For convenience, the code in Listing 9.5 uses a helper to sign in a user inside the tests. The method is to visit the signin page and submit valid information, as shown in Listing 9.6

This is necessary when using one of the HTTP request methods directly (get, post, put, or Delete), as we’ll see in Listing 9.47. (Note that the test cookies object isn’t a perfect simulation of the real cookies object; in particular, the cookies.permanent method seen in Listing 8.19 doesn’t work inside tests.)
