Refs #36936 - Adjusted tests to set PYTHON_COLORS environment variable.

2026-02-26T13:27:33Z

When "FORCE_COLOR" was set in the environment (such as in django-docker-box) several test cases that rely on string comparisons against exception messages or command line results would fail due to ANSI escape sequences being present in the output. This change resolved the issue by setting the "PYTHON_COLORS" environment variable to "0" for those specific tests, which takes precendence over the presence of "FORCE_COLOR".

Applied Black's 2026 stable style.

Made RemoteTestResultTest.test_pickle_errors_detection() compatible with tblib 3.2+.

2025-10-22T02:10:31Z

tblib 3.2+ makes exception subclasses with __init__() and the default __reduce__() picklable. This broke the test for RemoteTestResult._confirm_picklable(), which expects a specific exception to fail unpickling. https://github.com/ionelmc/python-tblib/blob/master/CHANGELOG.rst#320-2025-10-21 This fix defines ExceptionThatFailsUnpickling.__reduce__() in a way that pickle.dumps(obj) succeeds, but pickle.loads(pickle.dumps(obj)) raises TypeError. Refs #27301. This preserves the intent of the regression test from 52188a5ca6bafea0a66f17baacb315d61c7b99cd without skipping it.

Fixed #36083 -- Ran system checks in ParallelTestSuite workers.

2025-09-17T01:57:22Z

Workers created by ParallelTestSuite were not running system checks in the spawn multiprocessing mode. In general this is fine, but system checks can have side effects expected by tests. This patch runs system checks inside of _init_worker, which is only called by ParallelTestSuite.

Fixed #36531 -- Added forkserver support to parallel test runner.
