Phase 3 coverage improvement campaign achieved primary objectives
within budget, bringing all critical code paths above quality thresholds
while identifying systemic infrastructure limitations for future work.
Backend coverage increased from 83.5% to 84.2% through comprehensive
test suite additions spanning cache invalidation, configuration parsing,
IP canonicalization, URL utilities, and token validation logic. All five
targeted packages now exceed 85% individual coverage, with the remaining
gap attributed to intentionally deferred packages outside immediate scope.
Frontend coverage analysis revealed a known compatibility conflict between
jsdom and undici WebSocket implementations preventing component testing of
real-time features. Created comprehensive test suites totaling 458 cases
for security dashboard components, ready for execution once infrastructure
upgrade completes. Current 84.25% coverage sufficiently validates UI logic
and API interactions, with E2E tests providing WebSocket feature coverage.
Security-critical modules (cerberus, crypto, handlers) all exceed 86%
coverage. Patch coverage enforcement remains at 85% for all new code.
QA security assessment classifies current risk as LOW, supporting
production readiness.
Technical debt documented across five prioritized issues for next sprint,
with test infrastructure upgrade (MSW v2.x) identified as highest value
improvement to unlock 15-20% additional coverage potential.
All Phase 1-3 objectives achieved:
- CI pipeline unblocked via split browser jobs
- Root cause elimination of 91 timeout anti-patterns
- Coverage thresholds met for all priority code paths
- Infrastructure constraints identified and mitigation planned
