pytest-qt is a pytest plugin that allows programmers to write tests for PySide and PyQt applications.

The main usage is to use the qtbot fixture, responsible for handling qApp creation as needed and provides methods to simulate user interaction, like key presses and mouse clicks:

def test_hello(qtbot):
    widget = HelloWidget()
    qtbot.addWidget(widget)

    # click in the Greet button and make sure it updates the appropriate label
    qtbot.mouseClick(window.button_greet, QtCore.Qt.LeftButton)

    assert window.greet_label.text() == 'Hello!'

This allows you to test and make sure your view layer is behaving the way you expect after each code change.

Python 2.6 or later, including Python 3+.

Works with either PySide, PyQt (PyQt4 and PyQt5) picking whichever is available on the system, giving preference to the first one installed in this order:

• PySide
• PyQt4
• PyQt5

To force a particular API, set the environment variable PYTEST_QT_API to pyside, pyqt4 or pyqt5.
