Postman-Tests模块测试方法记录

  •  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

var jsonObject = xml2Json(responseBody);

-----------------------------------------------------------------------------------------------------------------------------

1. 清除一个全局变量
Clear a global variable
对应脚本:
postman.clearGlobalVariable("variable_key");
参数:需要清除的变量的key

2.清除一个环境变量
Clear an environment variable
对应脚本:
postman.clearEnvironmentVariable("variable_key");
参数:需要清除的环境变量的key

3.response包含内容
Response body:Contains string
对应脚本:
tests["Body matches string"] =responseBody.has("string_you_want_to_search");
参数:预期内容

4.将xml格式的response转换成son格式
Response body:Convert XML body to a JSON Object
对应脚本:
var jsonObject = xml2Json(responseBody);
参数:(默认不需要设置参数,为接口的response)需要转换的xml

5.response等于预期内容
Response body:Is equal to a string
对应脚本:
tests["Body is correct"] = responseBody === "response_body_string";
参数:预期response

6.json解析key的值进行校验
Response body:JSON value check
对应脚本:
tests["Args key contains argument passed as url parameter"] = 'test' in responseJSON.args
参数:test替换被测的值,args替换被测的key

7.检查response的header信息是否有被测字段
Response headers:Content-Type header check
对应脚本:
tests["Content-Type is present"] = postman.getResponseHeader("Content-Type");
参数:预期header

8.响应时间判断
Response time is less than 200ms
对应脚本:
tests["Response time is less than 200ms"] = responseTime < 200;
参数:响应时间

9.设置全局变量
Set an global variable
对应脚本:
postman.setGlobalVariable("variable_key", "variable_value");
参数:全局变量的键值

10.设置环境变量
Set an environment variable
对应脚本:
postman.setEnvironmentVariable("variable_key", "variable_value");
参数:环境变量的键值

11.判断状态码
Status code:Code is 200
对应脚本:
tests["Status code is 200"] = responseCode.code != 400;
参数:状态码

12.检查code name 是否包含内容
Status code:Code name has string
对应脚本:
tests["Status code name has string"] = responseCode.name.has("Created");
参数:预期code name包含字符串

13.成功的post请求
Status code:Successful POST request
对应脚本:
tests["Successful POST request"] = responseCode.code === 201 || responseCode.code === 202;

14.微小验证器
Use Tiny Validator for JSON data
对应脚本:
var schema = {
"items": {
"type": "boolean"
}
};
var data1 = [true, false];
var data2 = [true, 123];
console.log(tv4.error);
tests["Valid Data1"] = tv4.validate(data1, schema);
tests["Valid Data2"] = tv4.validate(data2, schema);
参数:可以修改items里面的键值对来对应验证json的参数
