http://avdi.org/devblog/2008/10/28/complex-hash-expectations-in-rspec/Complex Hash Expectations in RSpec Tuesday, October 28, 2008 When spec-ing something that calls method which takes a set of nested hashes (as many Rails methods do), it may be tempting to use #hash_including to test for only the values you care about. However #hash_including won’t work the way we might hope for nested hashes. …
