# Phase 20 Plan 02: Ch 15 Load Testing Cross-Reference Summary

**Brief Load Testing section added to Ch 15 with testing pyramid update, capability overview, and cross-reference to Ch 14**

## Performance

- **Duration:** 1 min
- **Started:** 2026-02-28T01:44:05Z
- **Completed:** 2026-02-28T01:45:06Z
- **Tasks:** 1
- **Files modified:** 1

## Accomplishments
- Added Load Testing layer to the Testing Pyramid diagram in Ch 15
- Added new Load Testing section with introduction, capability bullets, and Ch 14 cross-reference callout
- Updated Summary section with load testing in the layered approach list, key takeaways, and next steps

## Task Commits

Each task was committed atomically:

1. **Task 1: Add Load Testing section to Ch 15** - `c315e98` (feat)

**Plan metadata:** [pending final commit]

## Files Created/Modified
- `pmcp-book/src/ch15-testing.md` - Added Load Testing section, updated Testing Pyramid, updated Summary/Key Takeaways/Next Steps

## Decisions Made
- Placed Load Testing section between CI/CD Integration and Testing Best Practices -- logical position in the "advanced testing" portion of the chapter
- Added Load Testing as a top layer in the Testing Pyramid diagram rather than a footnote, since it represents the highest-level testing concern
- Used blockquote admonition style for the Ch 14 cross-reference callout, matching existing chapter conventions

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered
None.

## User Setup Required
None - no external service configuration required.

## Next Phase Readiness
- Ch 15 now cross-references Ch 14 for load testing
- Book load testing documentation phase (20) is complete pending plan 01
- Ready for course content phases (22-23)
