It provides functions like schema(), exact_schema(), and like_schema() that compare actual data against a template defining expected types, nested structures, optional fields, and custom validation rules (regex, enums, lambdas). When data matches the schema, the assertion passes; when it doesn't, a SchemaError is raised with details about the mismatch.\n\nThe package is designed for testing REST endpoints, webhooks, or any code that returns structured data. You define a schema once\u2014a plain Python dict with types and validators\u2014then reuse it across multiple tests. It handles optional fields, nested objects, lists, and custom predicates, making it useful for regression testing API contracts or validating config file parsing without writing repetitive type checks.","worth_installing":"Yes, if you need lightweight schema validation in pytest tests and don't require active maintenance. The package is stable and low-friction to install, but its dormant status (910 days since last release) means it won't receive updates for new pytest or Python versions. Use it for straightforward response validation; consider alternatives if you need ongoing support or complex JSON Schema features."},"id":"pytest-schema","links":{"html":"https://skillfed.io/packages/pytest-schema","md":"https://skillfed.io/packages/pytest-schema.md","pypi":"https://pypi.org/project/pytest-schema/"},"maintenance":{"status":"dormant"},"meta":{"latest_release":"2024-02-16","license_spdx":null,"license_treatment":"permissive","name":"pytest-schema","python_support":"supports_current","summary":"\ud83d\udc4d Validate return values against a schema-like object in testing"},"popularity":{"monthly_downloads":113396,"position":12342,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.1.2"}
