We wrote a test case, TestJsonSerializer, with some test functions. We need a main() function in our drum-machine-test application. We will explore three possibilities:

  • The QTEST_MAIN() function
  • Write our own simple main() function
  • Write our own enhanced main() supporting multiple test classes

The QTest module provides an interesting macro, QTEST_MAIN(). This macro generates a complete main() function for your application. This generated method runs all the test functions of your test case. To use it, add the following snippet at the end of the TestJsonSerializer.cpp file:
