Benefits (of using TDD to solve this problem)

• Detect special cases by using this method
• Simpler code with TDD than without using TDD
• See the patterns and after a while, reduce the patterns to something simpler
• Maybe a too simple problem, but we practice and latter if we found a more elaborate one, we will the same method and have a great benefit at the end.
• in this session, I understand how to write tests
• first time some of the people of the session write tests

Costs

• We need more preparation: find new problems to solve, prepare the environment for coding with your favorite language, ...
• long time to solve the problem (for a very simple problem)
