Integration Testing with Capybara

Integration testing is awesome. Years ago, running integration tests was painful, slow, and they were so brittle that every change to the codebase broke the test suite.

Today it's a different story. We have amazing tools that make a tough job much easier. Let's check them out.

Background on Integration Testing

Integration tests are critically important because they exercise your application just like a real user. They therefore depend on the full stack from your models up through your controllers, helpers, view templates, web server, database, and middleware.
