``pytest-involve`` is a ``pytest`` plugin for running only tests which cover a given file
or set of files. It's called ``pytest-involve`` because it lets you run only tests involving
modules or members from those modules.

Usually with ``pytest`` the test set to run is specified and coverage collected based on that set. When ``pytest-involve``
is used, instead you specify the file(s) you want to cover, and test files are selected based
on whether they import from those file(s) or not.

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.
