// Make sure the widget renders the scene, and store it in a QImage.
widget.raise();
widget.repaint();
// Run the application for a while, and then quit so we can save an image.

// Set up the image regression test.
ImageRegressionTest test(argc, argv);
// Do the image threshold test, printing output to the std::cout for ctest.
return test.imageThresholdTest(image, std::cout);
