本文分享了作者在阅读《Test-Driven Development by Example》一书后，进行TDD实践的感受与体会。通过一个简单的money例子，作者对TDD中的Red-Green-Refactor循环有了更深入的理解，并对书中提出的依赖问题和重构方法感到启发。

下午看了这本书,虽然只看了一半,但是自己进行了一点TDD的实践,有点感觉.
[quote]Test-Driven Development by Example
Quickly add a test
Run all tests and see the new fail.
Make a little change.
Run all tests and see them all succeed.
Refactor to remove duplication.

Red-->Green-->Refactor

The problem is the dependency between code and test.
Dependency is problem, and duplication is symptom.

Write a test.
Make it run.
Make it right.

The goal is clean code that works.

Fake it
Use obvious implementation.

Value Object:
All operations return a new object.
Implement equal().

TDD的感觉还不错.虽然在简单的money例子中体现的不是很确切.关于money例子的refactor的方法很有启发.
