2025-07-23tests/thread: Allow thread tests to pass with the native emitter.Damien George
The native emitter will not release/bounce the GIL when running code, so if it runs tight loops then no other threads get a chance to run (if the GIL is enabled). So for the thread tests, explicitly include a call to `time.sleep(0)` (or equivalent) to bounce the GIL and give other threads a chance to run. For some tests (eg `thread_coop.py`) the whole point of the test is to test that the GIL is correctly bounced. So for those cases force the use of the bytecode emitter for the busy functions.

2020-03-30tests: Format all Python code with black, except tests in basics subdir.David Lechner
This adds the Python files in the tests/ directory to be formatted with ./tools/codeformat.py. The basics/ subdirectory is excluded for now so we aren't changing too much at once. In a few places `# fmt: off`/`# fmt: on` was used where the code had special formatting for readability or where the test was actually testing the specific formatting.
2016-06-28tests/thread: Remove need to sleep to wait for completion in some tests.Damien George
Use a lock and a counter instead, and busy wait for all threads to complete. This makes test run faster and they no longer rely on the time module.
