rspec-expectations is used to set expectations in executable examples:
describe Account do it "has a balance of zero when first created" do Account.new.balance.should eq(Money.new(0)) end end
The documentation for rspec-expectations is a work in progress. We'll be adding Cucumber features over time, and clarifying existing ones. If you have specific features you'd like to see added, find the existing documentation incomplete or confusing, or, better yet, wish to write a missing Cucumber feature yourself, please submit an issue or a pull request.
