随机

1.请求参数变化

 postman中可以使用randomInt达到每次运行的参数都是变化的

/*  使用者变量信息---重用的随机构造  */

const   randomInt = (min,max) =>Math.floor(Math.random() * (max-min+1))+min; //随机整数
const   getRandomValue = list =>list[randomInt(0,list.length-1)];      //随机选项

实现用户姓名、呢称、身份证和手机号以及输入性别的随机输入操作，代码如下

/*  使用者变量信息  */

const   randomInt = (min,max) => Math.floor(Math.random() * (max-min+1))+min;    //随机整数
const   getRandomValue = list =>list=>list[randomInt(0,list.length-1)];       //随机选项

//随机生成一个字符串作为用户名
postman.setGlobalVariable("compellation",("0000" + (Math.random() * Math.pow(36,7)<<0).toString(36)).slice(-7);

//用户昵称，随机2-6字姓名
const  charsInName = ['赵','钱','孙','李','王','张']；
const  numOfChars = randomInt(2,6);
let  randomName='';
for (let i=0;i<numOfChars;i++) {
let  index = randomInt(0,5);
randomName += charsInName[index];
}
//environment.nickname=randomName;
postman.setGlobalVariable("nickname",randomName);

/**
//随机生成一个字符串作为昵称
postman.setEnvironmentVarible("nickname",("0000" +(Math.random()*Math.pow(36,4)<<0).toString(36)).slice(-4));

*/
//用户性别

const  divisions = ['O','M','F'];
  //为什么使用environment无法设置变量？原因environment是引起环境变量的操作
  //environment.sex=getRandomValue(divisions);
postman.setGlobalVariable("sex",getRandomValue(divisions));
  //postman.setEnvironmentVariable("sex","O");
  //用户身份证号码
  //postman.setEnvironmentVariable("card","500106200412055816")
postman.setGlobalVariable("card",'50010620001208${randomInt(1000,9999)}');
  //随机生日（时间戳）
  //假设今天是2017-1-1，距离1970-1-1  47年，则生日范围为 1923-1-1 ~ 2017-1-1
  //environment.birthday = randomInt(0-Date.now(),Date.now());
  //postman.setEnvironmentVariable("birthday",Date.now());
 /**
  //获取当前系统时间，并组装成固定格式时间戳
  var d= new Date();
  //将日期组装成2位
  var  timeDate = d.getDate().toString();
  if(timeDate.length ==1){
  timeData ='0'+ timeData;
}
  //组装整个时间戳
  var timesData = d.getFullYear() +"-"+(dgetMonth()+1).toString() +"-"+timeData;
  postman.setEnvironmentVariable("birthady",timesData);
  */
postman.setGlobalVariable("birthday",'2000-12-08');
  //身高
  //environment.height = '${randomInt(120,221)}'
  //environment.height = randomInt(120,221);
postman.setGlobalVariable("height",randomInt(120,221));
  //体重
  //environment.weight = '${randomInt(40, 150)}';
  //environment.height = randomInt(40, 150);
postman.setGlobalVariable("weight",randomInt(40, 150));
 //remark
 //随机生成一个字符串作为remark
postman.setGlobalVariable("remark",("test"+(Math.random() * Math.pow(36,4)<<0).toString(36)).slice(-4));
 // 随机手机
 //environment.phone = `18${randomInt(100000000, 999999999)}`;
postman.setGlobalVariable("phone",`18${randomInt(100000000, 999999999)}`);

这样就实现了接口的参数化，那么录入用户的接口Pre-Request Script代码如下:

//获取全局变量值
sessionId = postman.getGlobalVariable("sessionId");
customerCode = postman.getGlobalVariable("customerCode");
timestamp = postman.getGlobalVariable('timestamp');
ytoken = postman.getGlobalVariable("ytoken");
unicode = postman.getGlobalVariable("unicode");
var pytokenstr = sessionId + customerCode+unicode+timestamp+ytoken;

//postman.setEnvironmentVariable("str",str);
//environment.str = str;
postman.setGlobalVariable("pytokenstr",pytokenstr);
//var md5 = CryptoJS.MD5(str).toString().toLowerCase();
//使用md5加密得到ptoken
//var strmd5 = CryptoJS.MD5(str).toString();
var ptoken = CryptoJS.MD5(pytokenstr);
//environment.strmd5 = strmd5;
postman.setGlobalVariable('ptoken',ptoken);

/**使用者变量信息   */

const randomInt = (min, max) => Math.floor(Math.random() * (max - min + 1)) + min;  // 随机整数
const getRandomValue = list => list[randomInt(0, list.length - 1)];  // 随机选项
//随机生成一个字符串作为用户名 
postman.setGlobalVariable("compellation", ("0000" + 
(Math.random()*Math.pow(36,7) << 0).toString(36)).slice(-7));

