I'd like to test a service class which has two other service classes like as below using Mockito.
@Service
public class GreetingService {
private final Hello1Service hello1Service;
private final Hello2Service hello2Service;
@Autowired
public GreetingService(Hello1Service hello1Service, Hello2Service hello2Service) {
this.hello1Service = hello1Service;
this.hello2Service = hello2Service;
}
public String greet(int i) {
return hello1Service.hello(i) + " " + hello2Service.hello(i);
}
}
@Service
public class Hello1Service {
public String hello(int i) {
if (i == 0) {
return "Hello1.";
}
return "Hello1 Hello1.";
}
}
@Service
public class Hello2Service {
public String hello(int i) {
if (i == 0) {
return "Hello2.";
}
return "Hello2 Hello2.";
}
}
I know how to mock Hello1Service.class and Hello2Service.class with Mockito like as below.
@RunWith(MockitoJUnitRunner.class)
public class GreetingServiceTest {
@InjectMocks
private GreetingService greetingService;
@Mock
private Hello1Service hello1Service;
@Mock
private Hello2Service hello2Service;
@Test
public void test() {
when(hello1Service.hello(anyInt())).thenReturn("Mock Hello1.");
when(hello2Service.hello(anyInt())).thenReturn("Mock Hello2.");
assertThat(greetingService.greet(0), is("Mock Hello1. Mock Hello2."));
}
}
I'd like to mock Hello1Service.class and inject Hello2Service.class using @Autowired like as below.
I tired to use @SpringBootTest but it did not work.
Is there a better way?
@RunWith(MockitoJUnitRunner.class)
public class GreetingServiceTest {
@InjectMocks
private GreetingService greetingService;
@Mock
private Hello1Service hello1Service;
@Autowired
private Hello2Service hello2Service;
@Test
public void test() {
when(hello1Service.hello(anyInt())).thenReturn("Mock Hello1.");
assertThat(greetingService.greet(0), is("Mock Hello1. Hello2."));
}
}
