Steps to Call Function from QTP

This post is about how to call Function from QTP.

Function:-Its a block of statements that perform a particular task.

Open a notepad and paste the code shown below.

Function f1
msgbox "hiii"
msgbox "function demo "
End Function

and save it as abc.vbs

.vbs is extension for vb script files.

f1 is function name and abc is file name.

Now open a new test and associate the function to new test as shown below

Navigation for associating is:-

1.Click menu item Test.
2.Select option Settings(U can see a window named Test Settings).
3.Click on Resources Tab(U can see + symbol which is used to add a new file to test).
4.Click on + symbol and browse the desired file(here abc.vbs).
U can see ur file path in Associated library files
5.Now click on Ok button.

Note:-This navigation is for QTP 8.2

Now its time to call function just write function name in test and run.

In this way u can call functions wherever required in ur script.
