Postman断言（Tests）语句基础使用教程[憧憬]

(绿色星星)：常用语句 (星星)：功能重复 灰色：不常用

区别在于：Pre-request Script是在request之前就会执行代码，而Tests是在request和response结束后的断言区域

(绿色星星) 0、把responseBody值转为JSON格式赋给yue

  var yue = JSON.parse(responseBody)

(绿色星星) 1、设置环境变量–Setting an environment variable

    postman.setEnvironmentVariable("key", "value");

(绿色星星) 2、设置全局变量–Set a global variable

    postman.setGlobalVariable("key", "value");

(绿色星星) 3、检查响应中是否包含字符串XXX–Check if response body contains a string

    tests["Body matches string"] = responseBody.has("string_you_want_to_search");

4、转化XML格式的响应成JSON对象—Convert XML body to a JSON object

    var jsonObject = xml2Json(responseBody);

5、检查响应body中等于指定string–Check if response body is equal to a string

    tests["Body is correct"] = responseBody === "response_body_string";

(绿色星星) 6、检查JSON某字段的值–Check for a JSON value

    var data = JSON.parse(responseBody);

    tests["Your test name"] = data.value === 100；

    数组取法：tests["1111"]= yueqiang.data.schoolList[0].id===91;

7、检查Content-Type是否包含在header返回（大小写不敏感）–Content-Type is present (Case-insensitive checking)

    tests["Content-Type is present"] = postman.getResponseHeader("Content-Type"); //Note: the getResponseHeader() method returns the header value, if it exists.

8、检查Content-Type是否包含在header返回（大小写敏感）–Content-Type is present (Case-sensitive)

    tests["Content-Type is present"] = responseHeaders.hasOwnProperty("Content-Type");

(绿色星星) 9、检查请求耗时时间小于200ms–Response time is less than 200ms

   tests["Response time is less than 200ms"] = responseTime < 200;

(绿色星星) 10、检查Status code为200–Status code is 200

   tests["Status code is 200"] = responseCode.code === 200;

(星星) 11、检查Code name是否指定string–Code name contains a string

   tests["Status code name has string"] = responseCode.name.has("Created");

(星星) 12、检查成功post的请求status code–Succesful POST request status code

   tests["Successful POST request"] = responseCode.code === 201 || responseCode.code === 202;

(绿色星星)13、获取数组里最后一条记录

   var yue=JSON.parse(responseBody);
   postman.setEnvironmentVariable("smart-classid",yue.data.formal[yue.data.formal.length-1].id);
