如何在Spring Roo中使用JUnit测试？(EntityManager的问题)

<dependency>
    <groupId>junit</groupId>
    <artifactId>junit</artifactId>
    <version>4.12</version>
    <scope>test</scope>
</dependency>

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = MyProjectApplication.class)
@WebAppConfiguration
@RooIntegrationTest(entity = YourEntity.class)
public class YourEntityIntegrationTest {

    @Autowired
    private YourEntityDataOnDemand dod;

    @Test
    public void testSomeMethod() {
        // 在这里编写你的测试逻辑
    }
}

@Test
public void testSomeMethod() {
    YourEntity entity = new YourEntity();
    // 设置实体属性
    entity.setName("Test");
    // 使用EntityManager保存实体对象到数据库
    entityManager.persist(entity);
    // 断言实体对象是否成功保存到数据库
    assertNotNull(entity.getId());
}
