Developer tests - big theory ,[object Object]

EasyMock mock types (1) ,[object Object],@ Before public void setUp() { userDao = EasyMock. createMock (UserDao. class ); validator = new UserValidator( userDao ); } @ Test public void duplicateLoginNameIsInvalid() throws Exception { User user = ... errors = new BindException(user, "User" ); EasyMock.expect( userDao .isValidLoginName(user)).andReturn( false ); EasyMock.replay( userDao ); validator .validate(user, errors); assertTrue(errors.toString(), errors.hasErrors()); EasyMock.verify( userDao ); }

EasyMock mock types (2) ,[object Object]

useful if test contains many different or complex scenarios (bad style?) userDao = EasyMock. createStrictMock (UserDao. class );

EasyMock mock types (3) ,[object Object]

Warning: are you in “getting it pass” mode?

if cannot implement nice equals for some argument (but there is better alternative!) filterDao = createNiceMock(FilterDao. class ); //expect(filterDao.getFilterId("unique-filter-name", USER_ID)).andReturn(null); replay( filterDao ); validator.validate(filter, errors); assertFalse(errors.hasErrors()); verify( filterDao );
