test_hook_register_actions_no_duplicates has its assertion inside the with pytest.raises(StartupError) block, below the call that raises:

with pytest.raises(StartupError) as ex:
    await ds.invoke_startup()
    assert f"Duplicate action {duplicate}" in str(ex.value)

invoke_startup() raises, so the assertion is never reached and the error message is unchecked. (ex.value is also only populated after the block exits.)

Verified by replacing the expected string with a deliberately wrong one:

assertion	position	result
wrong	inside the block (as-is)	2 passed
wrong	below the block	2 failed
correct	below the block	2 passed

So the message does match once the assertion runs. tests/test_plugins.py is 161 passed, 4 skipped before and after, and black --check is clean.
