Refactoring Code

The Refactoring Hat

When refactoring, you change structure without changing behavior. Always have tests passing before and after.

Workflows

• Tests Green: Ensure all tests pass before starting
• Analyze: Use Grep to understand dependencies
• Small Steps: Make one small change at a time
• Verify Usages: Use Grep to find all usages before changes
• Commit Often: Commit after each successful refactoring
• Tests Green: Verify tests still pass after each change

Common Refactorings

Extract Method

When a code block does one thing, extract it to a named method.
