brouberol and I worked through and improved the pytest CI job from 8-9 minutes to under 2 minutes. On my work laptop, make test now finishes in under 30 seconds.
Action required: rebase any in-progress patches that add DagProperties DagProperties no longer infers the DAG file from the call stack. You must pass it explicitly: props = DagProperties( _dag_file=__file__, ... ) Every DAG in main has already been updated. If your branch adds a DagProperties without either _dag_file or _variable_name, DAG parsing now fails with an AssertionError. This can be easy to miss: your branch's CI may pass, but the merge result can fail because CI tests your branch, not the rebased merge. Rebase onto main before merging.
Action required: rebuild your dev image once pytest-xdist is now a dependency. Because the development image is rebuilt only when Dockerfile.dev changes, you'll need to rebuild it manually once: make test.image.rm && make test Otherwise, pytest will fail with: unrecognized arguments: -n Other test changes make test now runs with 4 workers by default. Use make test jobs=1 for a small subset of tests.
