	# Tests are split into multiple jobs to accelerate the CI.
	# Different jobs should be organized to take approximately the same
	# time to complete (and not be prohibitely slow).
	# Because GitHub Actions don't support YAML anchors, we have to place the
	# splitting of testfiles into groups in the strategy/matrix/test-subset
	# and can't re-use the groups across jobs.
	# A pre-commit hook (scripts/check_all_tests_are_covered.py)
	# enforces that test run just once per OS / floatX setting.
