Comments on: How simple is too simple? http://dannorth.net/2006/05/how-simple-is-too-simple It's all behaviour Sat, 11 Oct 2008 19:09:08 +0000 http://wordpress.org/?v=2.6.2 By: Dan North http://dannorth.net/2006/05/how-simple-is-too-simple#comment-27 Dan North Sun, 04 Jun 2006 21:06:03 +0000 http://dannorth.net/archives/22#comment-27 That's an interesting observation. Before I got into mocking using jmock, I was also very wary of interfaces everywhere. Especially the dreaded Impl antipattern - the 1-1 mapping of CheeseService to CheeseServiceImpl. I've found that using TDD with mocks helps me "discover" services and dependencies that I mock using interfaces, so that I can defer worrying about the implementations until later. Tim Mackinnon - one of the originators of mock objects - describes these interfaces as "flex points". The interfaces that come out of mock-based TDD seem to appear just where I need multiple implementations down the line. Still not sure how, but I trust the mocking pixies and it seems to work.
