Ans: It is used for Error Handling.

In vbscript, the related code is -ON ERROR RESUME NEXT. By creating Recovery Scenarios, we can handle error. But, in Real-time 90% people don't use These Reco.Scenarios.

Instead they use VBScript to take the error, and then write the Discrepancy into an xls file.

Ans: This is default behavior.

Ans: Returns a copy of a string without leading spaces (LTrim),

Trailing spaces (RTrim), or both leading and trailing

Spaces (Trim).

LTrim (string)

RTrim (string)

Trim (string)

The string argument is any valid string expression. If

String contains Null, Null is returned.

Remarks

The following example uses the LTrim, RTrim, and Trim

Functions to trim leading spaces, trailing spaces, and both

Leading and trailing spaces, respectively:

Dim MyVar

MyVar = LTrim ("   vbscript ")   ' MyVar

Contains "vbscript ".

MyVar = RTrim ("   vbscript ")   ' MyVar contains”  

Vbscript".

MyVar = Trim ("   vbscript ")   ' MyVar contains "vbscript".

Ans: The InStr function returns the position of the first

Occurrence of one string within another.

Example: Dim txt, pos

      txt="This is a beautiful day!"

      Pos=InStr (txt,"his")

      Document. Write (pos).

Ans: Inserting a call to action will only import the columns of the action called.

Ans: Mercury has determined that 1.4MB is the maximum size of XML file that QTP  can handle.

Ans: SetTOProperty changes the property values used to identify an object during the test run.

Ans: By default it creates an “XML” file and displays the result.

Ans: when you test application, you may want to check how it performs the same operations with multiple sets of data. For example suppose you want to check how your application responds to ten separate sets of data. You could record ten separate tests, each with its own set of data. Alternatively, you can create a parameterized test that runs ten times: each time the test runs, it uses a different set of data.

Ans: “window1” and then while running its “window2” in this case how does QTP handles,
QTP handles those situations “Regular Expressions”
