SpringBoot MockMvcTest - api单元测试

JUnit 简介

JUnit是一款Java语言的单元测试框架，目前大多数Java开发环境都已经支持它了。JUnit测试也就是所谓的白盒测试，在程序员知道程序内部逻辑的基础上进行的测试，使用JUnit能让我们快速地完成单元测试。Spring Boot Test将JUnit和其他测试框架结合起来，提供了便捷高效的测试手段，目前Spring Boot 2.7版本采用的是JUnit 5。

有时候我们接口开发完了，需要在本地进行单元测试，通过MockMvc来实现是个不错的选择，比如，现在有一个JedisTestController：

@Slf4j
@RestController
@RequestMapping("/jedis")
public class JedisController {

    private static final int time_out = 360;

    @PostMapping("/jedisUtilsSetTest")
    public String jedisUtilsSetTest() {

        String stringKey = "stringKey";
        String objectKey = "objectKey";
       
        JedisUtils.getInstance().set(stringKey, "value", time_out);

        AgentIdentityConfig agentIdentityConfig = new AgentIdentityConfig();
        agentIdentityConfig.setId("1");
        agentIdentityConfig.setAgentId("2");
        agentIdentityConfig.setLanguages("232");
        agentIdentityConfig.setRegSwitchStartTime(new Date());
        agentIdentityConfig.setRegSwitchEndTime(new Date());
        agentIdentityConfig.setDefaultPoints(0);
        agentIdentityConfig.setIssuerShortName("2332");
        agentIdentityConfig.setChargePrice(new BigDecimal("0"));
        agentIdentityConfig.setRedeemTimes(0);
        agentIdentityConfig.setCreateTime(new Date());
        agentIdentityConfig.setUpdateTime(new Date());
        JedisUtils.getInstance().setObject(objectKey, agentIdentityConfig, time_out);

        return "jedisUtilsSetTest";
    }


    @GetMapping("/jedisUtilsGetTest")
    public JSONObject jedisUtilsGetTest() {
        JSONObject result = new JSONObject();

        String stringKey = "stringKey";
        String objectKey = "objectKey";
       
        String stringValue = JedisUtils.getInstance().get(stringKey);
        System.out.println("stringValue: " + stringValue);

        AgentIdentityConfig objectValue = (AgentIdentityConfig) JedisUtils.getInstance().getObject(objectKey);
        System.out.println("objectValue: " + objectValue);

        result.put("stringValue", stringValue);
        result.put("objectValue", objectValue);
        return result;
    }
}

在SpringBoot test文件夹下创建JedisMockTest测试类

                .contentType(MediaType.APPLICATION_JSON);
        MvcResult mvcResult = mockMvc.perform(requestBuilder)
                .andExpect(MockMvcResultMatchers.status().isOk())
                .andDo(MockMvcResultHandlers.print())
                .andReturn();
        String response = mvcResult.getResponse().getContentAsString(StandardCharsets.UTF_8);
        System.out.println(response);
    }

    @Test
    @Order(1)
    public void mvcGetTest() throws Exception {
        MockHttpServletRequestBuilder requestBuilder = MockMvcRequestBuilders.get("/jedis/jedisUtilsGetTest")
                .accept(MediaType.APPLICATION_JSON)
                .contentType(MediaType.APPLICATION_JSON);
        MvcResult mvcResult = mockMvc.perform(requestBuilder)

        String response = mvcResult.getResponse().getContentAsString(StandardCharsets.UTF_8);
        System.out.println(response);
    }
}

运行JedisMockTest

测试通过，控制台打印输出内容：
