Example of using Mockito with Junit Parameterized tests

BradsParameterizedMockTest

@RunWith(Parameterized.class)
public class BradsParameterizedMockTest {

	private UserManager userManager = new UserManagerImpl();
	
    @Mock private UserService userService;
    
    private String userName = null;
    private User expectedUser = null;
	
	public BradsParameterizedMockTest(String userName, User user) {
		this.userName = userName;

	}
	
	@Parameters
	public static List<Object[]> balanceRates() {

	}
	
	@Before
	public void setUp() {
		initMocks(this);
		userManager.setUserService(userService);
	}
	
	@Test
	public void shouldReturnExpectedUser() {		
		// given
		when(userService.findUserByName(userName)).thenReturn(expectedUser);
		
		// when
		User user = userManager.findUser(userName);
		
		// then
		assertThat(user, is(equalTo(expectedUser)));
		verify(userService).findUserByName(userName);
		verifyNoMoreInteractions(userService);
	}
}

Very useful! I could move forward quickly with this example.
