本文介绍如何在SpringBoot项目中进行单元测试，重点讲解了如何模拟接口调用以测试业务层代码，包括引入依赖、使用注解及注入bean等关键步骤。

项目上有需求要用到单元测试，并且在未来可能会有代码测试覆盖率的指标，所以提前学习下。其实是只写了业务层的代码实现，可是没有接口，所以想到了通过单元测试来模拟接口调用哈哈

关键点

引入依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-test</artifactId>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>junit</groupId>
    <artifactId>junit</artifactId>
    <version>${junit.version}</version>
    <scope>test</scope>
</dependency>

在测试类上加上注解

@RunWith(SpringRunner.class)
@SpringBootTest
@Slf4j

注入自己需要的bean

private NetworkProxy networkProxy;

@Autowired
public void setNetworkProxy(NetworkProxy networkProxy) {
    this.networkProxy = networkProxy;
}

其实像正常的开发Service那样使用单元测试类就好了

结果

@RunWith(SpringRunner.class)
@SpringBootTest
@Slf4j
public class RestaurantServiceImplTest {

    private NetworkProxy networkProxy;

    @Autowired
    public void setNetworkProxy(NetworkProxy networkProxy) {
        this.networkProxy = networkProxy;
    }

    /**
     * 获取accessToken
     * @return
     */
    public String getAccessToken() {

        HttpHeaders requestHeader = new RequestHeaderUtils.RequestHeaderBuilder()
            .setContentType(MediaType.APPLICATION_FORM_URLENCODED)
            .build().getRequestHeader();

        //body
        MultiValueMap<String, String> requestTokenBody = new RequestBodyUtils.RequestBodyBuilder()
            .setGrantType("xxx")
            .setUsername("xxx")
            .setPassword("xxx;")
            .build().getRequestBody();

        HttpEntity httpEntity = new HttpEntity(requestTokenBody,requestHeader);
        RestaurantRespDTO<TokenRespDTO> result = networkProxy.request(NetworkProxy.Target.RESTAURANT_LOGIN,HttpMethod.POST,httpEntity,
                                                                      new ParameterizedTypeReference<RestaurantRespDTO<TokenRespDTO>>(){}, new HashMap<>());
        log.info("调用登录接口返回 全部消息: " + result);
        log.info("调用登录接口返回 Code 码: " + result.getStatusCode());

        if(result.isSuccess()){

            return result.getData().getAccess_token();

        }else{

            //其他，获取token失败
            log.error("获取token失败: " + result.getStatusMsg());
            throw new BusinessException(Integer.parseInt(result.getStatusCode()),result.getStatusMsg());
        }

    }

    @Test
    public void getxxxIntroduction() {

    }
}
