# Standalone regression test for tasks.py helpers -- run directly with
# `pytest shared/stinkytofu/tests/test_tasks.py`. Not wired into CTest: the
# python_module/tests/ glob in tests/CMakeLists.txt is scoped to tests that
# import the compiled stinkytofu module; this one only exercises tasks.py
# itself and needs no build.
