MutPy

MutPy is a Python mutation testing framework that can be used jointly with the UNITTEST, PYTEST, and NOSETEST frameworks.

MutPy can mutate Python source code files using different mutation operators, such as arithmetic, bitwise, boolean, comparison, exception handling, logical, and unary operators.

The framework also enables higher-order mutation testing, which involves applying multiple mutations to the same code element.

MutPy produces text and XML reports that show the mutation score and the details of each mutant.
