概述

@SpringBootTest注解是SpringBoot Since:1.4.0 版本开始引入的一个用于测试的注解。基本用法如下：

添加的依赖

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

需要测试的类

    @GetMapping("/health")
    public String health() {
        return HttpStatus.OK.getReasonPhrase();
    }

单元测试类

/**
 * @Description TODO
 * @Date 2019/5/5 11:37
 */
@RunWith(SpringRunner.class)
@SpringBootTest
@AutoConfigureMockMvc
public class HealthControllerTest {

    @Autowired
    private MockMvc mvc;

    @Test
    public void testHealth() throws Exception {

        this.mvc.perform(MockMvcRequestBuilders.get("/health")).andExpect(status().isOk())
                .andExpect(MockMvcResultMatchers.content().string("OK"));

    }
}
