引言
关于单元测试的基本知识这里不再讲述，简单一句话：单元测试是用一段代码去测试另一段代码。最常用的框架是unittest，这是python的单元测试框架，而django单元测试框架test.TestCase是继承了python的unittest.TestCase。
TestCase也是对unittest.TestCase进行了进一步的封装，省去了很多重复要写的代码，比如定义一个self.client、Email Service提供了方便的邮件发送的方法。
众所周知django模式是MTV模型，其中T是模板也就是HTML文件，对于HTML来说，没有可测的代码，基本上写死，即使有，并不是重要的逻辑代码。所以在进行单元测试的时候，重点针对M和V展开，也就是models和views。
方式
单元测试进行的两种方式：
1.使用django框架自带的tests.py文件进行单元测试； 2.自定义创建test.py文件； 这两种是一样，只是运行时所执行目录不一样。
注：我这里只介绍第一种。
模型测试
