postman 断言解析

最近在学习postman官方文档， 顺势翻译出来，以供学习！

postman断言是JavaScript语言编写的，在postman客户端指定区域编写即可。

断言会在请求返回之后，运行，并根据断言的pass\fail情况体现在最终测试结果中。

1.设置环境变量--Setting an environment variable

postman.setEnvironmentVariable("key", "value");

2.设置全局变量--Set a global variable

postman.setGlobalVariable("key", "value");

3.检查响应中包含string--Check if response body contains a string

tests["Body matches string"] = responseBody.has("string_you_want_to_search");

4.转化XML格式的响应成JSON对象---Convert XML body to a JSON object

var jsonObject = xml2Json(responseBody);

5.检查响应body中等于指定string--Check if response body is equal to a string

tests["Body is correct"] = responseBody === "response_body_string";

6.检查JSON某字段值--Check for a JSON value

var data = JSON.parse(responseBody);

tests["Your test name"] = data.value === 100;

7.检查Content-Type是否包含在header返回（大小写不敏感）--Content-Type is present (Case-insensitive checking)

tests["Content-Type is present"] = postman.getResponseHeader("Content-Type"); //Note: the getResponseHeader() method returns the header value, if it exists.

8.检查Content-Type是否包含在header返回（大小写敏感）--Content-Type is present (Case-sensitive)

tests["Content-Type is present"] = responseHeaders.hasOwnProperty("Content-Type");

9.检查请求耗时时间小于200ms--Response time is less than 200ms

tests["Response time is less than 200ms"] = responseTime < 200;

10.检查Status code为200--Status code is 200

tests["Status code is 200"] = responseCode.code === 200;

11.检查Code name包含指定string--Code name contains a string

tests["Status code name has string"] = responseCode.name.has("Created");

12.检查成功post的请求status code--Succesful POST request status code

tests["Successful POST request"] = responseCode.code === 201 || responseCode.code === 202;

13.为JSON data使用微小验证器--Use TinyValidator for JSON data

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);

Sample data files

JSON files are composed of key/value pairs
