Handoff: ContentService Refactoring Phase 0 - Test Infrastructure

Task(s)

Executing Phase 0 of ContentService refactoring using Subagent-Driven Development workflow. Phase 0 creates test and benchmark infrastructure to establish baseline metrics before refactoring begins.

Implementation Plan: docs/plans/2025-12-20-contentservice-refactor-phase0-implementation.md

Critical References

1. Implementation Plan: docs/plans/2025-12-20-contentservice-refactor-phase0-implementation.md - Contains exact test code to add for each task
2. Subagent-Driven Development Skill: ~/.claude/plugins/cache/superpowers-marketplace/superpowers/4.0.0/skills/subagent-driven-development/ - Workflow being followed

Recent changes

• tests/Umbraco.Tests.Integration/Umbraco.Infrastructure/Services/ContentServiceRefactoringTests.cs - Added 5 tests (2 notification ordering, 3 sort operation)
• Commits made: 09cc4b022e (Task 2 initial), amended with fixes, 86b0d3d803 (Task 3)

Learnings

1. Subagent-Driven Development Workflow:

   • Dispatch implementer subagent with FULL task text from plan (don't make subagent read files)
   • Dispatch spec compliance reviewer to verify implementation matches spec exactly
   • If issues found, dispatch fix subagent, then re-review
   • Dispatch code quality reviewer only AFTER spec compliance passes
   • Mark task complete only when both reviews approve

2. Test Patterns in Umbraco:

   • Base class UmbracoIntegrationTestWithContent provides Textpage, Subpage, Subpage2, Subpage3
   • Textpage is NOT published by default - tests may need to publish parent before creating child content
   • Use ContentBuilder.CreateSimpleContent() to create fresh test content
   • Use RefactoringTestNotificationHandler.Reset() before testing notifications

3. Spec Compliance:

   • First implementation of Task 2 deviated from spec (used fixtures instead of creating content)
   • Reviewer caught this and fix was applied successfully
   • Lesson: Spec reviewer is critical for catching deviations

Artifacts

• tests/Umbraco.Tests.Integration/Testing/ContentServiceBenchmarkBase.cs - Benchmark base class (committed in Task 0)
• tests/Umbraco.Tests.Integration/Umbraco.Infrastructure/Services/ContentServiceRefactoringTests.cs - Integration tests (Tasks 1-3)
• docs/plans/2025-12-20-contentservice-refactor-phase0-implementation.md - Full implementation plan with code

Action Items & Next Steps

Resume using subagent-driven development workflow:

1. Task 4: Add DeleteOfType tests (Tests 6-8)

   • Dispatch implementer subagent with Task 4 from plan (lines 684-863)
   • After implementation, dispatch spec reviewer
   • After spec approval, dispatch code quality reviewer
   • Mark complete when approved

2. Task 5: Add permission tests (Tests 9-12)

   • Same workflow as Task 4
   • Plan lines 866-1059

3. Task 6: Add transaction boundary tests (Tests 13-15)

   • Same workflow
   • Plan lines 1063-1228

4. Task 7: Create ContentServiceRefactoringBenchmarks.cs

   • Large file (33 benchmarks) - may take longer
   • Plan lines 1231-2386

5. Task 8: Create ContentServiceBaseTests.cs

   • Unit tests (skeleton with tracking test)
   • Plan lines 2389-2657

6. Tasks 9-11: Verification and baseline capture

   • Run all tests, capture benchmarks, create git tag

Other Notes

• The implementation plan has gone through 3 critical reviews (v1.1, v1.2, v1.3) - all feedback has been incorporated
• Key revision notes are at the top of the plan document
• Benchmark data sizes are standardized to 10/100/1000 pattern (v1.2)
• Warmup logic was corrected for both destructive and non-destructive benchmarks
• ContentServiceBase doesn't exist yet - Task 8 creates tracking test that fails when it's created in Phase 1
