Can it generate tests from Swagger or OpenAPI files?

Yes, it automatically searches for and analyzes OpenAPI/Swagger specifications to discover endpoints, request/response schemas, and authentication requirements.

What types of test cases are generated by default?

The skill generates tests for happy paths, input validation, authentication (401/403), resource not found (404), and response schema validation.

Which frameworks does the API Test Generator support?

It supports popular native frameworks including pytest (Python), vitest/jest (JavaScript/TypeScript), JUnit 5 (Java/Kotlin), and go test (Go).

Does this skill require external tools like Postman?

No, this skill generates tests as native code using standard libraries like httpx, supertest, or REST-assured, eliminating the need for intermediate tools or external platforms.

Security & Testing

Generates production-ready API test suites using native unit test frameworks directly within your existing codebase.

The API Test Generator skill automates the creation of comprehensive API test suites by analyzing your project's source code or OpenAPI specifications. Unlike traditional tools that rely on intermediate platforms like Postman or Karate, it generates native, first-class code for frameworks such as pytest, vitest, JUnit, and Go's testing package. It systematically builds test cases covering happy paths, edge cases, authentication flows, and schema validations, ensuring high-quality integration testing that lives directly alongside your application code.
