/**
* A simple service class that uses the {@link DependencyManager} to get the
* {@link MyService} singleton instance. This is the class that we want to test.
* What's interesting in this example is the static call to the
* DependencyManager. Without byte-code manipulation (provided
* in this example by PowerMock) it would not be possible to return a mock from
* the call to
*
*
* DependencyManager.getInstance();
*
*
* The purpose of this example is to demonastrate how to mock that static
* method.
