# Dependency graph
requires:
  - phase: 01-safety-hardening
    provides: validateChallengeSlug function in cmd/common.go
provides:
  - reset.go slug validation as first RunE statement (fail-fast before API call)
  - var getChallengeFn injection point for reset.go test isolation
  - cmd/reset_test.go with TestResetRunE_InvalidSlug and TestResetRunE_APIFailure
  - cmd/clean_test.go with TestCleanRunE_InvalidSlug

key-decisions:
  - "Added var getChallengeFn = getChallenge to reset.go for test injection, matching the pattern used in start.go and submit.go"
  - "validateChallengeSlug placed as first RunE statement in reset.go to align with clean.go pattern and enable no-mock slug tests"

patterns-established:
  - "Slug validation first: validateChallengeSlug as first RunE statement before any UI, API, or cluster calls"
  - "Function var injection: var xyzFn = xyz at package level enables test override without test-only files"

# Phase 2 Plan 3: Reset and Clean Command Unit Tests Summary

**reset.go aligned with clean.go slug-first validation pattern; three unit tests added covering invalid slug (no mocks) and API failure (getChallengeFn injection) paths**

## Performance

- **Duration:** 8 min
- **Started:** 2026-03-09T14:30:00Z
- **Completed:** 2026-03-09T14:38:00Z
- **Tasks:** 1
- **Files modified:** 3

## Accomplishments

- Added `validateChallengeSlug` as first statement in reset.go RunE (before `ui.Section` and `getChallenge`) — aligns with clean.go pattern
- Added `var getChallengeFn = getChallenge` to reset.go enabling test injection without touching common.go
- Created `cmd/reset_test.go` with `TestResetRunE_InvalidSlug` (no mocks) and `TestResetRunE_APIFailure` (getChallengeFn mock)
- Created `cmd/clean_test.go` with `TestCleanRunE_InvalidSlug` (no mocks — slug check fires before kube client)
- Full unit suite remains green at 45.7% coverage with -race detector

## Task Commits

1. **Task 1: Fix reset.go + write reset_test.go and clean_test.go** - `0114590` (test)

**Plan metadata:** (added after state update)

## Files Created/Modified

- `cmd/reset.go` - Added `var getChallengeFn = getChallenge` and `validateChallengeSlug` as first RunE statement
- `cmd/reset_test.go` - TestResetRunE_InvalidSlug, TestResetRunE_APIFailure
- `cmd/clean_test.go` - TestCleanRunE_InvalidSlug

## Decisions Made

- Used `getChallengeFn` as the var name (not `resetGetChallenge`) since it sits in its own file and won't collide with start.go/submit.go vars
- Only two tests for reset (invalid slug + API failure) and one for clean (invalid slug) — paths beyond API calls require a real cluster per CONTEXT.md scope

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered

None.

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness

- TST-03 satisfied: reset.go and clean.go error paths are now exercised by unit tests
- All three new tests pass with -race, full suite green
- Phase 02 command test coverage is complete for all major commands

## Self-Check: PASSED

- FOUND: cmd/reset_test.go
- FOUND: cmd/clean_test.go
- FOUND: cmd/reset.go (with validateChallengeSlug first, getChallengeFn var)
- FOUND: .planning/phases/02-command-test-coverage/02-03-SUMMARY.md
- FOUND: commit 0114590 (task commit)
- FOUND: commit db04ea0 (metadata commit)
