| Calls to `Mockito.when` should always be accompanied by a call to a method like |
| `thenReturn`. |
| |
| ```java |
| when(mock.get()).thenReturn(answer); // correct |
| when(mock.get()) // oops! |
| ``` |
| |
| Similarly, calls to `Mockito.verify` should call the verified method *outside* |
| the call to `verify`. |
| |
| ```java |
| verify(mock).execute(); // correct |
| verify(mock.execute()); // oops! |
| ``` |
| |
