Test modal dialog with Qt Test

Question

I am trying to write a unit test for a GUI application using the QTestLib. The problem is that one of the slots creates a modal dialog using exec() and I found

Answer 1

The solution I use in command line applications which use Qt libraries meant for GUIs is the singleShot, as this answer alludes. In those cases it looks like this:

QCoreApplication app(argc, argv);

// ...

QTimer::singleShot(0, &app, SLOT(quit()));
return app.exec();

So in your case I imagine it would look something like this:

QDialog * p_modalDialog = getThePointer(); // you will have to replace this with
                                           // a real way of getting the pointer

QTimer::singleShot(0, p_modalDialog, SLOT(accept()));

p_modalDialog->exec(); // called somewhere else in your case
                       // but it will be automatically accepted.
