How does it handle API authentication?

It follows security best practices by using helper-based token management rather than hardcoded fixtures or credentials.

Which API frameworks does this skill support?

It supports a wide range of popular tools including Postman/Newman, REST Assured, SuperTest, and httpx for various programming environments.

Does it support contract testing?

Yes, it provides specific workflows for Pact to facilitate consumer-driven contract testing between microservices.

Can it help with GraphQL APIs?

Yes, the skill includes specialized guidance for GraphQL-specific testing scenarios and schema validation patterns.

Can I use it to mock external dependencies?

Absolutely. It includes configurations for WireMock and MSW to intercept network requests and stub external service behavior.

Seguridad y Pruebas

Automates comprehensive API testing, contract validation, and mock server configuration for REST and GraphQL services.

This skill empowers Claude to design and implement robust API testing infrastructures using industry-standard tools like SuperTest, REST Assured, and Newman. It covers the full lifecycle of API quality assurance, from writing integration tests and validating OpenAPI schemas to setting up Pact for consumer-driven contract testing and WireMock for dependency stubbing. Whether you are auditing endpoint coverage against HTTP status code checklists or establishing performance baselines for CI/CD pipelines, this skill ensures your backend services remain reliable, secure, and performant.
