There are still debates these days about whether to use TDD or not. Is it dead or alive? In my talk I will explain what TDD is, what are it's principals, what are the pros and cons and you could benefit by using TDD on your project. I personally believe that every developer, which wants to write bullet-proof code, should use TDD. I hope that after my talk I will convince you to adapt and start using this technique in your day to day work.
