MiniTest: Write Awesome Tests
summary
Argues that MiniTest cuts testing overhead by being tiny and readable and ships with Ruby 1.9 as a drop‑in for test/unit, so no big install. Demonstrates unit, spec and mock styles, a Sinatra/Rack example with a ~100–200 line spec shim and random test ordering with seed to surface order dependencies. Shows a fetcher test that replaces real HTTP with a local stub and serialize URL cache to disk so tests run fast and offline.