//用户昵称，随机2-6字姓名
const charsInName = ['赵', '钱', '孙', '李', '王', '张'];
const numOfChars = randomInt(2, 6);
let randomName = '';
for (let i = 0; i < numOfChars; i++) {
let index = randomInt(0, 5);
randomName += charsInName[index];
}
//environment.nickname = randomName;
postman.setGlobalVariable("nickname",randomName);

/**
//随机生成一个字符串作为昵称 
postman.setEnvironmentVariable("nickname", ("0000" + 
(Math.random()*Math.pow(36,4) << 0).toString(36)).slice(-4));
    */
//用户性别
const divisions = ['O', 'M', 'F'];
//为什么使用environment无法设置变量? 原因environment是引用环境变量的操作
//environment.sex = getRandomValue(divisions);
postman.setGlobalVariable("sex",getRandomValue(divisions));
//postman.setEnvironmentVariable("sex","O");
//用户身份证号码
//postman.setEnvironmentVariable("card","500106200412055816");
postman.setGlobalVariable("card",`50010620001208${randomInt(1000, 9999)}`);
// 随机生日（时间戳）
// 假设今天是2017-1-1，距1970-1-1 47年，则生日范围为 1923-1-1 ~ 2017-1-1
//environment.birthday = randomInt(0 - Date.now(), Date.now());
//postman.setEnvironmentVariable("birthday",Date.now());
/**
//获取系统当前时间，并组装成固定格式时间戳
var d = new Date();
//将日期组装成2位
var timeDate = d.getDate().toString();
if(timeDate.length == 1){
timeDate = "0" + timeDate;
}
//组装整个时间戳
var timesDate = d.getFullYear() + "-"+(d.getMonth()+1).toString() +"-"+ timeDate; 
postman.setEnvironmentVariable("birthday", timesDate);
    */
postman.setGlobalVariable("birthday", '2000-12-08');
//身高
//environment.height = '${randomInt(120, 221)}';
//environment.height = randomInt(120, 221);
postman.setGlobalVariable("height",randomInt(120, 221));
//体重
//environment.weight = '${randomInt(40, 150)}';
//environment.height = randomInt(40, 150);
postman.setGlobalVariable("weight",randomInt(40, 150));
//remark
//随机生成一个字符串作为remark 
postman.setGlobalVariable("remark", ("test" + 
(Math.random()*Math.pow(36,4) << 0).toString(36)).slice(-4));
// 随机手机
//environment.phone = `18${randomInt(100000000, 999999999)}`;
postman.setGlobalVariable("phone",`18${randomInt(100000000, 999999999)}`);
console.log(pytokenstr);

之后在Tests中增加断言信息，代码如下:

// 推荐用全等 ===，确保类型和值都一致
//tests['Status code is 200'] = responseCode.code === 200); 
// 判断是否存在 'success' 值  
if(responseCode.code===200 & responseBody !== null & responseBody.has("code") ){
tests["Body matches code"] = responseBody.has("0");

var jsonData = JSON.parse(responseBody);
postman.setGlobalVariable("userId",jsonData.result.user_id);

tests[`[INFO] Request params: ${JSON.stringify(request.data)}`] = true;
//可以考虑判断user_id，后续升级考虑
tests["have result "]=jsonData.hasOwnProperty("result")===true;
tests[`[INFO] Response timeout: ${responseTime}`] = responseTime < 6000;

}
else{
//接口请求失败
tests["Waring：Request Failed. Please Fix!"] = false;
}

在上面这段代码中，使用var jsonData = JSON.parse(responseBody); postman.setGlobalVariable("userId",jsonData.result.user_id);再次获取了该接口的响应结果中的user_id的值作为下一个接口的参数，而该接口的响应结果代码如图

{
"result": {
    "birthday": "2000-12-08",
    "phone": "18271263485",
    "sex": "O",
    "register_time": "2017-11-30 10:49:43",
    "weight": "109",
    "height": "184",
    "remark": "fdn1",
    "organization_id": "1149",
    "compellation": "-pm6eil",
    "card": "500106200012081705",
    "user_id": 1638
},
"code": "0"
}

1.客户姓名自动生成

//自动生成随机姓名
function  getName(){
 var familyNames =  new Array("赵", "钱", "孙", "李", "王", "张");  
 var giveNames =  new Array("哈", "一", "二", "三", "四", "五"); 

 var  i=parseInt(10*Math.random())；
 var  familyNames = familyNames [1]; 

 var  j=parseInt(10*Math.random())；
 var  giveNames = giveNames [1]; 
 var nickname=familyNames +giveNames ;
 return  nickname;
    }

getName（）
>>李夫子

2.客户手机号码自动生成

//自动化生成随机手机号
function  getMobleNumber(){
 var prefixArray=  new Array("130", "131", "150", "151", "138", "170","189");  
 var  i=parseInt(10*Math.random())；
 var  prefix= prefixArray[1]; 

 for(var  j=0;j<8;J++){
      prefix = prefix +Math.floor(Math.random()*10);
}
  return  prefix
}

getMobleNumber()
