Inject Out Of

[jameskennard]

Mockito-Collections is primarily aimed at injecting Collections of Mocks into an Object that is under test. We could potentially consider reversing this as well, for example given the annotation InjectOutOf:

@InjectMocks
private MyDelegate delegate;

@InjectOutOf
private Collection<MyListener> listeners;

@Test
public void shouldAdd() {
    // Given
    MyListener listener = mock(MyListener.class);

    // When
    delegate.add(listener);

    // Then
    // assertTrue(listeners.contains(listener));
}
