How to solve any problem? (Get used to fast tests & TDD)

Please tell me about the last bug you had in your code? What was the problem and how much time/money it cost to you/company to fix it?

Are tests required in your workplace? Do you write them? Do you like writing them?

• The Three Laws of TDD / Robert Martin @youtube.com
• Unit Test @martinfowler.com
• Test Driven Development @martinfowler.com

In essence you follow three simple steps repeatedly:

• Write a test for the next bit of functionality you want to add.
• Write the functional code until the test passes.
• Refactor both new and old code to make it well structured.
