单元测试的七个阶段

1 – Refuse to unit test because “you don’t have enough time”
2 – Start unit testing and immediately start blogging about unit testing and TDD and how great they are and how everyone should do it
3 – Unit test everything – make private methods internal and abuse the InternalsVisibleTo attribute. Test getters and setters or else you won’t get 100% code coverage
4 – Get fed with how brittle your unit tests are and start writing integration tests without realizing it.
5 – Discover a mocking framework and make heavy use of strict semantics
6 – Mock absolutely everything that can possibly be mocked
7 – Start writing effective unit tests
