Fearlessly Refactoring Legacy Ruby

Until recently, we didn't talk much about "legacy Ruby". But today, so many companies rely on Ruby that legacy code is inevitable.

When code is hard-to-understand, we fear our changes may silently break something. This fear erodes the courage to improve code's design, making future change even harder.

If we combine proven refactoring techniques with Ruby's flexibility, we can safely add features while gradually improving our design. This talk will draw on code analysis, testing, and object-oriented design to equip attendees with a process for refactoring legacy code without fear.
