Available as part of the Tidelift Subscription. The test cases are executed in serial order and assert is issued on an execution of the test cases. In order to run the tests in parallel, do this: When giving a teaching/practice assignment with pre-written tests, either all tests can be given at once (leaving students overwhelmed and unsure which failures should be fixed next), or piece-wise (in individual files -- which becomes a mess for larger projects). Those markers can be used by plugins, and also pytest. Currently the groupings can’t be customized, with grouping by class takes priority over grouping by module.

All tests that use the serial fixture are executed serially while any tests that do not use the fixture are executed in parallel. If many tests in the series depend on a single test, it might be an option, to move the call to pytest_dependency.depends() in a fixture on its own. . The @pytest.mark.parametrize decorator enables the parameterization of arguments for a test function.
