如何创建一个简单的示例控制台应用程序，用于为测试驱动开发开发单独的类？

StackOverflow https://stackoverflow.com/questions/810465

题

我打算创建一个简单易于调试的控制台应用程序，它将成为C＃中测试驱动开发单个类的模板（或起点）。目的是有一个简单的文件夹，这个控制台应用程序将驻留在该文件夹中，只需复制粘贴文件夹打开新项目并开始编写新类。一旦所有功能都经过测试（最好是测试应该在同一个文件中（或者至少是命名空间），这个类将被允许进入更大的项目。我使用的是NUnit和log4net。如果你这样做的话“小型测试驱动单元构建”方法如何实现它。请发布一些代码或解释。如果您不使用，请提供解释原因？ 这是代码（配置数据也粘贴为注释......）

其他提示

我真的没有看到在现有项目中包含新类的好处，包括现有测试项目中的新测试类，以及在那里运行测试。

为什么要推出一款控制台应用？您是否真的需要从控制台应用程序而不是现有的测试运行程序中运行测试？ （不要误解我的意思，我是控制台应用程序的忠实粉丝 - 我只是不知道它们是如何适应的。）
