测试容器初始化后存储库始终为 null

Question

我正在尝试使用 TestingContainers。我能够达到运行但我的测试始终为空。我试图避免嘲笑，而是拥有真实数据。

存储库

@Sql("classpath:data.sql")
class OrderDataRepositoryTest extends AbstractTestConfiguration {

    //@Mock
    @MockBean
    //@Autowired
    private OrderDataRepository orderRepository;

    private AutoCloseable closeable;

    @BeforeEach
    public void init() {
        closeable = MockitoAnnotations.openMocks(this);
    }

    @AfterEach
    void closeService() throws Exception {
        closeable.close();
    }

    @Test
    void getAllUsersTest() {
        List<Order> orders = orderRepository.findAll();
        orders.toString();
    }

}

配置

@AutoConfigureTestDatabase(replace = AutoConfigureTestDatabase.Replace.NONE)
@Testcontainers
public abstract class AbstractTestConfiguration {

    @Container
    private MySQLContainer database = new MySQLContainer("mysql:8.0");


    @Test
    public void test() {
        assertTrue(database.isRunning());
    }


}

主要

@SpringBootTest
@Sql("classpath:init.sql")
@TestPropertySource("classpath:application-test.yml")
class TentingContainerApplicationTests {

}

application.properties

spring:
  application:
  datasource:
      url: jdbc:mysql:8.0:///test?TC_INITSCRIPT=file:src/main/resources/init.sql
      driver-class-name: com.mysql.jdbc.Driver

注释掉了

//@Mock
@MockBean
//@Autowired

是我试过的。模拟当然可行，但我想要@services 和@repository 类.

的真实数据

建议？

如果您想单独测试与数据库相关的代码（我假设您使用的是 Spring Data JPA），那么 @DataJpaTest 非常适合。

此注释将创建一个 sliced Spring context for you that contains only persistence relevant beans，例如：DataSource、EntityManager、YourRepository。这不包括您的服务类、您的 @Component 类或 @RestController.

默认情况下，此注释尝试将嵌入式内存数据库配置为 DataSource。我们可以覆盖这个（你已经用你的一些代码示例做了）行为来使用 Testcontainers:

@DataJpaTest
@Testcontainers
@AutoConfigureTestDatabase(replace = AutoConfigureTestDatabase.Replace.NONE)
class OrderDataRepositoryTest {
 
  @Container
  static MySQLContainer database = new MySQLContainer("mysql:8.0");
 
  @DynamicPropertySource
  static void setDatasourceProperties(DynamicPropertyRegistry propertyRegistry) {
    propertyRegistry.add("spring.datasource.url", database::getJdbcUrl);
    propertyRegistry.add("spring.datasource.password", database::getPassword);
    propertyRegistry.add("spring.datasource.username", database::getUsername);
  }
 
  @Autowired
  private OrderDataRepository orderRepository;
 
  @Test
  void shouldReturnOrders() {

  }
}

如果您想编写另一个包含所有 bean 并启动嵌入式 servlet 容器的测试，请使用 look at @SpringBootTest for writing integration tests。

@SpringBootTest(webEnvironment = WebEnvironment.RANDOM_PORT)
@Testcontainers

class MyIntegrationTest {
 
  @Container
  static MySQLContainer database = new MySQLContainer("mysql:8.0");
 
  @DynamicPropertySource
  static void setDatasourceProperties(DynamicPropertyRegistry propertyRegistry) {
    propertyRegistry.add("spring.datasource.url", database::getJdbcUrl);
    propertyRegistry.add("spring.datasource.password", database::getPassword);
    propertyRegistry.add("spring.datasource.username", database::getUsername);
  }

@Autowired
private ServiceA serviceA;

@Autowired
private OrderDataRepository orderDataRepository;

}

在为测试和 Mockito 使用 Spring TestContext 时，请务必理解 difference between @Mock and @MockBean。
