"Why You Don't Get Mock Objects" by Gregory Moeck

RubyConf 2011 | 2011-09-29 | Gregory Moeck (@gregmoeck) | Slides

• Recommended as the best book on mocks: Growing Object-Oriented Software, Guided by Tests by Steve Freeman & Nat Pryce
• Common arguments against mocks
  • They duplicate implementation
  • They lead to brittle tests
• Mock objects + procedural programming = bad idea
• If you're doing traditional Rails development (which tends to follow more of a "procedural", do-this-and-then-do-that style), mock objects probably aren't for you
