Installation

pip install xdist-scheduling-exclusive pytest-xdist

Usage

To integrate with your pytest setup, update conftest.py as follows:

from xdist_scheduling_exclusive import ExclusiveLoadScopeScheduling

def pytest_xdist_make_scheduler(config, log):
    """xdist-pytest hook to set scheduler."""
    return ExclusiveLoadScopeScheduling(config, log)

Available Schedulers:

• ExclusiveLoadScheduling Schedule tests from exclusive_tests.txt first and on dedicated nodes.
• ExclusiveLoadFileScheduling: Place tests from exclusive_tests.txt to unique scopes. Other tests are grouped as in --dist loadfile: tests from the same file run on the same node.
• ExclusiveLoadScopeScheduling: Schedule tests from exclusive_tests.txt first and on dedicated nodes. Other tests are grouped as in --dist loadfile: tests from the same file run on the same node.

Optimizing for Long-Running Tests:

To identify long-running tests for the exclusive list, utilize pytest's --durations option to sort tests by execution time.

Developers

Do not forget to run . ./activate.sh.

To see how tests were scheduled use something like
