Mocking the Qualified beans using mockito for a spring-boot application

Question

consider my scenario

public class SomeClass {
  @Autowired @Qualifier("converter1") private IConverter converter1;
  @Autowired @Qualifier("converter2") private IConverter converter2;

  public void doSomeAction(String mimeType) {
    converter1.execute();
    converter2.execute();
  }
}

This is my code.

In order to test this

@RunWith(MockitoJUnitRunner.class)
public class SomeClassTest {
  @Mock(name="converter1") IConverter converter1;
  @Mock(name="converter2") IConverter converter2;
  @InjectMocks SomeClass class = new SomeClass();
  @Test
  public void testGetListOfExcelConverters() throws Exception {
    class.doSomeAction("abcd");
  }
}

Here the mocks are not getting injected, please help with the proper mechanism for mocking a qualified beans.

If this is not the right way to code using spring, please let me know the correct method for using this.

Answer 1

You can mock beans using a test configuration:

@Configuration
public class TestConfig {
   @Bean
   public MyService myService() {
      return Mockito.mock( MyService.class );
   }
}

Answer 2

I've found this solution:

@RunWith(MockitoJUnitRunner.class)
public class SomeClassTest {

  @Mock()
  @Qualifier("converter1")
  IConverter converter1;

  @Mock() 
  @Qualifier("converter1")
  IConverter converter2;

  @InjectMocks SomeClassTest testObj = new SomeClassTest();

  @Test
  public void testGetListOfExcelConverters() throws Exception {
    testObj.doSomeAction("abcd");
    verify(converter1).execute();
    verify(converter2).execute();
  }
}

BTW, I haven't found this in doc.

Answer 3

For me, both existing answers were insufficient.

@riddy 's answer did not take into account different test cases.

@jhericks ' answer did not use the Spring context, which caused other issues down the line.

Here's my solution:

@MockBean
@Qualifier("myNamedBean")
private SomeBean someBean;

As simple as that.
