Well, it just doesn't... 24 * Partial mock usually means that the complexity has been moved to a different method on the same object. 25 * In most cases, this is not the way you want to design your application. 26 * <p> 27 * However, there are rare cases when partial mocks come handy: 28 * dealing with code you cannot change easily (3rd party interfaces, interim refactoring of legacy code etc.) 29 * However, I wouldn't use partial mocks for new, test-driven & well-designed code. 30 * <p> 31 */ 32 public class CallsRealMethods implements Answer<Object>, Serializable { 33 private static final long serialVersionUID = 9057165148930624087L; 34 35 public Object answer(InvocationOnMock invocation) throws Throwable { 36 return invocation.callRealMethod(); 37 } 38 }
