# Run one subproject's test suite from that subproject's directory.

# Every subproject here keeps its own pyproject.toml, and its pytest config
# (testpaths, --cov=..., coverage source) is relative to that directory --
# but pre-commit always runs hooks from the monorepo's git root. This wrapper
# supplies the missing `cd`, and fails loudly if the subproject is gone,
# rather than silently testing nothing.
