How to test Qt application with Boost Unit Test framework

Question

Is it possible to write unit tests for Qt application for example QCoreApplication to test it's functions that are invoked in arbitrary time? Let's suppose that I want to test member function of my class like

void deleteConnectionFromList(QTcpSocket*); 

This function should be called after other functions like addNewSocket()

But where should I put BOOST_CHECK_EQUAL() statement?

BOOST_AUTO_TEST_CASE( test )
{

  int argc{};
  QCoreApplication app(argc, nullptr);
  Server server;
  app.exec();

}

Answer 1

I needed to use boost unit test with Qt Network classes (which required event loop). What I did is something like that.

BOOST_AUTO_TEST_CASE(createServerNetwork)
{
QCoreApplication app(boost::unit_test::framework::master_test_suite().argc,
                     boost::unit_test::framework::master_test_suite().argv);

std::thread thread_server( [&](void)
{
[...]//your code here
QCoreApplication::quit();
});

BOOST_CHECK(app.exec() == 0);
thread_server.join();
}
