Problem with QTest and QApplication

[wysota]

Yes, this is the correct behaviour.

But then how do you write a unit test (in python) for this?

[wysota]

You need a running event loop. The language doesn't matter here. The code you posted has an incorrect construction in the first place, read the docs for QTestLib --- you need a class inheriting QObject and you need to impement each test as a private slot of that class.

[aquavitae]

I see that from Qt's docs, but it isn't really clear from the PyQt4 docs, which imply that python's unittest framework should be used rather that Qt's QTestLib. Also, PyQt4 doesn't provide QTest::qExec(). Maybe I just need another cup of coffee, but it looks like the language does matter in this case...

[wysota]

If PyQt doesn't provide qExec then you simply can't use the framework or you need to provide your own wrapper to qExec.
