Symmetric API Testing
summary
Claims a concrete pattern: record live HTTP requests and responses, replay them in tests, and auto-generate native types so client and server share the exact contract. Uses Go examples—anaconda client, a tee reader to record responses, go-json to infer structs and go generate to refresh code. Demonstrates a real failure mode (Twitter changed a string into an array) and shows the recorder/replayer approach reduces test fragility, shortens build loops, and keeps client and server compatible.
