Starting from the enterprise operation value chain -- Test-driven development (TDD) in my eyes)

Enterprise Operation value chains are divided into three steps: discovering value, producing value, and harvesting value. I think the value chain of TDD can be divided as well. The purpose of this article is to reflect the value of TDD and try to explain the importance of TDD with an actual example.

Finally, I believe that TDD has profound internal force and can be divided into four categories:
1. Driver-Write the driver code;
2. Learning Ability-excellent teaching materials for new recruits training camp;
3. self-built and independent-the bug is minimized;
4. Control-work closely with refactoring to firmly control the development process;

Keywords: value chain, TDD, nunit, reconstruction, Singleton mode, factory Mode
