pytest support for PyQt and PySide applications

Project description

pytest-qt is a pytest plugin that allows programmers to write tests for PySide, PySide2 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(widget.button_greet, QtCore.Qt.LeftButton)

    assert widget.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.

Features

Requirements

Works with either PySide, PySide2 or PyQt (PyQt5 and PyQt4) picking whichever is available on the system, giving preference to the first one installed in this order:

  • PySide2
  • PyQt5
  • PySide
  • PyQt4

To force a particular API, set the configuration variable qt_api in your pytest.ini file to pyqt5, pyside, pyside2, pyqt4 or pyqt4v2. pyqt4v2 sets the PyQt4 API to version 2.

[pytest]
qt_api=pyqt5

Alternatively, you can set the PYTEST_QT_API environment variable to the same values described above (the environment variable wins over the configuration if both are set).

Change Log

Please consult the changelog page.

Bugs/Requests

Please report any issues or feature requests in the issue tracker.

Contributing

Contributions are welcome, so feel free to submit a bug or feature request.

Pull requests are highly appreciated! If you can, include some tests that exercise the new code or test that a bug has been fixed, and make sure to include yourself in the contributors list. :)

Running tests

Tests are run using tox. It is recommended to develop locally on Python 3 because PyQt5 and PySide2 are easily installable using pip:

$ tox -e py37-pyside2,py37-pyqt5

pytest-qt is formatted using black and uses pre-commit for linting checks before commits. You can install pre-commit locally with:

$ pip install pre-commit
$ pre-commit install
