FWIW, I've had some progress (after having a number of hilarious potholes).
@pytest.fixture(autouse=True) def mock_window(monkeypatch): sys.is_pyglet_docgen = True monkeypatch.setattr('pyglet.window.Window', MockWindow) from arcade import Window return Window As long as I ask for this fixture in my tests and don't import anything that might import pyglet in the tests, it works and uses my own MockWindow in the place of pyglet.window.Window. My tests are going pretty fast now. -- You received this message because you are subscribed to the Google Groups "pyglet-users" group.
