QUnit是一个基于JQuery的单元测试Unit Testing 框架。虽然是基于JQuery但用来测试纯Javascript代码。
用来运行Javascript单元测试用例的html页面是这样的：
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>QUnit test runner</title> <link rel="stylesheet" href="lib/qunit-1.10.0.css"> </head> <body> <div id="qunit"></div> <div id="qunit-fixture"></div> <script src="lib/qunit-1.10.0.js"></script> <!--test code goes here--> </body> </html> |
假设我们有如下简单的javascript代码simpleMath.js，实现基本的数学操作，阶乘，平均数。
SimpleMath = function() { }; SimpleMath.prototype.getFactorial = function (number) { if (number < 0) { throw new Error("There is no factorial for negative numbers"); } else if (number == 1 || number == 0) { // If number <= 1 then number! = 1. return 1; } else { // If number > 1 then number! = number * (number-1)! return number * this.getFactorial(number-1); } } SimpleMath.prototype.signum = function (number) { if (number > 0) { return 1; } else if (number == 0) { return 0; } else { return -1; } } SimpleMath.prototype.average = function (number1, number2) { return (number1 + number2) / 2; } |
