You could test your app using something like Cucumber only and I believe that's a good start but consider the following: You have an authentication system that protects the administration of some resource. You would have Cucumber scenarios that check your login form, that administrators can see and edit the resource and that non-administrators can't see the edit buttons or load the edit resource page In order to improve security, you should ensure that people can't issue the POST and PUT requests directly (which completely by-passes the browser and therefore is not testable by Cucumber (in it's traditional usage) Enter controller tests that can issue specific calls against the create and update methods covering all sad paths that are achievable directly against the controller ensuring there is no way to change the resource if you are not an admin. It doesn't stop there, your entire application relies on some methods on your model such as authenticate and admin? etc. Unit tests are your friend here because you can write specific tests to ensure that authenticate works correctly and that no-one can inject their admin status.
