Adding a Page

Having seen test-driven development in action in a simple example, we’ll use the same technique to accomplish the slightly more complicated task of adding a new page, namely, the About page that we intentionally left off in Section 3.1.2. By writing a test and running RSpec at each step, we’ll see how TDD can guide us through the development of our application code.

We’ll get to the Red part of the Red-Green cycle by writing a failing test for the About page. Following the models from Listing 3.11, you can probably guess the right test (Listing 3.13).
