Benefits of TDD
I just read a blog post about TDD and really like it, TDD for Those Who Don't Need It. It reminds me to my first impression when I start practicing TDD more than a year ago, it allows us to not have to to hold everything in our head.
By the way, that post also mentions to other TDD benefits. I want to note it down here just for a reference.

- Confidence to refactor
- Better design
- Documentation
- Regression
