API Contract Validator for Assertion Libraries

The `api-contract-validator` package provides a plugin for popular JavaScript assertion libraries like Chai, Should.js, and Jest, enabling validation of API response schemas against OpenAPI (Swagger) definitions. This tool facilitates contract testing by transforming an OpenAPI definition file (YAML or JSON) into a JSON schema, which is then used to validate incoming HTTP responses. The current stable version is 2.2.8, with releases appearing to be maintenance-focused, primarily consisting of dependency upgrades rather than new features or breaking changes. Key differentiators include its plug-and-play integration with existing testing frameworks, support for various HTTP client response formats (axios, superagent, supertest, request, light-my-request), comprehensive assertion failure messages, and the ability to generate coverage reports for API contracts. It supports OpenAPI 3.0 and can handle multiple definition files, making it suitable for larger, modular API landscapes.
