potiuk opened a new pull request, #30450: URL: https://github.com/apache/airflow/pull/30450
One of the steps in our CI is to collect tests, which is to prevent parallel tests from even starting when we know test collection will fail (it is terrible waste of resources to start 20 test jobs and initialize databases etc. when we know it is not needed. This however introduced a single point of delay in the CI process, which with the recent collection protection implemented in #30315 piled up to more than 5 minutes occassionally on the CI machines of ours, especially on public runners. This PR utilises our existing test framework to be able to parallelise test collection (Pytest does not have paralllel collection mechanism) - also for localised PRs it will only run test collection for the test types that are going to be executed, which will speed it up quite a lot. This might get further sped up if we split Provider tests into smaller groups to parallelise them even more. <!-- Thank you for contributing!
