EasyMock Mocking Framework
EasyMock allows a test to create a mocked object directly from an interface, without having to define a class and mock every method defined by the API. The test writer can define only the methods that are required to execute the test. In this example, a mock is created for the HostService API which is passed in to the HostToHostIntentCompiler class.
