The corresponding application code simply involves adding index to the list of actions protected by the signed_in_user before filter, as shown in Listing 9.22.

The next set of tests makes surethat, for signed-in users, theindex page has theright title/heading and lists all of the site’s users. The method is to make three factory users (signing in as the first one) and then verify that the index page has a list element (li) tag for the name of each one. Note that we’ve taken care to give the users different names so that each element in the list of users has a unique entry, as shown in Listing 9.23.
