Threaded test execution

Hi,   I'm testing an application where exceptions are caught, then handled in a separate application with a more user-friendly bubble pop-up.  We have code that will detect the presence of a the ex...

If you want to have a function/routine running on an interval checking for the pop-up every few seconds, you could use a Timer object.  Check out https://support.smartbear.com/testcomplete/docs/scripting/timers.html for info.

Note, however, that according to that document, if this pop-up is seen as an "unexpected window", the timer will not execute it's routine.

So, that is actually another way of doing things.  There is an event handler for "OnUnexpectedWindow" as well as "OnOverlappingWindow".  you could treat that pop-up as one of these.  So, check out https://support.smartbear.com/testcomplete/docs/testing-with/running/handling-errors/unexpected-windows.html

Ah, thanks Robert, very useful!

 

It seems like neither solution gives the flexibility of actual threaded execution (unexpected windows only triggers when the script performs actions, timers halt all test execution until the check is complete), but it's probably about as close as we're likely to get i think - i'll experiment with combinations of these two and see how it goes.

 

Thanks for the help!

Chris.

    Well, by "halt" all execution, as long as your routine in your timer is pretty quick, it is relatively quick.  Keep your timer routine to a quick check of "does the window exist RIGHT NOW (WaitAliasChild with the timeout parameter set to 0)? If so, click a button" Fire that off every 10 seconds or so and you probably won't even notice that it's running.

    In any case, these are scripted tests using an interpreted language... there's no multi-threading.  Using the built in event handlers or using a Timer are probably the best you're going to get.

      Python supports threading out of the box. It's one of it's built in modules. But I have no idea if it works within TC. I've only ever used it in standalone Python. (Where it works very well)

        From the help topic Python - Specifics of Usage:

        Python - Specifics of Usage

        Multithreading

        Though TestComplete’s Python library includes the threading module, TestComplete does not support multithreaded Python scripts. Code in the threads that you create will not work. Calls to TestComplete objects, methods and properties from these threads will cause an exception.

        So, you could probably call what TC has "PythonScript" just like the Delphi programming language supports threads, DelphiScript does not.
