A few days ago, a developer at work said something that made me cringe, “Every day we write more legacy code”. My first instinct was to reinstate our corporal punishment policy.
Then he said something quite amazing that I didn’t expect, “Any code we are afraid to change, because it isn’t thoroughly tested, is legacy code.” I cried. Literally.
Figuratively.
I know he read this in Working Effectively with Legacy Code, but to really see him get the importance of testing is awesome.
After hearing a few developers say this book is in their top five, I need to get on the ball and read it myself.
