走进 .Net 单元测试Intro“不会写单元测试的程序员不是合格的程序员，不写单元测试的程序员不是优秀程序员。” —— 一只想要成为一个优秀程序员的渣逼程序猿。 那么问题来了，什么是单元测试，如何做单元测试。 单元测试定义按照维基百科上的说法，单元测试（Unit Testing）又称为模块测试,是针对程序模块（软件设计的最小单位）来进行正确性检验的测试工作。 程序单元是应用的最小可测试部件。在面向对象编程中，最小单元就是方法，包括基类、抽象类、或者派生类（子类）中的方法。 按照通俗的理解，一个单元测试判断某个特定场条件下某个特定方法的行为，如斐波那契数列算法，冒泡排序算法。
进行单元测试的好处
单元测试的原则：
VS单元测试 【MsTest】使用VS单元测试的主要类：Assert、StringAssert、CollectionAssert，具体可参照 MSDN介绍 有些时候我们需要对测试的方法用到的数据或配置进行初始化，有几个特殊的测试方法。 如果需要针对测试中的所有虚拟用户迭代仅执行一次初始化操作，请使用 TestInitializeAttribute。 初始化方法的运行顺序如下：
