pytest-xdist 3.8.0 (2025-06-30)

Features

• [#1083](https://github.com/pytest-dev/pytest-xdist/issues/1083) <https://github.com/pytest-dev/pytest-xdist/issues/1083>_: Add --no-loadscope-reorder and --loadscope-reorder option to control whether to automatically reorder tests in loadscope for tests where relative ordering matters. This only applies when using loadscope.

  For example, [test_file_1, test_file_2, ..., test_file_n] are given as input test files, if --no-loadscope-reorder is used, for either worker, the test_file_a will be executed before test_file_b only if a < b.

  The default behavior is to reorder the tests to maximize the number of tests that can be executed in parallel.

pytest-xdist 3.7.0 (2025-05-26)

Features

• [#1142](https://github.com/pytest-dev/pytest-xdist/issues/1142) <https://github.com/pytest-dev/pytest-xdist/issues/1142>_: Added support for Python 3.13.

• [#1144](https://github.com/pytest-dev/pytest-xdist/issues/1144) <https://github.com/pytest-dev/pytest-xdist/issues/1144>_: The internal steal command is now atomic - it unschedules either all requested tests or none.

  This is a prerequisite for group/scope support in the worksteal scheduler, so test groups won't be broken up incorrectly.

• [#1170](https://github.com/pytest-dev/pytest-xdist/issues/1170) <https://github.com/pytest-dev/pytest-xdist/issues/1170>_: Add the --px arg to create proxy gateways.

  Proxy gateways are passed to additional gateways using the via keyword. They can serve as a way to run multiple workers on remote machines.

• [#1200](https://github.com/pytest-dev/pytest-xdist/issues/1200) <https://github.com/pytest-dev/pytest-xdist/issues/1200>_: Now multiple xdist_group markers are considered when assigning tests to groups (order does not matter).

  Previously, only the last marker would assign a test to a group, but now if a test has multiple xdist_group marks applied (for example via parametrization or via fixtures), they are merged to make a new group.

Removals

• [#1162](https://github.com/pytest-dev/pytest-xdist/issues/1162) <https://github.com/pytest-dev/pytest-xdist/issues/1162>_: Dropped support for EOL Python 3.8.

Trivial Changes

• [#1092](https://github.com/pytest-dev/pytest-xdist/issues/1092) <https://github.com/pytest-dev/pytest-xdist/issues/1092>_: Update an error message to better indicate where users should go for more information.

• [#1190](https://github.com/pytest-dev/pytest-xdist/issues/1190) <https://github.com/pytest-dev/pytest-xdist/issues/1190>_: Switched to using a SPDX license identifier introduced in PEP 639.
