All other bean wiring seems ok as the Spring boot application can start (when I comment out the test class). This is the root cause, And then, we change the code like this: @RunWith(SpringRunner. We call it ‘code under test‘ or ‘system under test‘. 使用@InjectMocks注解将被测试的对象自动注入到测试类中，使用@Mock注解创建模拟对象。 在testGetUserById方法中，我们首先使用when方法配置userRepository模拟对象的行为. but spring does not know anything about that object and won't use it in this. While testing them, i would like to have only 2 of the classes (B & C) as mocks and have class D to be Autowired as normal running, this code is not working for me: @RunWith(MockitoJUnitRunner.
