postman斷言

postman斷言是JavaScript語言編寫的，在postman客戶端的test區域編寫便可，
斷言會在請求返回以後，運行，並根據斷言的pass\fail狀況體如今最終測試結果中。
斷言以下：
1.設置環境變量--Setting an environment variable
postman.setEnvironmentVariable("key", "value");
2.設置全局變量--Set a global variable
postman.setGlobalVariable("key", "value");
3.檢查響應中包含string--Check if response body contains a string
tests["Body matches string"] = responseBody.has("string_you_want_to_search");
4.轉化XML格式的響應成JSON對象---Convert XML body to a JSON object
var jsonObject = xml2Json(responseBody);
5.檢查響應body中等於指定string--Check if response body is equal to a string
tests["Body is correct"] = responseBody === "response_body_string";6.檢查JSON某字段值--Check for a JSON value
var data = JSON.parse(responseBody);
tests["json test"] = data.showDes === "0001";
針對JSON數據：tests["aaa"] = data.books[0].pubdate === "1972年4月";
7.檢查Content-Type是否包含在header返回（大小寫不敏感）--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.檢查Content-Type是否包含在header返回（大小寫敏感）--Content-Type is
present (Case-sensitive)
tests["Content-Type is present"] = responseHeaders.hasOwnProperty("Content-
Type");
9.檢查請求耗時時間小於200ms--Response time is less than 200ms
tests["Response time is less than 200ms"] = responseTime < 200;
10.檢查Status code爲200--Status code is 200
tests["Status code is 200"] = responseCode.code === 200;
11.檢查Code name包含指定string--Code name contains a string
tests["Status code name has string"] = responseCode.name.has("Created");
12.檢查成功post的請求status code--Succesful
