As a way to assert the path 'foo' is missing, "! test_path_exists foo" is a poor way to do so, as the helper is designed to complain when 'foo' is missing, but the intention of the author who used negated form was to make sure it does not exist. This does not help debugging the tests. Use test_path_is_missing instead, which is a more appropriate helper. Signed-off-by: Junio C Hamano <gitster@pobox.com>
