61 pytest tests generated from Swagger Petstore

Generated from your public OpenAPI spec. They cover the happy path, missing auth, missing required params, wrong types and response-schema checks for each endpoint. Plus 3 multi-step flows that create a resource and pass its id through read, update and delete. Generated, not run against your API — point API_BASE_URL at a test environment and run pytest.
