What problem does it solve? Writing comprehensive API tests by hand is slow and error-prone, and most teams only cover happy paths while missing auth failures, boundary values, and adversarial inputs. This Skill scans your API route definitions and generates ready-to-run test suites that systematically cover the error paths where most bugs live. ## Core Features & Use Cases - Route Detection: Scans Next.js App Router, Express, FastAPI, and Django REST Framework codebases to extract every endpoint and HTTP method. - Test Matrix Generation: Produces auth tests (missing/invalid/expired tokens, wrong roles), input validation tests (missing fields, wrong types, boundaries, injection), pagination tests, file upload tests, and rate limiting tests. - Framework-Specific Output: Generates Vitest+Supertest files for Node.js or Pytest+httpx files for Python, with descriptive test names and fixture-based test data. - Use Case: You inherit a legacy Express API with zero test coverage. Run this Skill to scan all routes and generate a baseline test suite covering auth, validation, and error codes for every endpoint before your next release. ## Quick Start Scan my API routes and generate a complete test suite covering authentication, input validation, and error codes for every endpoint.
