QVERIFY and QCOMPARE macros can only be used in functions returning void; In more complex test cases a test might want to use these macros also in non void functions.

See for example this test: https://codereview.qt-project.org/#/c/153336/22/tests/auto/qx11info/tst_qx11info.cpp

It would be nice if we could set arbitrary "exit functions" for macros , e.g. "return;" (default), "return false", "close()" (as in QWindow);

This missing feature becomes more important now with an introduction of lambdas in C++: In the same example code, instead of writing :

obj->m_foundFirstEventAgain = true;

It would be cleaner just to add QFAIL macro there, that calls QWindow::close();

This would need to be looked at properly, maybe there are better alternatives to macros.
