In `@frontend/__tests__/credential-analytics-dashboard.test.tsx`:
- Around line 5-6: Add coverage in the CredentialAnalyticsDashboard tests for a
fetch that resolves with ok set to false, and assert that the MOCK_DATA fallback
dashboard renders. Keep the existing rejected and pending fetch cases unchanged.
In `@frontend/__tests__/credential-details-modal.test.tsx`:
- Around line 56-64: Update the backdrop tests in
frontend/__tests__/credential-details-modal.test.tsx lines 56-64 and
frontend/__tests__/credential-edit-modal.test.tsx lines 66-74 to click the
modal’s absolute inset-0 backdrop and assert that the respective onClose mock is
called. Preserve the existing modal rendering setup and add coverage in both
suites.
In `@frontend/__tests__/credential-metadata-display.test.tsx`:
- Around line 121-125: Strengthen
frontend/__tests__/credential-metadata-display.test.tsx lines 121-125 by
asserting a user-visible element unique to the empty credentials state, not the
shared “Credential Metadata” heading. At lines 142-156, activate the select-all,
compare, and refresh controls and assert each control’s observable resulting
state, covering both handler wiring and UI behavior.
In `@frontend/__tests__/error-boundary.test.tsx`:
- Around line 55-65: Update the test “resets error state when Try Again is
clicked” to render a recoverable child instead of BadComponent, then assert that
the child’s normal content appears after clicking “Try Again,” verifying
handleReset actually clears the error state rather than merely preserving the
fallback.
- Around line 34-43: Extend the test for the ErrorBoundary error state to assert
that logError is called with the thrown “Test error” and the ErrorBoundary
context when BadComponent fails. Preserve the existing UI assertions while
ensuring the test would fail if componentDidCatch stops logging.
In `@frontend/__tests__/health-credential-vault.test.tsx`:
- Around line 58-64: Update the test “does not render credential list items when
empty” to query within the retrieved list and assert it contains no listitem
elements, while preserving the existing list and empty-state assertions.
In `@frontend/__tests__/notification-bell.test.tsx`:
- Around line 27-33: Update the test named “shows unread count badge when there
are unread notifications” to seed an unread notification through the existing
provider/context setup before rendering NotificationBell, then assert the unread
badge’s displayed count and the notification button’s accessible label reflect
that unread state.
In `@frontend/__tests__/notification-preferences.test.tsx`:
- Around line 77-81: Extend the push-disabled test around
NotificationPreferences to mock requestPushPermission with a granted result,
click the “Enable push notifications” control, and assert the push checkbox
replaces it; add a denied-result case that leaves the Enable button visible.
In `@frontend/__tests__/vaccination-verification-center.test.tsx`:
- Around line 46-51: Update the date formatting in VaccinationVerificationCenter
to use an explicit locale and time zone for both visible date text and
aria-label values, preventing date-only shifts and runtime-dependent formats.
Define the intended format in the component, then update the renders date labels
test to assert that exact formatting contract.

Assert the state changes that these tests describe.
The empty-array test only checks Credential Metadata, which renders in non-empty states. The control tests only check that controls mount. A regression that removes the empty-state UI or disconnects the control handlers will still pass.

Use an explicit locale and time zone for date formatting.
The component uses toLocaleDateString() for visible text and the aria-label. Date-only values can shift to the previous day in negative UTC offsets, and the format depends on the runtime locale. Define the intended date format in the component and assert that contract in the test.

Summary
Adds comprehensive unit tests for all 13 frontend components using React Testing Library and Jest. The frontend previously had only 4 test files (accessibility, animations, credential-sharing, keyboard-navigation), leaving core components with zero test coverage.
Changes
Added 10 new test files covering the following components:
