  • internal/util: 100.0%
  • internal/version: 100.0%

API-Friendly Preset Tests Verified:

• ✅ TestGetPresets - Verifies all 4 presets returned in correct order
• ✅ TestGetPresets_IncludesAPIFriendly - Dedicated test for API-Friendly preset specifics
• ✅ TestEnsurePresetsExist_Creates - Verifies presets are created in database

---

1.2 Frontend Coverage Tests ✅

Command: scripts/frontend-test-coverage.sh (VS Code Task: "Test: Frontend with Coverage") Status: ✅ PASS Coverage: 87.29% (minimum required: 85%)

Test Results:

• Test Files: All passed
• Total Tests: All passing
• Key Coverage Areas:
  • src/pages/SecurityHeaders.tsx: 63.93%
  • src/components/ProxyHostForm.tsx: 79.62%
  • src/hooks/useSecurityHeaders.ts: 97.14%

---

1.3 Type Safety Check ✅

Command: cd frontend && npm run type-check (VS Code Task: "Lint: TypeScript Check") Status: ✅ PASS TypeScript Errors: 0

---

2. Pre-commit Hooks ⚠️

Command: pre-commit run --all-files Status: ⚠️ PASS WITH NOTES

Hooks Results:

• ✅ fix end of files
• ✅ trim trailing whitespace
• ✅ check yaml
• ✅ check for added large files
• ✅ dockerfile validation
• ✅ Go Vet
• ⚠️ Check .version matches latest Git tag - Expected Failure (version 0.11.2 vs tag v0.14.1)
• ✅ Prevent large files that are not tracked by LFS
• ✅ Prevent committing CodeQL DB artifacts
• ✅ Prevent committing data/backups files
• ✅ Frontend TypeScript Check
• ✅ Frontend Lint (Fix)

Note: Version mismatch is a pre-existing condition unrelated to current changes.

---

3. Code Quality ✅

3.1 Backend Compilation

Command: cd backend && go build ./... Status: ✅ PASS - Compiles without errors

3.2 Console.log Audit

Status: ⚠️ EXISTING (Pre-existing, non-critical)

Existing console.log statements (diagnostic/debugging for WebSocket connections):

• frontend/src/components/LiveLogViewer.tsx:186 - WebSocket connected status
• frontend/src/components/LiveLogViewer.tsx:198 - WebSocket disconnected status
• frontend/src/context/AuthContext.tsx:73 - Auto-logout notification
• frontend/src/api/logs.ts:137-225 - WebSocket diagnostic logging (7 occurrences)

Assessment: These are intentional diagnostic logs for WebSocket connection state, useful for debugging connection issues. Not blocking.

3.3 Commented-out Code

Status: ✅ PASS - No TODO/FIXME/HACK/XXX comments in frontend code

---

4. Security Scans ✅

4.1 Go Vulnerability Check

Command: cd backend && go run golang.org/x/vuln/cmd/govulncheck@latest ./... (VS Code Task: "Security: Go Vulnerability Check") Status: ✅ PASS Result: No vulnerabilities found

---

8. Issues Found

Issue #1: Pre-existing Console.log Statements

Severity: 🟡 LOW (Pre-existing, diagnostic) Location: frontend/src/api/logs.ts, frontend/src/components/LiveLogViewer.tsx, frontend/src/context/AuthContext.tsx Description: 9 console.log statements for WebSocket connection diagnostics Impact: None - diagnostic logging for debugging purposes Recommendation: Consider converting to conditional debug logging or removing in future cleanup task

Issue #2: Version Tag Mismatch

Severity: 🟡 LOW (Pre-existing) Location: .version file Description: .version (0.11.2) doesn't match latest Git tag (v0.14.1) Impact: Pre-commit hook warning only Recommendation: Update version file or create new tag as part of release process

---

All critical requirements met:

• Coverage thresholds exceeded (Backend: 85.6%, Frontend: 87.29%)
• All tests passing
• Zero TypeScript errors
• Zero security vulnerabilities
• API-Friendly preset correctly implemented with score 70 and CORP=cross-origin
