利用VisualStudio白盒测试入门

现在越来越多的软件开发使用白盒测试了，C++有CppUnit，.Net有NUnit， 在VisualStudio中也给我们提供了一套测试框架，但是该测试框架似乎只有在VS某几个版本才有。

    那么VisualStudio有哪些版本呢？以VisualStudio2005来看，他有些什么版本呢？各个版本有些什么区别呢？

    下表是从该网页中拷贝出来的。即Visual Studio 2005产品线一览图。

  简单来说，我们可以归纳一下：
  Express---试用版
  Pro---全称是Visual Studio 2005 Professional Edition，是适合小规模使用的版本，授权8-10个人左右。
  Std---全称是Visual Studio Standard Edition，也是授权版本，比Pro多一些；
  VSTO---Visual Studio 2005 Tools for the Microsoft Office System，对office系列产品进行开发；
  VSTS---Visual Studio 2005 Team System，也是针对软件开发的各个层次最全面的一个版本
   可以看到，这几个版本中，只有VSTS有Unit Test的功能。所以要想利用VisualStudio来做白盒测试，必须安装VSTS，其他版本都没有。

    安装完VSTS后，开始写白盒测试代码吧。如图一步一步做吧：

    1.新建测试项目

    2.在生成的UnitTest1.cs文件中修改代码，如图所示：

    这样我们写了2个测试方法TestMethod1(),TestMethod2(); 分别让其通过和不通过。

    3.在实际的项目中，测试方法（Test Method）会非常多，为了方便管理，会建一些测试列表（Test List），如图所示：

    4.忘了说了，Test Manager这个工作区是怎么显示出来的了。

先在菜单 View – Toolbars - Test Tools 中选中，让其显示测试工具条，然后在测试工具条上点击Test Manager按钮，请看下图。

    然后呢，如上图所示，先在Test Manager中选中要运行的Test Method，然后点击用红框标出的按钮，就可以运行选中的Test Method了。
    运行完之后，打开Test Result面板，就能看到运行的结果了，可以看到，我们写的Test Method，一个Passed了，一个Failed了。
    呵呵，白盒测试入门就是这么简单。
