This test should be simple if you've already read chapter 7. We start by defining the
Mockery context B and the object that we want to mock C . After that, in the @Before
method we initialize the request object to be ready for usage D . The next step defines
several test methods, each of which will test the showAlbumDetails method by specify-
ing a different parameter in the request. For each of those methods we define the
expectations E , initialize AlbumDetailsBean F , set the mock request to the bean G ,
and execute the method under test H . The final test is to perform the assertions that
we want I .
