title: RoR Tutorial - A direct test the full_title helper
body: <p>I am working on the RoR Tutorial chapter 5 exercises and I can't seem to figure out what text to use in place of the "FILL_IN" I've tried reading the error messages by trying to match the actual with the expected. What am I doing wrong? Also, can someone explain how the <code>&lt;expected&gt;</code> and <code>&lt;actual&gt;</code> work in this test since I don't see the words "expected" or "actual" anywhere.</p>
