Why we picked it This is the practical manual for improving code you are afraid to touch, without a rewrite. Feathers gives you techniques to get untested code under test so you can change it safely, one dependency at a time. If your instinct to rebuild really comes from fear of breaking things, this book gives you a safer path than starting over.
Working Effectively with Legacy Code
From Prentice Hall (Robert C. Martin Series) by Michael C. Feathers 456 pages
- Get code under test before you change it
- Break dependencies to make small changes safe
- You can improve scary code incrementally instead of replacing it
