# Phase 10 Plan 03: TestHarness and Test Updates Summary

**Added setAgentQuestion convenience helper and multi-question scenario test for comprehensive questions array coverage**

## Performance

- **Duration:** 4 min
- **Started:** 2026-01-31T17:00:58Z
- **Completed:** 2026-01-31T17:04:41Z
- **Tasks:** 2
- **Files modified:** 3

## Accomplishments

- Added `setAgentQuestion` convenience method to TestHarness for single-question scenarios
- Added comprehensive multi-question scenario test with 3 questions
- Added test for `setAgentQuestion` convenience helper
- Updated TestHarness interface with proper JSDoc

## Task Commits

Each task was committed atomically:

1. **Task 1: Update TestHarness convenience methods** - `185a125` (feat)
2. **Task 2: Update all tests for questions array** - `2c41e52` (bundled with 10-02 downstream)

_Note: Task 2 changes were committed together with plan 10-02's downstream fixes due to concurrent execution_

## Files Created/Modified

- `src/test/harness.ts` - Added setAgentQuestion() convenience method
- `src/test/harness.test.ts` - Added test for setAgentQuestion helper
- `src/agent/mock-manager.test.ts` - Added multi-question scenario test

## Decisions Made

| Decision | Rationale |
|----------|-----------|
| setAgentQuestion wraps in array | Consistent with questions array schema while providing ergonomic single-question API |
| Multi-question test has 3 questions | Tests mixed scenarios: options with labels, options with descriptions, and free-form |

## Deviations from Plan

None - plan executed exactly as written.

_Note: The plan's original scope (updating all tests from singular to plural format) was already completed by plan 10-01 as a blocking deviation. This plan added the remaining convenience helper and new test coverage._

## Issues Encountered

None.

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness

- Multi-question schema complete with full test coverage
- Both convenience helpers available: setAgentQuestion (single) and setAgentQuestions (multiple)
- Ready for Phase 11 (Architect Agent)
