How does it handle API authentication?

The skill analyzes and tests common authentication flows, including login procedures, token refresh cycles, and access control for protected routes.

What specifically does the skill validate in responses?

It validates status codes, header configurations, and the structural integrity of the response body to ensure they meet expected requirements.

Can it generate tests from an OpenAPI or Swagger file?

Absolutely. It can parse provided API definitions to ensure your implementation matches the documented contract perfectly.

Can it create tests if I don't have a formal API specification?

Yes, the skill can analyze your source code and route files to infer API structures and generate relevant test cases automatically.

Does this skill support both REST and GraphQL APIs?

Yes, the skill is designed to handle both RESTful endpoints and GraphQL schemas, including queries, mutations, and subscriptions.

Security & Testing

Automates the generation and execution of comprehensive test suites for REST and GraphQL APIs to ensure contract compliance and security.

About

The Automated API Testing Suite empowers Claude to intelligently analyze API definitions—including OpenAPI/Swagger specifications and raw source code—to produce robust testing coverage. It automatically generates test cases for CRUD operations, complex authentication flows, and data integrity checks, while validating response status codes, headers, and body structures. This skill is ideal for developers looking to maintain high-quality API integrations, perform contract testing, and ensure their GraphQL mutations and REST endpoints remain reliable throughout the development lifecycle.

Key Features
