query
If ObjRecordset.recordcount>0 then
Field1 = ObjRecordset(”Field1″).Value
Field2 = ObjRecordset(”Field2″).Value
End if

How can i check if a environment variable exist or not?

admin — Sat, 02 Jun 2007 18:27:28 +0000

When we use Environment(”Param1″).value then QTP expects the environment variable to be already defined. But when we use Environment.value(”Param1″) then QTP will create a new internal environment variable if it does not exists already. So to be sure that variable exist in the environment try using Environment(”Param1″).value.

My test fails due to checkpoint failing, Can i validate a checkpoint without my test failing due to checpoint failure?

admin — Sat, 02 Jun 2007 18:26:43 +0000

code:
Reporter.Filter = rfDisableAll ‘Disables all the reporting stuff
chk_PassFail = Browser(…).Page(…).WebEdit(…).Check (Checkpoint(”Check1″))
Reporter.Filter = rfEnableAll ‘Enable all the reporting stuff
if chk_PassFail then
MsgBox “Check Point passed”
else
MsgBox “Check Point failed”
end if

How can i check if a checkpoint passes or not?

admin — Sat, 02 Jun 2007 18:26:14 +0000

code:
chk_PassFail = Browser(…).Page(…).WebEdit(…).Check (Checkpoint(”Check1″))
if chk_PassFail then
MsgBox “Check Point passed”
else
MsgBox “Check Point failed”
end if

What’s the difference between a checkpoint and output value?

admin — Sat, 02 Jun 2007 18:25:36 +0000

Checkpoint only checks for the specific attribute of an object in AUT while Output value can output those attributes value to a column in data table.

What is checkpoint?

admin — Sat, 02 Jun 2007 18:25:13 +0000

Checkpoint is basically a point in the test which validates for truthfulness of a specific things in the AUT. There are different types of checkpoints depending on the type of data that needs to be tested in the AUT. It can be text, image/bitmap, attributes, XML etc….

Where to use function or action?

admin — Sat, 02 Jun 2007 18:24:10 +0000

Well answer depends on the scenario. If you want to use the OR feature then you have to go for Action only. If the functionality is not about any automation script i.e. a function like getting a string between to specific characters, now this is something not specific to QTP and can be done on pure VB Script, so this should be done in a function and not an action. Code specific to QTP can also be put into an function using DP. Decision of using function/action depends on what any one would be comfortable using in a given situation.

What is the difference between an Action and a function?

admin — Sat, 02 Jun 2007 18:23:33 +0000

Action is a thing specific to QTP while functions are a generic thing which is a feature of VB Scripting. Action can have a object repository associated with it while a function can’t. A function is just lines of code with some/none parameters and a single return value while an action can have more than one output parameters.

Can i change properties of a run time object?

admin — Sat, 02 Jun 2007 18:22:56 +0000

No (but Yes also). You can use GetROProperty(”outerText”) to get the outerText of a object but there is no function like SetROProperty to change this property. But you can use WebElement().object.outerText=”Something” to change the property.
