selects tests affected by changed files and methods

Project description


This is a fork of pytest-testmon that adds functionality to ignore changes to libraries used by the code. The standard version of pytest-testmon looks not only at the python code for changes, but also versions of dependencies. This makes it unsuitable for sharing among developers (who may have a different local set of dependencies), or CI/CD systems where your local, staging and production environments may differ in the number and versions of dependencies used.

From the original repo:

This is a pytest plug-in which automatically selects and re-executes only tests affected by recent changes. How is this possible in dynamic language like Python and how reliable is it? Read here: Determining affected tests


pip install pytest-testmon-skip-libraries

# build the dependency database and save it to .testmondata
pytest --testmon

# change some of your code (with test coverage)

# only run tests affected by recent changes
pytest --testmon

# only run tests affected by recent changes while ignoring changes
# to any libraries used by the code
pytest --testmon --skip-libraries
