- Unit tests for `modules` and `module_utils` are now limited to importing only `ansible.module_utils` from the `ansible` module.
- Unit tests other than `modules` and `module_utils` are now run only on Python versions supported by the controller (Python 3.8+).
- Unit tests are now run in separate contexts (`controller`, `modules`, `module_utils`), each using separate invocations of `pytest`.
