FAQs and criticism
TDD is one of the most controversial topics in modern software development. You will find some developers swearing by it and others claiming it is useless.
I will try to objectively answer the questions and show you both views where relevant.
Why do I need to do TDD? Can’t I just do unit testing?
As you’ve gathered from the start of the chapter, TDD is a style of writing unit tests. So, yes, you can write unit tests without following the TDD style. In the next chapter, you will find the first guideline from the FIRSTHAND guidelines that will focus on the benefits of following the TDD style.
I found that some teams are reluctant to do TDD for various reasons. My recommendation is not to abandon unit tests in case your team is not inclined to follow TDD. Maybe if you start with unit testing, then the next evolution would be TDD. This would slow down the rate of change for some teams.
Did I say this before? Don’t abandon unit testing...
