Summary
Covers HTTP API testing with Supertest for TypeScript and httpx/pytest for Python. You get practical patterns for REST and GraphQL endpoints, including auth flows, file uploads, request/response validation, and error handling. The examples are solid: shows how to set up fixtures, test protected routes with bearer tokens, validate response timing, and handle common edge cases like 404s and validation errors. The TypeScript side assumes you're using Vitest for your test runner. What's nice is it doesn't overthink things. Just straightforward test patterns you can copy and adapt without wading through theory about testing pyramids or mocking philosophies.
