我需要使用模拟 dao 来测试服务方法。而且我还需要测试 dao 方法以了解某个方法是否正常工作。但是我无法将 mockito 与 spring boot 集成。如果我使用MockitoJUnitRunner第一个测试作品，如果我使用SpringJUnit4ClassRunner第二个测试作品。我也尝试使用@MockBean而不是@Mock，但它也不起作用。
//SpringJUnit4ClassRunner
//MockitoJUnitRunner
@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest
public class BookServiceTests {
@Mock
private BookDao bookDao;
@Autowired
private BookDao bookDao2;
private List<Book> listOfBooks;
@InjectMocks
@Autowired
private BookService bookService;
@PersistenceContext
private EntityManager entityManager;
@Before
public void setup() {
MockitoAnnotations.initMocks(this);
}
@Test
public void testGetMostPopularBooksInService() {
fillListOfBooks();
when(bookDao.selectMostPopularBooks(3, 3)).thenReturn(listOfBooks);
assertEquals(3, bookService.getMostPopularBooks(0, 3).size());
}
@Test
@Transactional
public void testSelectMostPopularBooks() {
fillDBByBooks();
List<Book> listOfPopularBooks = bookDao2.selectMostPopularBooks(0, 3);
assertEquals(3, listOfPopularBooks.size());
assertEquals("Марсианинн", listOfPopularBooks.get(0).getName());
}
private void fillListOfBooks() {
Writer writer = new Writer(3, "Джек", "Лондон", "...", null);
listOfBooks = new ArrayList<>();
listOfBooks.add(new Book(6, "Зов предков", 1990, writer, "...",
10, new HashSet<>(Arrays.asList(new Genre(1, "Психология")))));
listOfBooks.add(new Book(8, "Зов предков", 1990, writer, "...",
25, new HashSet<>(Arrays.asList(new Genre(1, "Психология")))));
listOfBooks.add(new Book(10, "Зов предков", 1990, writer, "...",
35, new HashSet<>(Arrays.asList(new Genre(1, "Психология")))));
}
private void fillDBByBooks() {
Writer writer = new Writer(28, null, null, null, null);
entityManager.persist(new Book(0, "Огонь и вода", 1990, writer, "...",
105, new HashSet<>(Arrays.asList(new Genre(1, "Психология")))));
entityManager.persist(new Book(0, "Солнце", 1990, writer, "...",
150, new HashSet<>(Arrays.asList(new Genre(1, "Психология")))));
entityManager.persist(new Book(0, "Космос", 1990, writer, "...",
200, new HashSet<>(Arrays.asList(new Genre(1, "Психология")))));
entityManager.persist(new Book(0, "Марсианин", 1990, writer, "...",
225, new HashSet<>(Arrays.asList(new Genre(1, "Психология")))));
}
}
首先，测试类中缺少您的上下文配置注释，因此您不会在那里获得任何 spring 容器支持或自动装配。它应该是这样的：
@RunWith(SpringRunner.class)
@SpringBootTest
@ContextConfiguration(
classes = {MyApplicationConfig.class}
)
public class MyTestClass
其次，我不会在同一个测试类中混合模拟 bean 和自动装配的 bean。我不确定这是否可能。我建议您将测试分为两类。一个具有真实的 DAO 和可用的上下文配置，另一个类只有纯模拟。
