Postman中的测试脚本（Test scripts）

一、postman测试脚本

测试脚本是在发送请求之后运行的，并且已经从服务器接收到响应。

二、测试举例

1、设置环境变量

pm.environment.set("variable_key", "variable_value");

2、将嵌套对象设置为环境变量

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));

3、获取环境变量

pm.environment.get("variable_key");

4、获取环境变量（其值是严格化对象）

var array = JSON.parse(pm.environment.get("array"));
var obj = JSON.parse(pm.environment.get("obj"));

5、清除环境变量

pm.environment.unset("variable_key");

6、设置全局变量

pm.globals.set("variable_key", "variable_value");

7、获取全局变量

pm.globals.get("variable_key");

8、清除全局变量

pm.globals.unset("variable_key");

9、获取变量

pm.variables.get("variable_key");

10、检查响应体是否包含字符串

pm.test("Body matches string", function () {
    pm.expect(pm.response.text()).to.include("string_you_want_to_search");
});

11、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");
});

12、检查JSON值

pm.test("Your test name", function () {
    var jsonData = pm.response.json();
    pm.expect(jsonData.value).to.eql(100);
});

13、内容类型存在

pm.test("Content-Type is present", function () {
    pm.response.to.have.header("Content-Type");
});

14、响应时间小于200毫秒

pm.test("Response time is less than 200ms", function () {
    pm.expect(pm.response.responseTime).to.be.below(200);
});

15、状态代码为200

pm.test("Status code is 200", function () {
    pm.response.to.have.status(200);
});

16、代码名包含字符串

pm.test("Status code name has string", function () {
    pm.response.to.have.status("Created");
});

17、成功后请求状态代码

pm.test("Successful POST request", function () {
    pm.expect(pm.response.code).to.be.oneOf([201,202]);
});

18、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;
});

19、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
});

20、发送异步请求

pm.sendRequest("https://postman-echo.com/get", function (err, response) {
    console.log(response.json());
});

21、将XML体转换为JSON对象

var jsonObject = xml2Json(responseBody);
