Postman batch test interface detailed tutorial

介绍

postman是一个谷歌出的轻量级的专门测试接口的小工具,虽然不如 firefox 的 poster 插件“轻量”,但是比 firefox 的 poster 插件、fiddler The interface test function is more comprehensive,比 Jmeter 更轻量、便捷~

postman 包括两种：Chrome 浏览器插件和 postman 客户端,我使用的是 postman 客户端

我比较喜欢postmantwo function points,One is its batch execution、One is its view source function.

今天分享的是postman如何批量执行接口测试用例,This will bring a lot of convenience to our work,比如我们写了几十个测试用例,Requests are all to the same address,但参数不同！postmanHelp us solve this problem perfectly.

需求

I am going to access an interface,参数da为20220701到20220731一个月的时间,即发送31次请求.就可以利用postman实现,See below for specific operations.

实践

新建一个名为batchDateAdd的请求.访问的 GET 请求接口为：

http://blog.liabio.cn?da={
    {
    da}}

这里的{ {da}}是变量占位符,will be filled with the actual value from the environment variable.

在 Tests Add scripts to tabs：

脚本内容如下：

var moment = require('moment');

var Num = pm.environment.get("Num");

var data = moment("2022-07-01").add(Num, "days").format("YYYYMMDD");
pm.environment.set("da", data);

Num++
pm.environment.set("Num", Num);

注意：这里用到 momentjs

新建一个名为testEnvThe environment variable group of.The environment sets the initial valueda为20220701,Num为1：

Will be used for the first requestdaThis value populates the placeholder.At the same time, the above script will be executed,将da值和Num 值修改,The modified value will be used next time.

Start a batch run,Click on the folderRun collection：

Check the interface to be tested,and set the number of cycles,Each loop delay interval, etc,Here we enter the number of loops as 31,点击 Run：

注意：请输入31,This and the screenshot1不匹配

脚本中如果有console.log("hello")can be viewed in the console,The way to open the console isView -> Show Postman Console：

During the execution of the script, the environment variables are dynamically modifiedNum和da的Current Value值：

After each test run,需要点击Reset All,将Current Value重置为Initial Value：

Otherwise the next run will beCurrent Value作为初始值.
