How to run qtestlib unit tests from QtCreator

I am developing a GUI application in Qt Creator and want to write some unit tests for it.

I followed This guide to make some unit tests with QtTestlib and the program compiles fine. But how do I run them? I would like them to be run before the GUI app starts if debug buid and not run if release build.

Solution

  • Finally figured out how to run tests before starting the app.

    I added one static method in the tests class to run the tests:

    #include <QtTest/QtTest>

TestClass::runTests()
{
    TestClass * test = new TestClass();

    QTest::qExec(test);
    delete test;
}

    In the main function, do:

    int main(int argv, char *args[])
{
    ::TestsClas::runTests();

    QApplication app(argv, args);
    MainWindow mainWindow;
    mainWindow.setGeometry(100, 100, 800, 500);
    mainWindow.show();

    return app.exec();
}

    The test results are printed in application output window.
