Postman常用断言

测试天气:用的聚合数据上的免费接口https://www.juhe.cn/    工具:Postman

json接口:

http://apis.juhe.cn/simpleWeather/query?city=武汉&key=******

key值自己在聚合数据网站上获得,填写到这里就可以用

此案例中设置的断言:

pm.test('状态码是200',function(){

  pm.response.to.have.status(200)

}); //断言状态码是200

 

pm.test('响应时间小于500ms',function(){

    pm.expect(pm.response.responseTime).to.be.below(500);

});//响应时间小于500ms

 

var jsonData =JSON.parse(responseBody);

tests['body中的reason结果'] = jsonData.reason ==='查询成功!'    //验证Body里面的内容

tests['body中的city是否正确'] = jsonData.result.city ==='武汉'      //验证body中的城市是否正确

 

//验证是不是从当天开始的

pm.test('验证body中的第一天天气是否为当天的',function(){

    var jsonData = pm.response.json();

    pm.expect(jsonData.result.future[0].date) ==='2020-06-15'   //后面验证的需要改此处的时间

});

postman常见断言方法介绍:

 

Setting an environment variable  (设置一个环境变量)

1

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

  

Setting a nested object as an environment variable (将嵌套对象设置为环境变量)

1

2

3

4

5

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));

  

Getting an environment variable (获取环境变量)

1

pm.environment.get("variable_key");

  

Getting an environment variable (whose value is a stringified object)  获取一个环境变量(其值是一个字符串化的对象)

1

2

4

// 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"));

  

Clear an environment variable (清除一个环境变量)

1

pm.environment.unset("variable_key");

  

Set a global variable (设置一个全局变量)

1

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

  

Get a global variable (获取一个全局变量)

1

pm.globals.get("variable_key");

  

Clear a global variable (清除全局变量)

1

pm.globals.unset("variable_key");

  

Get a variable (获取一个变量)

该函数在全局变量和活动环境中搜索变量。

1

pm.variables.get("variable_key");

  

Check if response body contains a string (检查响应主体是否包含字符串)

1

2

3

pm.test("Body matches string"function () {

    pm.expect(pm.response.text()).to.include("string_you_want_to_search");

});

  

Check if response body is equal to a string (检查响应主体是否等于一个字符串)

1

2

3

pm.test("Body is correct"function () {

    pm.response.to.have.body("response_body_string");

});

  

Check for a JSON value (检查JSON值

1

pm.test("Your test name"function () {

    var jsonData = pm.response.json();

    pm.expect(jsonData.value).to.eql(100);

});

  

Content-Type is present (内容类型存在

1

2

3

pm.test("Content-Type is present"function () {

    pm.response.to.have.header("Content-Type");

});

  

Response time is less than 200ms (响应时间小于200ms

1

2

3

pm.test("Response time is less than 200ms"function () {

    pm.expect(pm.response.responseTime).to.be.below(200);

});

  

Status code is 200 (状态码是200

1

2

3

pm.test("Status code is 200"function () {

    pm.response.to.have.status(200);

});

  

Code name contains a string (代码名称包含一个字符串

1

2

3

pm.test("Status code name has string"function () {

    pm.response.to.have.status("Created");

});

  

Successful POST request status code (成功的POST请求状态码

1

2

3

pm.test("Successful POST request"function () {

    pm.expect(pm.response.code).to.be.oneOf([201,202]);

});

var schema = {

};

var data1 = [truefalse];

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;

});

  

Decode base64 encoded data (解码base64编码的数据

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

});

  

Send an asynchronous request (发送异步请求

该功能既可以作为预先请求,也可以作为测试脚本使用。

pm.sendRequest("https://postman-echo.com/get"function (err, response) {

    console.log(response.json());

});

  

Convert XML body to a JSON object (将XML正文转换为JSON对象

var jsonObject = xml2Json(responseBody);
