Approval testing

Ron Jeffries recently wrote a series of articles about the Gilded Rose Kata. He tries various solutions and learns a lot along the way, (hooray!) One thing he wrote that surprised me was “I hate writing tests for existing code, and I know I’m not the only one”.

Actually, I like writing tests. It’s an interesting challenge, working out what the code does and how to test enough functionality so I can refactor safely. Perhaps another reason is because I often use Approval Testing. It seems to me I can get better tests with less test code.

In this presentation, I will show you what it looks like with some demos.
