The higher your test coverage, the more flexible and bug-resistant your code will be, and the less time you’ll spend debugging hot fixes in production.javascript
測試覆蓋率越高,代碼就越靈活,生產中調試修補程序所花費的時間就越少。java
首先,很遺憾的一點是,Postman不支持併發測試,但支持指定次數與間隔時間的串行測試。npm
官方文檔連接:Postman Test scriptsjson
測試容許配置在Collections/Folder/Request中,配置在Collections/Folder中方便咱們統一的對多接口進行測試。api
Postman Test 是在接受到請求響應Response後執行的一段JavaScript代碼。在發送請求並從服務器收到響應後Postman將運行測試腳本。。在Postman Request Builder中,請求部分包含一個Tests標籤,返回部分包含一個Test Result標籤。
在Tests標籤右邊,羅列了一些輔助編寫的經常使用代碼段。服務器
pm.test()
函數可以在Postman test Sandbox中編寫測試規範。使用此函數容許你準確命名某個測試,而且確保測試腳本中的某個錯誤並不會阻塞其他部分的執行。pm.test()
接受兩個參數:(string testName, A Function witch resturn boolean value).// example using pm.response.to.have pm.test("response is ok", function () { pm.response.to.have.status(200); }); // example using pm.expect() pm.test("environment to be production", function () { pm.expect(pm.environment.get("env")).to.equal("production"); }); // example using response assertions pm.test("response should be okay to process", function () { pm.response.to.not.be.error; pm.response.to.have.jsonBody(""); pm.response.to.not.have.jsonBody("error"); }); // example using pm.response.to.be* pm.test("response must be valid and have a body", function () { // assert that the status code is 200 pm.response.to.be.ok; // info, success, redirection, clientError, serverError, are other variants // assert that the response has a valid JSON body pm.response.to.be.withBody; pm.response.to.be.json; // this assertion also checks if a body exists, so the above check is not needed });
### pm.* 輔助函數網絡
須要命令行工具與持續集成工具或持續交付工具(如Jenkins或Travis CI)集成來自動化您的測試。併發
//設置環境變量 pm.environment.set("variable_key", "variable_value"); //將嵌套對象設置爲環境變量 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)); //獲取環境變量 pm.environment.get("variable_key"); //獲取環境變量(其值是字符串化對象) // 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")); //清除環境變量 pm.environment.unset("variable_key"); //設置全局變量 pm.globals.set("variable_key", "variable_value"); //獲取全局變量 pm.globals.get("variable_key"); //清除全局變量 pm.globals.unset("variable_key"); //獲取變量:此函數在全局變量和活動環境中搜索變量 pm.variables.get("variable_key"); //檢查響應主體是否包含字符串 pm.test("Body matches string", function () { pm.expect(pm.response.text()).to.include("string_you_want_to_search"); }); //檢查響應主體是否等於字符串 pm.test("Body is correct", function () { pm.response.to.have.body("response_body_string"); }); //檢查JSON值 pm.test("Your test name", function () { var jsonData = pm.response.json(); pm.expect(jsonData.value).to.eql(100); }); //Content-Type是否存在 pm.test("Content-Type is present", function () { pm.response.to.have.header("Content-Type"); }); //響應時間小於200毫秒 pm.test("Status code is 200", function () { pm.response.to.have.status(200); }); //Code name contains a string: 檢查Code name包含指定string。網絡基礎知識很差,不太理解這一句話Orz pm.test("Status code name has string", function () { pm.response.to.have.status("Created"); }); //成功的POST請求狀態代碼 pm.test("Successful POST request", function () { pm.expect(pm.response.code).to.be.oneOf([201,202]); }); //使用TinyValidator獲取JSON數據 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; }); //解碼base64編碼數據 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 }); //發送異步請求 pm.sendRequest("https://postman-echo.com/get", function (err, response) { console.log(response.json()); }); //將XML主體轉換爲JSON對象 var jsonObject = xml2Json(responseBody);
