junit 测试中的 JPA 存储库为空

Question

我正在尝试为我的存储库/服务类编写一个非常基本的测试，但由于我似乎无法弄清楚的原因，我的自动装配存储库始终为空。

这是回购类

public interface RuleRepository extends JpaRepository<Rule, UUID> {   

    public Optional<Rule> findByName(String name);

}

和测试

@DataJpaTest

@ContextConfiguration(classes = MyApplication.class)

public class RulesTest {

    @Autowired

    private RuleRepository ruleRepository;  

    @Test

    public void testSaveOneRule() {

        if (ruleRepository == null) {

            System.err.println("HERE");

            assertTrue(true);

        } else {

              assertTrue(false);

          }

    }

}

有没有人有任何想法？考试总是通过...

编辑：我不确定这是否是一个值得发布新帖子的错误，但使用注释运行会@RunWith(SpringRunner.class)产生错误RulesTest.testSaveOneRule ? IllegalState Failed to load ApplicationContext...

MyApplication.class 的内容

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication

public class MyApplication {

    public static void main(String[] args) {

        SpringApplication.run(MyApplication.class, args);

    }

}

Answer 1

对于测试存储库，您应该具有注释：@DataJpaTest&nbsp;@RunWith(SpringRunner.class)&nbsp;@SpringBootTest(classes=MyApplication.class)

Answer 2

我注意到您缺少此注释 @RunWith(SpringRunner.class)我一直在关注这个页面，我可以做到https://grokonez.com/testing/datajptest-with-spring-boot

Answer 3

如果您使用 JPA，请添加类 Test @DataJpaTest。前任。：@DataJpaTestpublic class CategoriaServiceTest {&nbsp; &nbsp;&nbsp;&nbsp; &nbsp; @Autowired&nbsp; &nbsp; private CategoriaRepository repository;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp; @Test&nbsp; &nbsp; public void test() {&nbsp; &nbsp; &nbsp; &nbsp;&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; Categoria categoria = new Categoria(null, "Teste");&nbsp; &nbsp; &nbsp; &nbsp;&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; Categoria categoriaSaved = repository.save(categoria);&nbsp; &nbsp; &nbsp; &nbsp;&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; assertEquals(categoria.getNome(), "Jefferson");&nbsp; &nbsp; }}
