Question - Can we call QTP test from another test using scripting. Suppose there are 4 tests and I want to call these tests in a main script. Is this possible in QTP? 
          
        
        Answer - 
        
Yes. You can call 4 or even more scripts in your tests.For this, first you will need to make the Actions in the corresponding scripts re-usable.Then from the destination script you can make calls to these re-usable actions.
