By default, the -n option will send pending tests to any worker that is available, without any guaranteed order, but you can control this with these options: --dist=loadscope: tests will be grouped by module for test functions and by class for test methods, then each group will be sent to an available worker, guaranteeing that all tests in a group run in the same process.

Made warmup_iterations available as a marker argument (eg: @pytest.mark.benchmark(warmup_iterations=1234)). Have a question about this project? It didn't matter to me in what order they were executed as long as they weren't executed at the same time. . xfail - produce an “expected failure” outcome if a certain condition is met To run the marked tests, we can use the following syntax: pytest -m -v -m represents the marker name of the tests to be executed. Writing code with testing in mind from the start can make testing significantly easier. We can do this by using the following marker −. pytest_configure hook: Registered marks appear in pytestâs help text and do not emit warnings (see the next section). gpaw.test.conftest.gpw_files (request, tmp_path_factory) [source] ¶ Reuse gpw-files.
