To test the additional pause class, all you need to do in the test class is add another
button instance. With three buttons, a little more positioning thought has to go into
it, but expanding the State design pattern is very easy. All the changes for adding the
additional button are on lines 45-48 and 53. So just edit the TestVid.as file as shown
in Example 10-19, and save it as TestPause.as.
