项目中使用了MockMvcRequestBuilders这个类来实现单元测试
特此举例get和post请求带Cookie,带参数,带对象,表单提交,url路径提交,
针对@ModelAttribute,@RequestBody传参传对象
获取返回对象MockHttpServletRequestBuilder MvcResult ModelAndView,返回视图/json/字符串解析
故作笔记,也方便日后查阅复习.
单元测试框必要的注入都要有,一个小的框架就出来了
@RunWith(SpringRunner.class)
@SpringBootTest
public class domeTest {
@Autowired
private WebApplicationContext context;
protected MockMvc mvc;
@Before
public void setUp() {
mvc = MockMvcBuilders.webAppContextSetup(context).build();
}
@Test
public void doem() {
}
}
1.各种请求入参
//发送请求举例
//post请求
MockHttpServletRequestBuilder post = MockMvcRequestBuilders.post("/test");
//get请求
MockHttpServletRequestBuilder get = MockMvcRequestBuilders.get("/test");
//post请求 带Cookie
MockHttpServletRequestBuilder post_cookie = MockMvcRequestBuilders.post("/test")
.cookie(new Cookie("cookieName","value"));//自己填键值对
//get请求 带Cookie
MockHttpServletRequestBuilder get_cookie = MockMvcRequestBuilders.post("/test")
.cookie(new Cookie("cookieName","value"));//自己填键值对
//post请求 带session
MockHttpServletRequestBuilder post_cookie_session = MockMvcRequestBuilders.post("/test")
.sessionAttr("sessionName","value");
//get请求 带session
MockHttpServletRequestBuilder get_cookie_session = MockMvcRequestBuilders.get("/test")
.sessionAttr("sessionName","value");
//post请求 带Cookie 带参
//另外也可适用场景 使用@ModelAttribute("formName")注解接收form表单对象
//例子:
// @PostMapping("/submitOrder")
// public ModelAndView submitOrder (@ModelAttribute("orderForm") ServiceProductOrder serviceProductOrder)
MockHttpServletRequestBuilder post_cookie_par = MockMvcRequestBuilders.post("/test")
.cookie(new Cookie("cookieName","value"))//自己填键值对
.param("userName","admin")//有@RequestParam注解优先对应,否则对应着表单的input标签的name属性的 值及value
.param("pass","admin");//用@ModelAttribute注解的直接对应表单内容
//get请求 带Cookie 带参方法一(用方法填充)
MockHttpServletRequestBuilder get_cookie_par_one = MockMvcRequestBuilders.post("/test")
.cookie(new Cookie("cookieName","value"))//自己填键值对
//有@RequestParam注解优先对应,否则对应着表单的input标签的name属性的 值及value
.param("userName","admin")
.param("pass","admin");
//get请求 带Cookie 带参方法二(url路径拼接)
MockHttpServletRequestBuilder get_cookie_par_two = MockMvcRequestBuilders.post("/test?userName=admin&pass=admin")
.param("pass","admin");
//post请求 带Cookie
//适用场景:使用@RequestBody注解接收对象
//例子:@PostMapping("/submitOrder")
// public ModelAndView submitOrder (@RequestBody ServiceProductOrder serviceProductOrder) {
Admin admin=new Admin();
admin.setLoginName("admin");
admin.setLoginPassword("admin");//填一些必要的参数等.
MockHttpServletRequestBuilder post_cookie_obj = MockMvcRequestBuilders.post("/test")
.cookie(new Cookie("cookieName","value"))//自己填键值对
.contentType(MediaType.APPLICATION_JSON).content(JSONObject.toJSONString(admin));//阿里巴巴的json序列化
//MultipartFile文件上传请求
String filename = "images/sy_02.png";//测试文件
InputStream inStream = getClass().getClassLoader().getResourceAsStream(filename);
MockMultipartFile mfile = new MockMultipartFile("file", "sy_02.png", "png", inStream);
MockMultipartHttpServletRequestBuilder file = MockMvcRequestBuilders.multipart("/file/upload").file(mfile);
2.各种请求Response处理
上面的代码中都返回了MockHttpServletRequestBuilder(以及文件的MockMultipartHttpServletRequestBuilder)对象,接下来就是执行判断返回内容,这些返回值都继承于RequestBuilder
//执行请求 返回相应的MvcResult (mvc这个参数,看最上面的框架怎么注入的)
//request 就是MockHttpServletRequestBuilder类
MvcResult mvcResult = mvc.perform(request).andReturn();
//获取状态码
int status = mvcResult.getResponse().getStatus();//500状态码 302状态码 404状态码 200状态码等
//获取返回 @ResponseBody json字符串 : 进行反序列化处理即可
//注意: 500/400/302则是返回的HTML源码String类型
String contentAsString = mvcResult.getResponse().getContentAsString();
//返回ModelAndView 获取里面的页面路径
//代码: model.setViewName("/index");
ModelAndView mv = mvcResult.getModelAndView();
String url=mv.getViewName(); //得到/index
//返回ModelAndView 判断里面state参数
// model.addObject("state", 1);
ModelAndView mv = mvcResult.getModelAndView();
Map<String, Object> model = mv.getModel();
Integer state = (Integer) model.get("state");
//返回ModelAndView 判断里面的集合/map/对象
// PageInfo<Admin> list=new PageInfo<>();
// model.addObject("AdminList", list);
ModelAndView mv1 = mvcResult.getModelAndView();
Map<String, Object> model1 = mv1.getModel();
((PageInfo<Admin>) model1.get("AdminList")).getList().size();//得到list长度
ps:返回的json字符串我个人喜欢使用转化为JSONObject再加上Assert断言使用,也挺方便的
JSONObject jsonObject = JSONObject.parseObject(jsonString);
Assert.assertEquals(0,jsonObject.getIntValue("code"));
