postman使用心得（二）：postman接口测试断言

在使用postman做接口测试的时候，可以在tests中对该接口进行断言设置

json字符串解析断言

上面的图为使用postman断言方法之一，使json解析key的值进行校验

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

其中 Your test name 为断言名，jsonData.value表示为对json进行解析，=== 100 表示为key的value值

{
  "ok": true,
  "data": {
    "user": {
      "user_no": "888",
      "type": "1",
      "user_name": "W HE",
      "fullname": "W HE",
      "nickname": "",
      "login_name": "[email protected]",
      "headimg": "",
      "is_payed": true,
      "is_certified": false
    },
    "redirect_url": "/team/search"
  }
}

jsonData["data"]["user"]["user_name"] === "W HE"

附：

常用的postman断言	解释	对应脚本
Response body:Contains string	response包含字符串	tests["Body matches string"] = responseBody.has("string_you_want_to_search");
Response body:Is equal to a string	response body等于指定字符串	tests["Body is correct"] = responseBody === "response_body_string";
response body:JSON value check	json解析key的值进行校验	tests["Your test name"] = jsonData.value === 100;
status code:Code is 200	判断状态码	tests["Status code is 200"] = responseCode.code === 200;
status code:code name has string	检查code name 是否包含内容	tests["Status code name has string"] = responseCode.name.has("Created");
