Qunit的使用
1.新建一个html页面,如下
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Collection Test</title> <link rel="stylesheet" href="SlickGrid/lib/qunit.css" type="text/css"/> <script type="text/javascript" src="SlickGrid/lib/qunit.js"> </script> <script type="text/javascript" src="collections.js"> </script> <script type="text/javascript" src="ArrayListTest.js"> </script> <script type="text/javascript" src="MapTest.js"> </script> </head> <body> <h1 id="qunit-header">ArrayList And Map Test</h1> <h2 id="qunit-banner"></h2> <h2 id="qunit-userAgent"></h2> <ol id="qunit-tests"> </ol> <div id="qunit-fixture"> </div> </body> </html>
在页面中引入qunit.js和qunit.css, 可以去官网下载:http://qunitjs.com/
引入你要测试的js
// 封装ArrayList类,用法与java类似。 (function(win){ var ArrayList = function(array){ var datas = []; this.setDatas = function(value){ datas = value; }; this.getDatas = function(){ return datas; }; if (array && Object.prototype.toString.call(array) === "[object Array]") { this.setDatas(array);

引入你将要编写的测试的js
body里的内容固定如上图。
2.写自己的测试代码

module有两个主要的方法:setup和teardown, 分别是在方法调用前和调用后执行。
test("", function(){}); 表示执行一个测试用例
用于诊断的方法主要有:equals、equal、same、deepEqual、notEqual、notDeepEqual、strictEqual、notStrictEqual、ok、expect
详细用法见官方文档。
