"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

# Add all gems installed in the system to the $LOAD_PATH so they can be used in Rails console with Bundler
if defined?(::Bundler)
  current_ruby_version = `rbenv version`.split(" ").first
  gem_paths = Dir.glob("#{ENV["HOME"]}/.rbenv/versions/#{current_ruby_version}/lib/ruby/gems/**/gems/*/lib")
  gem_paths.each do |path|

# now you can just normally install these gems ('gem install <gem-name>') into your system and keep your Gemfile listing only your app's dependencies. I use this with wirble, awesome_print and looksee and it works just fine. :)
