End-to-End Testing

Outside-in testing

We’ll follow a testing practice called outside-in testing, which involves writing an end-to-end test that defines the feature (the “outside”) and augmenting it with a series of unit tests that drive the actual code and design (the “inside”).

Capybara

Capybara will make our end-to-end tests easier to read and write. It allows tests to describe user interaction with the web page and the document object model (DOM). We’ll cover Capybara and end-to-end testing in more detail in the chapter “Integration Testing with Capybara and Cucumber”.
