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"
.
