# 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`
|
||
|
|

|
## 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
