RSpec Expectations

rspec-expectations adds should and should_not to every object and includes RSpec::Matchers, a library of standard matchers.

Matchers

Matchers are objects used to compose expectations:

result.should eq("this value")

In that example, eq("this value") returns a Matcher object that compares the actual result to the expected "this value".
