Testing QApplication descendant with QTestLib

[Oleg]

Hello,

I'm trying to figure out how to use QTestLib with custom QApplication. So, I want to test if my command line aruments are handled correctly, for example language is set to the specified one (i.e. --set-lang=de). All the logic is placed in Application::exec().

So, the question is how to run Application::exec() from my test. Then I'd like to create MainWindow and access any label within it to test its text.

Thanks.
