With that, our layout has links to all the static pages created in Chapter 3, so that, for example, /about goes to the About page (Figure 5.8).

                    By the way, it’s worth noting that, although we haven’t actually tested for the presence of the links on the layout, our tests will fail if the routes aren’t defined. You can check this by commenting out the routes in Listing 5.21 and running your test suite. For a testing method that actually makes sure the links go to the right places, see Section 5.6.
