Gary Bernhardt's RubyConf 2012 talk on testing in isolation without mocking everything. It goes through behavior versus data, mutation versus immutability, and how a functional core with an imperative shell yields natural isolation and parallelism.
HN 推薦的原因： HN recommends it as the canonical presentation of 'functional core, imperative shell' and a practical answer to unit versus integration testing.
