Some Useful Tips with QTP

We Sharing some of the useful tips on quick test professional. I used while working and found from gds. I urge the readers to share their experiences/tips they have used while working on QTP. You can use the comments section to do the same.

1) How to add a constant number in a datatable?
This is more to do with MS excel then QTP!! but useful to know because at times it becomes frustrating to the novices.
Just append ‘ to the number
Ex: if you wish to enter 1234567 in datatable then write it as ‘1234567

2) How can i check if a parameter exists in DataTable or not?
The best way would be to use the below code:
on error resume next
val=DataTable(”ParamName”,dtGlobalSheet)
if err.number<> 0 then
‘Parameter does not exist
else
‘Parameter exists
end if

3) How can i check if a checkpoint passes or not?
chk_PassFail = Browser(…).Page(…).WebEdit(…).Check (Checkpoint(”Check1″))
if chk_PassFail then
MsgBox “Check Point passed”
else MsgBox “Check Point failed”
end if

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

5) What is the difference between an Action and a function?
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.

6) Where to use function or action?
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.

7) When to use a Recovery Scenario and when to us on error resume next?
Recovery scenarios are used when you cannot predict at what step the error can occur or when you know that error won’t occur in your QTP script but could occur in the world outside QTP, again the example would be “out of paper”, as this error is caused by printer device driver. “On error resume next” should be used when you know if an error is expected and dont want to raise it, you may want to have different actions depending upon the error that occurred. Use err.number & err.description to get more details about the error.

8) How to use environment variable?
A simple defintion could be… it is a variable which can be used across the reusable actions and is not limited to one reusable action.
There are two types of environment variables:
1. User-defined
2. Built-in
We can retrieve the value of any environment variable. But we can set the value of only user-defined environment variables.

To set the value of a user-defined environment variable:
Environment (VariableName) = NewValue

To retrieve the value of a loaded environment variable:
CurrValue = Environment (VariableName)

Example
The following example creates a new internal user-defined variable named MyVariable with a value of 10, and then retrieves the variable value and stores it in the MyValue variable.

Environment.Value(”MyVariable“)=10
MyValue=Environment.Value(”MyVariable“)

9) What are the files and subfolders of a QuickTest Professional test?
The files and folders hold binary and text data that are required for the test to run successfully.
The following table provides a description, the type, and comments regarding the files that make up a QuickTest Professional test.

10) How to rename a checkpoint (QTP 9.0)?
Example:
Window(”Notepad”).WinEditor(”Edit”).Check CheckPoint(”Edit”)
In the above example, the user would like to change the name of the CheckPoint object from “Edit” to something more meaningful.
Note:
This functionality is new to QuickTest Professional 9.0.This is not available for QTP 8.2 and below.
1. Right-click on the Checkpoint step in the Keyword View or on the Checkpoint object in Expert View.
2. Select “Checkpoint Properties” from the pop-up menu.
3. In the Name field, enter the new checkpoint name.
4. Click . The name of the checkpoint object will be updated within the script.
Example:
Window(”Notepad”).WinEditor(”Edit”).Check CheckPoint(”NewCheckPointName”)
Note:
You must use the QuickTest Professional user interface to change the name of the checkpoint. If you manually change the name of the checkpoint in the script, QuickTest Professional will generate an error during replay. The error message will be similar to the following:

“The “” CheckPoint object was not found in the Object Repository. Check the Object Repository to confirm that the object exists or to find the correct name for the object.”

The CheckPoint object is not a visible object within the object repository, so if you manually modify the name, you may need to recreate the checkpoint to resolve the error.

11) Does QuickTest Professional support Internet Explorer 7.0?

[NoBBTApps]
wmplayer.exe=rek
