pytest-involve 0.1.3

Usages

pytest-involve adds one command line argument to pytest, namely --involving. This can be provided a file path, a module import path (such as you would use in a Python interpreter), or either of the above suffixed with :: and the name of something defined in there:

pytest --involving ./path/to/file.py

pytest --involving importable.module.path

pytest --involving ./path/to/file.py::member

pytest --involving importable.module.path::member

This will have the effect of only collecting and running tests which are defined in modules whose imports overlap with the file(s) and member(s) specified with the --involving flag.

The plugin aims for recall over precision: It might run a few tests that aren’t strictly necessary, but it shouldn’t ignore any tests that are.

The ::member syntax will only work for things with a __file__ attribute (so, mostly classes and functions).

pytest-involve should play nicely with most other pytest plugins and command line tooling. One useful example is as follows:

git status -s | cut -c4- | grep .py | sed "s/^/--involving /" | xargs pytest

This will take all *.py files mentioned in the output of git status and provide them to pytest prefixed with --involving, which allows for quickly running unit tests relevant to the current state of the repository.

This pytest plugin was generated with Cookiecutter along with @hackebrot’s cookiecutter-pytest-plugin template.
