object-mother-pattern

Use this skill whenever a user is writing Python tests, pytest fixtures, validation tests, factories, or generated test data with the object-mother-pattern package. It teaches agents how to choose and call Object Mother classes, compose ListMother and DictMother, create custom BaseMother subclasses, update exports and docs, and avoid brittle random assertions. Trigger when prompts mention object mothers, object_mother_pattern, Object Mother Pattern, test data, invalid values, boundary values, UUIDs, dates, URLs, identifiers, credit cards, or package mother APIs.
