If it’s not tested, it doesn’t work Or at least it will soon stop working. ## WHAT'S 4/p5_1.jpg) BUT WHEN I DO, DO IT IN PRODUCTION Software development done right is basically testing and debugging. ## GOOD TESTS ARE • Independent • Repeatable Fast ## DIFFERENT TESTS — ALL ARE generally shallow / easy-to-fix. Tests run fast – tight feedback loop. But... Assumptions! ## UNIT TESTING FRAMEWORKS Google Gest Catch2 Boost.Test • CppUTest • doctest ![Image](/uploads/documents/
