QTP Interview question 34: Explain the difference between VBScript function and VBScript subroutine?

Advanced QTP interview questions may examine not only various aspects of QA tester's hands-on experience with HP QTP, but how deep the interviewee knows VBScript - HP Quick Test Professional scripting language. The candidate for QTP QA tester position should be familiar with VBScript variables and arrays, able to explain the difference between VBScript function and VBScript subroutine and for some high level test position show the real life experience working with VBScript classess.

VBScript subroutine is a series of statements, enclosed by the Sub and End Sub statements, can perform actions, but does not return a value, can take arguments and without arguments, it should include an empty set of parentheses.

VBScript function is a series of statements, enclosed by the Function and End Function statements, can perform actions and can return a value, can take arguments that are passed to it by a calling procedure, without arguments should include an empty set of parentheses and returns a value by assigning a value to its name.

The major difference between VBScript function and a subroutine, is that a function can return a value back to where it was called from.

QTP Interview Question 33: Do you know any error messages of QTP license server?

Computers running QuickTest Pro using a concurrent license must always be able to access the QTP concurrent license server. If your HP QTP instance is not able to start and displays "Cannot talk to the license manager. "LocalHost" server not running", it means that your QuickTest Pro concurrent license server is down. Launch services.msc from the Run option on the Start Menu. Locate the Sentinel LM service and click Start.

QTP Interview Question 32: How to use HP QTP 10 in agile testing?

I suppose there is no doubt that certain agile manifesto principles, such as “welcome changing requirements, even late in development” or “deliver working software frequently, from a couple of weeks to a couple of months, with a preference to the shorter timescale” would make smart QTP test automation engineer wince. Does it mean Quick Test Pro that automated script for complicated business requirement created yesterday won't work tomorrow or test automation engineer would have less time to develop HP QTP 10 scripts which can transform as often as requirement? Fortunately HP QTP works very well in agile environment. The agile development creates new functionality every round, and this requires automated regression testing. The automation test engineer has to work in parallel with development team on automated tests. The crucial point for successful execution of HP QTP scripts is making sure that the developers name all object, one more helpful approach is to set up continuous daily builds and execute the scripts to make sure that the new software didn't shatter any QTP 10 scripts.
