2026-03-28 Q-004 Coverage Remediation Pass 17

Scope

• Continue strict Q-004 closure work after Pass 16.
• Fully close the remaining dashboard hotspot in:
  • frontend/admin/src/pages/admin/DashboardPage/DashboardPage.tsx
• Re-verify closure through targeted dashboard tests and full frontend validation.

Changes

Frontend

• Added dedicated dashboard coverage in:
  • frontend/admin/src/pages/admin/DashboardPage/DashboardPage.test.tsx
• Newly covered behavior includes:
  • initial loading state
  • successful stats rendering
  • retriable error state
  • retry recovery path
  • empty payload fallback when the stats payload is missing
• Test setup intentionally isolates shell dependencies and service responses so the page state machine is exercised deterministically.

Backend

• No backend code changes were required in this pass.

Verified Commands

cd D:\project\frontend\admin
npm.cmd run test:run -- src/pages/admin/DashboardPage/DashboardPage.test.tsx
npm.cmd run lint
npm.cmd run build
npm.cmd run test:coverage

Results

Frontend coverage

• Overall:
  • statements 91.66%
  • branches 78.26%
  • functions 87.86%
  • lines 91.82%
• Target area:
  • src/pages/admin/DashboardPage/DashboardPage.tsx: statements 100%, branches 100%, functions 100%, lines 100%

Validation outcomes

• Full frontend coverage run now completes with:
  • 48 passing test files
  • 218 passing tests
• The required sequential frontend validation path passed:
  • test:run -- src/pages/admin/DashboardPage/DashboardPage.test.tsx
  • lint
  • build
  • test:coverage

Validation Notes

• The successful frontend coverage run still emits one post-summary jsdom AggregateError network-noise line.
  • It does not fail the command.
  • It remains a real validation-hygiene issue and cannot be hidden.

Real Conclusion

• src/pages/admin/DashboardPage/DashboardPage.tsx is no longer an open Q-004 gap.
• Q-004 still cannot be honestly declared closed.
• After this pass, the main remaining frontend gaps narrow further to:
  • src/components/feedback/PageState/PageState.tsx
  • additional lower-coverage shared/admin surfaces outside this pass
  • the post-summary jsdom AggregateError coverage-noise hygiene issue
