PostMan Test scripts使用方法

测试脚本是在发送请求之后并且从服务器接收到响应时执行。

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200mspm.test("Response time is less than 200ms", function () {    pm.expect(pm.response.responseTime).to.be.below(200);});状态码是200pm.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TinyValidatorvar 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-jspm.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var jsonObject = xml2Json(responseBody);
