Unit testing 它'；不可能对Spring数据JPA@Query进行单元测试，真的吗？

首先，目标。什么是单元测试？单元测试是测试最小功能的测试，与测试更多功能的集成测试相反，例如：

• 以任何方式或任何形式生成生产应用程序上下文的测试不是单元测试
• 涉及或甚至意识到应用程序（用@SpringBootApplication标记）类的测试不是单元测试
• 从

  src/main/resources

  加载内容的测试不是单元测试
• 从SpringCloudConfig服务器加载外部配置的测试显然不是单元测试
• 存储库的单元测试不能启动（甚至不知道）web、mvc或安全问题

那么，如何为Spring数据JPA存储库编写单元测试呢？（或者说如此受欢迎和喜爱的框架不支持针对这种事情的纯单元测试？）

我的项目：Spring云（云咨询服务、安全OAuth2服务、eureka、zuul、认证、授权等）

让我们尝试测试最简单的存储库：

public interface StudentRepository extends CrudRepository<Student, Integer> {
    Optional<Student> findByStudentCode(Integer studentCode);
    Optional<Student> findTopByOrderByStudentCodeDesc();

    @Query(value = "SELECT COUNT(*) = 0 FROM t_student WHERE regexp_replace(LOWER(student_name), '\\s', '', 'g') = regexp_replace(LOWER(:suspect), '\\s', '', 'g')", nativeQuery = true)
    boolean isStudentNameSpeciallyUnique(@Param("suspect") String studentName);
}

@DataJpaTest

向上搜索包层次结构并加载生产应用程序：

package org.givespring.atry.university.studentservice;
@EnableResourceServer
@EnableJpaAuditing
@SpringBootApplication(scanBasePackages = "org.givespring.atry.university") // to discover MicroserviceProperties and custom usercontext stuff
public class StudentServiceApp {
    public static void main(String[] args) {
        SpringApplication.run(StudentServiceApp.class, args);
    }
}

因此，错误：

在快捷方式中，单元测试是对小单元的快速测试。什么是单元取决于开发人员或架构指南。它可以是任何小的，可测试的代码段，例如方法或类

另外，如果您仔细想想，就不会有为存储库编写的代码。你依赖于弹簧平台。如果您发现一些bug，请随时提出建议

因此，没有必要为Spring数据JPA存储库方法编写任何单元测试

如果您需要为Spring数据JPA存储库编写单元测试，我想您关心的是方法：save、delete、findOne、findAll等等。在这种情况下，正如您所看到的，这不是很小的，因此需要进行集成测试

此存储库包含一个与spring jpa存储库方法集成测试的示例：
