After TDD cycle, look for:
|
|
|
|
- **Duplication** → Extract function/class
|
|
- **Long methods** → Break into private helpers (keep tests on public interface)
|
|
- **Shallow modules** → Combine or deepen
|
|
- **Feature envy** → Move logic to where data lives
|
|
- **Primitive obsession** → Introduce value objects
|
|
- **Existing code** the new code reveals as problematic
