Testing HTTP APIs in Ruby
summary
Compares four concrete testing approaches and gives measurable tradeoffs: isolated unit tests with WebMock lead to blind spots, sandboxing against a real server catches protocol drift but turns a 1.5 minute test suite into ~15 minutes and sometimes into 1.5 hours with a partner, and shipping a fast in-memory fake server or a shared rack mapper (using Faraday / rack-client and Sinatra routes) yields quick tests and validated mocks by running both fake and real modes so the fake actually matches the live API.
