pytest-filemarker

A pytest plugin that runs marked tests when files change.

Usage

Files should have a PYTEST_MARKS variable containing a list of marked tests to run when the files change.

PYTEST_MARKS = ['markone', 'marktwo']

class MyClass:
    ...

When this file has changed, any tests with marks markone or marktwo will be run.

To invoke the plugin, run:

pytest --filemarker-active

By default, the plugin will use git to look at the changes between HEAD and HEAD~1 to generate a list of files to inspect. To override this, use the --filemarker-files parameter:

pytest --filemarker-files=FILE1,FILE2

Options

filemarker:
  --filemarker-active   Should the plugin be active? Automatically set to True
                        if other options are specified.
  --filemarker-files=FILE1,FILE2
                        Files to search. If not supplied will look at the latest
                        changes from git.
  --filemarker-variable=VARIABLE
                        Variable which contains a list of marks. Defaults to
                        PYTEST_MARKS

filemarker-variable can also be set wherever you configure pytest (e.g. pytest.ini).
