用过JUnit的朋友，可能一看就明白了。
没有用过的，估计也不会有太大问题。
好了废话不说，返回正题。
1。 怎么使用写测试函数
简单例子
JSUnitTest.prototype.testAdd = function(){
this.assertEquals("3", 1+2);
}
只需要扩展JSUnitTest.prototype就可以。（当然必须是function）
2。我在测试前由一些初始工作要做，怎么办？
扩展
JSUnitTest.prototype.setUp = function(){
// 初始代码
}
3。我要释放一些东西
扩展
JSUnitTest.prototype.tearDown = function(){
// 释放资源
}
下面我们就需要执行测试。
执行用例如下
<html>
<head>
<script tyep="text/javascript" src="jsunit.js"></script> // 应用JS文件
<script type="text/javascript">
JSUnitTest.prototype.setUp = function(){
}
// 测试ADD
JSUnitTest.prototype.testAdd = function(){
this.assertEquals("3", 1+2);
}
// 测试 MINUS
JSUnitTest.prototype.testMinus = function(){
alert(document.getElementById("hahah"
.tagName);
this.assertEquals("3", 4-1);
}
// 测试SHOW
JSUnitTest.prototype.testShow = function(){
this.assertEquals("abc", "abc"
;
}
JSUnitTest.prototype.tearDown = function(){
}
window.onload = function(){
with(new JSUnitTest()){
main();
}
}
</script>
</head>
<body>
</body>
</html>

执行完后结果都会在页面的一个表格中显示出来。
成功用例 失败用例 错误用例 这些都会统计出来
好了下面 放上JSUnitTest的源代码，那位仁兄如果有幸使用，小弟不胜感激。 如发现bug请给小弟一个mail
