Dynamically generates a custom matcher that will match a predicate on your class. RSpec provides a couple of these out of the box:
exist (for state expectations) File.should exist("path/to/file") an_instance_of (for mock argument matchers) mock.should_receive(:message).with(an_instance_of(String))
class Fish def can_swim? true end end describe Fish do predicate_matchers[:swim] = :can_swim? it "should swim" do Fish.new.should swim end end
