pytest-jev

pytest plugin for semantic assertions about LLM output: jev.expect batches Noul claims about one text, reports each probability, and by default fails uncertain claims (holds needs at least 0.8, lacks at most 0.2); Choice checks the selected option and Score checks probability mass across ordered levels. It caches answers in .pytest_cache, skips Jev tests without a key by default, and sends tested text and context to TypeSafe or OpenRouter.
