Unit Testing with GTest

Fleshbits

The company I am writing code for uses GTest in their CI/CD. I'd really rather not bring in QTest if at all possible.

However, GTest requires you to run their test runner on the main thread:

int main(int argc, char* argv[])

{
    ::testing::InitGoogleTest(&argc, argv);
    return RUN_ALL_TESTS();
}

So does Qt Application, which seems necessary for everything in Qt, even the websocket code I want to test.

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    // SNIP
    
    EchoServer *server = new EchoServer(port, debug);
    QObject::connect(server, &EchoServer::closed, &a, &QCoreApplication::quit);

    return a.exec();
}

So, how would I go about testing the class I made based on the echo sever example
https://code.qt.io/cgit/qt/qtwebsockets.git/tree/examples/websockets/echoserver?h=5.14

in Gtest?

I've even tried using the wizard in Creator according to the instructions at:
https://doc.qt.io/qtcreator/creator-autotest.html
and the code it generates also does not start a QApplication, so anything that needs QApplication running cannot be tested, unless I am missing something.
