A pytest plugin to add markers based on fixtures used.


This plugin allows you to selectively run tests that require a certain fixture. This comes in handy if you’re refactoring fixtures.


You can install “pytest-fixture-marker” via pip from PyPI:

$ pip install pytest-fixture-marker


Once installed, the plugin will automatically mark each test. Marker names are generated from the fixture names.

$ # run all tests that use the tempdir fixture
$ pytest -m fixture_tempdir

If you’re not happy with the marker name convention of adding a fixture_ prefix, you can configure it by setting fixture_marker_expression in pytest.ini (or tox.ini or setup.cfg), or by passing the –fixture-marker-expression argument. If both are specified the argument takes priority.

The fixture marker expression must be a format string that will be filled with one positional argument: the fixture name.

$ # use custom marker naming expression
$ pytest -m foobar_tempdir --fixture-marker-expression=foobar_{}


Contributions are very welcome. Tests can be run with tox, please ensure the coverage at least stays the same before you submit a pull request.


Distributed under the terms of the MIT license, “pytest-fixture-marker” is free and open source software


If you encounter any problems, please file an issue along with a detailed description.
