springboot中@Test引入的依赖

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

一旦依赖了spring-boot-starter-test，下面这些类库将被一同依赖进去：

JUnit：java测试事实上的标准，默认依赖版本是4.12

@RunWith(SpringRunner.class)
@SpringBootTest
public class SpringBootApplicationTests {

    @Autowired
    private UserService userService;

    @Test
    public void testAddUser() {
      
    }

}
