springboot 测试

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
</dependency>

@RunWith(SpringRunner.class) //底层用junit  SpringJUnit4ClassRunner
@SpringBootTest(classes = Boot1testApplication.class) //启动整个springboot工程

 @Test
 public void fangfa1()
    {
       // stringRedisTemplate.opsForValue().set("key1","value1");
        String key1 = stringRedisTemplate.opsForValue().get("key1");
        System.out.println(key1);
    }

常见错误

JUnit测试提示Java.lang.Exception: No runnable methods

原因：没有在方法上指定@Test和@Test的包导错了

@Test导入的包错了，spring-test需要的Junit是org.junit.Test
