rspec-mocks is used to create dynamic "doubles", which stand in for real objects in examples. You can set message expectations on them (i.e. mock methods), and/or stub return values for arbitrary messages:
describe Account do context "when closed" do it "logs an account closed message" do logger = double() account = Account.new account.logger = logger logger.should_receive(:account_closed).with(account) account.close end end end
Message expectations like the one in the example above are verified at the end of each example.
The documentation for rspec-mocks 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.
