java - Spring Data Jpa 保存测试失败

Question

我真的没有选择。我正在尝试将实体保存到数据库并断言该值已被持久化。我正在使用 H2 内存数据库。

我不知道我做错了什么。每次运行应用程序时，我都会得到一个空值。

这是我的类(class):

汽车存储库测试

@RunWith(SpringRunner.class)
@DataJpaTest(showSql= true)
public class CarRepositoryTest
{
    @MockBean
    private CarRepository repo;

    @Test
    public  void saveTest() throws Exception {

        Car car = new Car(1L, "MyFirstCar");
        Car saved =  repo.save(car);

        assertNotNull(saved);
    }
}

汽车存储库

@Repository
public interface CarRepository extends CrudRepository<Car, Long>
{
}

application.properties

spring.datasource.url=jdbc:h2:mem:testdb;DB_CLOSE_DELAY=-1
spring.h2.console.enabled=true
spring.h2.console.path=/h2console
spring.datasource.username=sa
spring.datasource.password=
spring.datasource.driverClassName=org.h2.Driver
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.H2Dialect
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=create-drop

JpaTestApplication

@SpringBootApplication
@Configuration
@EnableJpaRepositories(basePackages="com.al.repository")
public class JpaTestApplication {

    public static void main(String[] args) {
        SpringApplication.run(JpaTestApplication.class, args);
    }
}

Answer 1

答案就像 Autowiring 存储库一样简单，而不是像 @SeanCarrol 建议的 MockBean

所以我的测试现在看起来像这样:

@RunWith(SpringRunner.class)
@DataJpaTest(showSql= true)
public class CarRepositoryTest
{
    @Autowire
    private CarRepository repo;

    @Test
    public  void saveTest() throws Exception {

        Car car = new Car(1L, "MyFirstCar");
        Car saved =  repo.save(car);

        assertNotNull(saved);
    }
}
