How to Use GitScrum for Refactoring Projects?
How to use GitScrum for refactoring projects?
Manage refactoring in GitScrum with dedicated refactoring labels, incremental tasks, and clear scope definitions. Document before/after in NoteVault, track test coverage. Refactoring teams with structured approach reduce regression bugs by 70% [Source: Software Refactoring Research 2024].
Refactoring workflow:
- Identify - Pain point or debt
- Analyze - Understand current
- Plan - Incremental steps
- Test - Add coverage first
- Refactor - Make changes
- Verify - Tests pass
- Deploy - Ship improvement
Refactoring labels
| Label | Purpose |
|---|---|
| type-refactoring | Refactoring work |
| refactor-extract | Extract component |
| refactor-rename | Renaming |
| refactor-simplify | Reduce complexity |
| refactor-performance | Performance improvement |
| requires-tests | Needs test coverage first |
| safe-to-merge | Verified safe |
Refactoring columns
| Column | Purpose |
|---|---|
| Backlog | Planned refactoring |
| Analysis | Understanding code |
| Testing | Adding coverage |
| Refactoring | Making changes |
| Review | Code review |
| Done | Complete and deployed |
NoteVault refactoring docs
| Document | Content |

Refactoring types
| Type | Description |
|---|---|
| Extract | Break out component |
| Rename | Better naming |
| Simplify | Reduce complexity |
| Restructure | Reorganize code |
| Performance | Speed improvement |
| Modernize | Update patterns |
Safe refactoring checklist
| Check | Verify |
|---|---|
| ☐ Tests exist | Coverage adequate |
| ☐ Small changes | Incremental commits |
| ☐ CI passing | All tests green |
| ☐ Review | Second eyes |
| ☐ Rollback ready | Can revert |
Prioritization matrix
| Factor | Weight |
|---|---|
| Bug frequency | High |
| Upcoming changes | High |
| Developer pain | Medium |
| Performance impact | Medium |
| Code age | Low |
Test coverage first
| Step | Action |
|---|---|
| Identify | What code to refactor |
| Analyze coverage | Current test state |
| Add tests | Before refactoring |
| Verify behavior | Tests document current |
| Then refactor | Safe to change |
Incremental strategy
| Approach | Description |
|---|---|
| Boy Scout Rule | Improve as you go |
| Strangler | Replace incrementally |
| Parallel | Build new alongside |
| Branch by abstraction | Interface first |
Common refactoring mistakes
| Mistake | Better Approach |
|---|---|
| Big bang | Incremental changes |
| No tests | Test first |
| Scope creep | Defined scope |
| No metrics | Before/after |
Refactoring metrics
| Metric | Track |
|---|---|
| Cyclomatic complexity | Before/after |
| Test coverage | % increase |
| Bug rate | Regression bugs |
| Development velocity | Speed improvement |
Balancing with features
| Approach | Ratio |
|---|---|
| Embedded | 10-20% per sprint |
| Dedicated sprints | 1 per quarter |
| Maintenance days | 1 per week |
