Code Review: Jest 30.1.1 → 30.2.0 Update

✅ Approved - Safe to merge

Summary

This PR updates Jest from version 30.1.1 to 30.2.0, which is a minor version bump with minimal changes.

Code Quality & Best Practices

• ✅ Dependency management: Using Renovate bot for automated updates follows best practices
• ✅ Lock file only: Correctly updates only package-lock.json as this is a dependency range update
• ✅ Version range: The caret range ^30.0.0 in package.json correctly allows this minor update

Potential Issues

• ✅ No breaking changes identified - Jest 30.2.0 only includes:
  • Example repo updates for React Native testing
  • Update to jest-watch-typeahead v3 (internal dependency)
  • Minor bug fixes (30.1.2-30.1.3) for unstable_mockModule with node: prefixed modules

Performance Considerations

• ✅ Neutral impact - No performance regressions expected in this release
• The update to jest-watch-typeahead v3 may provide minor improvements in watch mode

Security Concerns

• ✅ No known vulnerabilities in Jest 30.2.0
• Regular dependency updates help maintain security posture

Test Coverage

• ⚠️ Minimal test suite: The project currently only has a basic test file (src/__tests__/basic.test.ts)
• Recommendation: As noted in CLAUDE.md, comprehensive test coverage is needed for all tool classes, ShellExecutor, and ProjectDetector

Additional Notes

Per the CLAUDE.md roadmap, the current Q1 2025 focus is on Go Support & Core Foundation. While this Jest update is important for maintenance, consider prioritizing:

1. Writing comprehensive tests for existing functionality (especially Go tools)
2. Setting up CI/CD pipeline to automatically validate these dependency updates

Recommendations

1. Merge this PR - It's a safe, minor update with no breaking changes
2. Follow-up: Create comprehensive test suite as identified in CLAUDE.md session learnings
3. Consider: Enabling Renovate automerge for patch/minor updates with passing tests once CI is set up
