Mockito: Inject real objects into private @Autowired fields

Question

I\'m using Mockito\'s @Mock and @InjectMocks annotations to inject dependencies into private fields which are annotated with Spring\'s @Autow

Answer 1

In Spring there is a dedicated utility called ReflectionTestUtils for this purpose. Take the specific instance and inject into the the field.

@Spy
..
@Mock
..

@InjectMock
Foo foo;

@BeforeEach
void _before(){
   ReflectionTestUtils.setField(foo,"bar", new BarImpl());// `bar` is private field
}
