Scary Large Code Surgery With Pivots

About the Book

From the Introduction:

This technique is a success story.

We were asked to make big changes, right at the heart of the oldest code in a very large codebase. It was old, crufty code, with few tests and often mysterious intent. It was clear that we could spike and refactor our hearts out for months and still not wind up with better code. This is what we did.
