How to quickly mock services in spring unit tests?

Question

@Bean
public EntityManager(EntityManagerFactory emf) {
   //...
}

How can I quickly mock both of these beans (em + emf) inside a JUnit test? Is there some framework that allows me to define eg @Mock EntitiyManager em; ?

Answer 1

Take a look at springockito together with spring-test . It integrates spring with mockito and supports both annotation based mocks and mocks configured in a spring applicationContext.

Answer 2

You seem to be aware of the @Mock annotation, so presumably you know what Mockito is. You just mock the EntityManager exactly the same way you would mock anything else.

@Mock EntitiyManager em;
initMocks();
MyService myService = new MyServiceImpl(em);
