在很多Java企业级应用中,Spring占据了非常重要的位置,这就导致了基本上的技术选型都是围绕着Spring来, 比方说笔者最近的项目需要开发一个Restful的API接口,选型的时候就说,客户架构师直接就拍了spring-ws,原因呢?系统中其他的模块都是用的Spring-ws,保持一致,而且社区活跃,文档丰富,遇到问题易解决。好了,入正题。
既然选定了Spring-WS, 已经TDD入魔的我,首先想到的就是我应该怎么测试这个API接口呢? 作为业界最成熟的框架,Spring为测试其Web应用提供了非常好用的辅助类MockMvc。
首先,在项目的测试代码中加入辅助Spring Web测试的库
- testCompile(
- "org.springframework:spring-test:$springVersion",
- "org.springframework.ws:spring-ws-test:2.1.0.RELEASE",
- "javax.servlet:javax.servlet-api:3.0.1",
- "com.jayway.jsonpath:json-path-assert:0.9.0"
- )
其中,jsonpath库的依赖是为了更好的做json格式数据的断言。
然后,编写测试代码
- @RunWith(SpringJUnit4ClassRunner.class)
- @ContextConfiguration(locations = {"classpath:spring-servlet.xml"})
- public class ApiControllerIntegrationTest {
-
- @Autowired
- private ApiController controller;
-
- private MockMvc mockMvc;
-
- @Before
- public void setUp() throws Exception {
-
- mockMvc = MockMvcBuilders.standaloneSetup(controller).build();
- }
-
- @Test
- public void testGet() throws Exception {
-
- mockMvc.perform(get("/requests/1")
- .contentType(MediaType.APPLICATION_JSON)
- .accept(MediaType.APPLICATION_JSON)
- .param("userId", "xianlinbox")
- )
-
-
- .andExpect(status().isOk())
- .andExpect(jsonPath("$.userId").value("xianlinbox"))
- .andExpect(jsonPath("$.requestId").value("1"))
- .andExpect(jsonPath("$.requestType").value("GET"));
- }
-
- @Test
- public void testPost() throws Exception {
- mockMvc.perform(post("/requests")
- .contentType(MediaType.APPLICATION_JSON)
- .accept(MediaType.APPLICATION_JSON)
- .content("this is the message")
- .param("userId", "xianlinbox")
- )
-
-
- .andDo(print())
- .andExpect(status().isCreated())
- .andExpect(jsonPath("$.userId").value("xianlinbox"))
- .andExpect(jsonPath("$.requestType").value("POST"))
- .andExpect(jsonPath("$.message").value("this is the message"));
- }
-
- }
testPost方法中的print()语句打印出的效果如下:
MockHttpServletRequest:
HTTP Method = POST
Request URI = /requests
Parameters = {userId=[xianlinbox]}
Headers = {Content-Type=[application/json], Accept=[application/json]}
Handler:
Type = com.xianlinbox.api.ApiController
Method = public com.xianlinbox.api.Request
com.xianlinbox.api.ApiController.post(java.lang.String,java.lang.String)
Async:
Was async started = false
Async result = null
Resolved Exception:
Type = null
ModelAndView:
View name = null
View = null
Model = null
FlashMap:
MockHttpServletResponse:
Status = 201
Error message = null
Headers = {Content-Type=[application/json;charset=UTF-8]}
Content type = application/json;charset=UTF-8
Body = {"userId":"xianlinbox","requestId":"1","requestType":"POST","message":"this is the message"}
Forwarded URL = null
Redirected URL = null
Cookies = []
看完了测试, 来简单的看下具体的实现代码:
- @Controller
- public class ApiController {
-
- @RequestMapping(value = "/requests/{requestId}", method = RequestMethod.GET)
- @ResponseBody
- public Request get(@PathVariable String requestId, @RequestParam(value = "userId") String userId) {
- return new Request(userId, requestId, "GET");
- }
-
- @RequestMapping(value = "/requests", method = RequestMethod.POST)
- @ResponseBody
- @ResponseStatus(value = HttpStatus.CREATED)
- public Request post(@RequestParam(value = "userId") String userId, @RequestBody String content) {
- Request request = new Request(userId, "1", "POST");
- request.setMessage(content);
- return request;
- }
- }
- 使用RequestMapping定义URL
- 使用@ResponseBody表示返回json
- 使用@PathVariable 获取路径参数
- 使用@RequestParam获取request payload中的参数
- 使用@RequestBody获取request body
- 使用@ResponseStatus(value = HttpStatus.CREATED),定义返回的HTTP STATUS CODE
