SFML/C++ Simulating user input

Question

I'm trying to write some unit test methods. I want to test method which checks if key is pressed or released. And here is my question:

Is it possible in SFML with C++ to simulate random key press on keyboard?

Or I will just have to trust myself that this works?

Answer 1

The internals of sf::Keyboard::isKeyPressed would make simulation difficult, but if you are looking to simulate KeyPressed or KeyReleased events I'm pretty sure the following should work:

const sf::Event simulateKeypress(sf::Keyboard::Key key, bool alt, bool control, bool shift, bool system)
{
    sf::Event::KeyEvent data;
    data.code = key;
    data.alt = alt;
    data.control = control;
    data.shift = shift;
    data.system = system;

    sf::Event event;
    event.type = sf::Event::KeyPressed;
    event.key = data;
    return event;
}

//your handler here
handleEvent(simulateKeypress(sf::Keyboard::Key::A, false, false, false, false));

I'm unable to test this at the moment... If it works, then you should be able to make similar functions for other events.
