Both PySide and PyQt allow rapid prototyping and development of Qt applications using the Python programming language. However, the Qt Test framework is focused on C++, and only a subset of its functionality is available in Python. Together with the “unittest” module in the Python standard library (which exposes a heavyweight, xUnit-like API), this can make tests unnecessarily cumbersome to write. The pytest framework coupled with the pytest-qt plugin allows writing tests for Qt/Python code in a much more straightforward and fun way. It exposes the QTestLib API, but also adds various high-level functionality with an API which is more suitable for Python code. This talk will give the audience a short introduction to pytest and explain how to test Python/Qt code using the pytest-qt plugin. It will also take a quick look at other useful pytest plugins which can be combined with pytest-qt.
