PostMan Test 的脚本scripts编写方法

 设置环境变量
 pm.environment.set("variable_key", "variable_value");
 
 将一个嵌套的对象设置为一个环境变量
 var array = [1, 2, 3, 4];
 pm.environment.set("array", JSON.stringify(array, null, 2));
 
 var obj = { a: [1, 2, 3, 4], b: { c: 'val' } };
 pm.environment.set("obj", JSON.stringify(obj))
 
 获得一个环境变量
 pm.environment.get("variable_key");
 
 获得一个环境变量(其值是一个字符串化的对象)
 // These statements should be wrapped in a try-catch block if the data is coming from an unknown source.
 var array = JSON.parse(pm.environment.get("array"));
 var obj = JSON.parse(pm.environment.get("obj"));
 
 清除一个环境变量
 pm.environment.unset("variable_key");
 
 设置一个全局变量
 pm.globals.set("variable_key", "variable_value");
 
 获取一个全局变量
 pm.globals.get("variable_key");
 
 清除一个全局变量
 pm.globals.unset("variable_key");
 
 获取一个变量
 该函数在全局变量和活动环境中搜索变量
 pm.variables.get("variable_key");
 
 检查响应主体是否包含字符串
 pm.test("Body matches string", function () {
     pm.expect(pm.response.text()).to.include("string_you_want_to_search");
 });
 
 检查响应体是否等于字符串
 pm.test("Body is correct", function () {
     pm.response.to.have.body("response_body_string");
 });
 
 检查JSON值
 pm.test("Your test name", function () {
     var jsonData = pm.response.json();
     pm.expect(jsonData.value).to.eql(100);
 });
 
 Content-Type 存在
 pm.test("Content-Type is present", function () {
     pm.response.to.have.header("Content-Type");
 });
 
 返回时间少于200ms
 pm.test("Response time is less than 200ms", function () {
     pm.expect(pm.response.responseTime).to.be.below(200);
 });
 
 状态码是200
 pm.test("Status code is 200", function () {
     pm.response.to.have.status(200);
 });
 
 代码名包含一个字符串
 pm.test("Status code name has string", function () {
     pm.response.to.have.status("Created");
 });
 
 成功的POST请求状态码
 pm.test("Successful POST request", function () {
     pm.expect(pm.response.code).to.be.oneOf([201,202]);
 });
 
 为JSON数据使用TinyValidator
 var schema = {
  "items": {
  "type": "boolean"
  }
 };
 var data1 = [true, false];
 var data2 = [true, 123];
 
 pm.test('Schema is valid', function() {
   pm.expect(tv4.validate(data1, schema)).to.be.true;
   pm.expect(tv4.validate(data2, schema)).to.be.true;
 });
 
 解码base64编码数据
 var intermediate,
     base64Content, // assume this has a base64 encoded value
     rawContent = base64Content.slice('data:application/octet-stream;base64,'.length);
 
 intermediate = CryptoJS.enc.Base64.parse(base64content); // CryptoJS is an inbuilt object, documented here: https://www.npmjs.com/package/crypto-js
 pm.test('Contents are valid', function() {
   pm.expect(CryptoJS.enc.Utf8.stringify(intermediate)).to.be.true; // a check for non-emptiness
 });
 
 发送异步请求
 此函数可作为预请求和测试脚本使用
 pm.sendRequest("https://postman-echo.com/get", function (err, response) {
     console.log(response.json());
 });
 
 将XML主体转换为JSON对象
