spring - 无法连接到运行 Junit 测试的 Redis

Question

我有一个基本的 SpringBoot 2.0.4.RELEASE 应用程序。使用 Spring Initializer、JPA、嵌入式 Tomcat、Thymeleaf 模板引擎，并将其打包为可执行 JAR 文件，我根本不使用任何 Redis 配置

我创建了这个 Junit 测试:

@ContextConfiguration(classes={TestSystemConfig.class})
@RunWith(SpringRunner.class)
@SpringBootTest(classes = AzureApplication.class) 
public class RoleServiceTests {

    @Autowired
    protected  RoleService  roleService;


    @Test
    public void testSaveAndFindByName() throws Exception {

        roleService.save(new Role(RolesEnum.ADMIN));
        assertNotNull (roleService.findByName(RolesEnum.ADMIN.getRoleName()));

    }
}

但是当我运行测试时我得到了这个异常:

org.springframework.data.redis.RedisConnectionFailureException: Unable to connect to Redis; nested exception is io.lettuce.core.RedisConnectionException: Unable to connect to localhost:6379

    at com.sun.proxy.$Proxy131.getByName(Unknown Source)

但是像这样的其他 Junit 测试运行良好:

@ContextConfiguration(classes={TestSystemConfig.class})
@RunWith(SpringRunner.class)
@SpringBootTest(classes = AzureCloudApplication.class) 
public class CompanyServiceTests {

    @Autowired
    protected  CompanyService  companyService;


    @Test
    public void testFindAll() throws Exception {

        Iterable<Company> companies = companyService.findAll();
        assertTrue (((Collection<?>) companies).size() > 0);            
    }


    @Test
    public void testCompanyUsers() throws Exception {

        Iterable<Company> companies = companyService.findAll();
        Company company = companies.iterator().next();

        assertNotNull (company);

        company = companyService.companyUsers(company.getId());
        assertTrue (((Collection<?>) company.getUsers()).size() > 0);           
    }

}

在被质疑的测试中使用了与redis相关的服务。 因此，您需要模拟 redis。 您可以查看有用的博客文章 mentinoned here关于这种情况。 或者 this关于计算器的问题。
