# https://doc.pytest.org/en/latest/how-to/writing_plugins.html#collection-hooks

# Both our plugin and unittest provide their own collection logic,
# So we can disable the default python collector by giving it empty
# patterns to search for.
# Note that unittest requires that no "Test*" classes exist.
