Unit Test: Test if QPushButton has a menu

[FelixB]

Hello,

I have a GUI with lots of buttons. Each button should show a menu when clicked. I want to test this behaviour in the following unit test:

BOOST_AUTO_TEST_CASE(EachButtonHasMenuOnClick)
  {
    BOOST_FOREACH(QPushButton* elButton, m_perilib.findChildren<QPushButton*>())
    {
      // click on button
      QTest::mouseClick( elButton, Qt::LeftButton );
 
      // check if menu is visible
      QMenu* elButtonMenu = elButton->menu();
      BOOST_REQUIRE(elButtonMenu);
      BOOST_CHECK_EQUAL(true, elButtonMenu->isVisible());
 
      // click again (somewhere outside the menu) to close menu
      QTest::mouseClick( elButton, Qt::LeftButton );
      BOOST_CHECK_EQUAL(false, elButtonMenu->isVisible());
    }
  }

BOOST_AUTO_TEST_CASE(EachButtonHasMenuOnClick)
  {
    BOOST_FOREACH(QPushButton* elButton, m_perilib.findChildren<QPushButton*>())
    {
      // click on button
      QTest::mouseClick( elButton, Qt::LeftButton );

      // check if menu is visible
      QMenu* elButtonMenu = elButton->menu();
      BOOST_REQUIRE(elButtonMenu);
      BOOST_CHECK_EQUAL(true, elButtonMenu->isVisible());

      // click again (somewhere outside the menu) to close menu
      QTest::mouseClick( elButton, Qt::LeftButton );
      BOOST_CHECK_EQUAL(false, elButtonMenu->isVisible());
    }
  }

To copy to clipboard, switch view to plain text mode 

But the problem is: the menu is opened modal, so QTest::mouseClick does not return until the user closes the menu by clicking anywhere. That is quite bad for an automated unit test... Is there any simple solution? Or do I have to use a different thread?

thx!
