100% code coverage… and your tests still miss bugs? Julius Mischok shows why coverage measures execution, not verification — and how #MutationTesting with #PIT proves whether tests actually fail when code changes.

How can you use code coverage and mutation testing to add tests to legacy code? At @mendercon last year, I demonstrated this powerful technique step by step on the Gilded Rose kata, which is hosted by @emilybache on her GitHub account: https://github.com/emilybache/GildedRose-Refactoring-Kata
