[rspec-users] Mocking: brittle specs and tight coupling?

Another tip: To TDD a new feature, don't clone a high-level test which calls 
code which calls code which calls the code you need to change.

Start by cloning the lowest level test possible. If there is none, write one. 
And if the test still wouldn't be low level enough, start by refactoring the 
line you need to change, to pull it out into a method you can test directly.
