Suture is a Ruby gem that makes it safer to refactor or fully reimplement poorly-understood legacy code. It supports the whole refactor lifecycle by recording calls to a 'seam' and verifying that new implementations match the old behavior in development, staging, and production.
Use cases
- safely refactor legacy ruby code
- reimplement a code path without breaking behavior
- record and replay production calls to verify a rewrite
- characterization testing for untested code
- create seams around code I don't understand
- verify new implementation matches old one in production
When to choose
- you need to change or rewrite critical Ruby code with no tests
- you want recorded real-world inputs to validate a reimplementation
- you're doing incremental strangler-style refactors in Ruby
When to avoid
- your codebase is well-tested and easy to change directly
- you work outside Ruby
- you need active development or new features
