Description

Removes the Mosaic tests that assert where focus is restored after a list row is removed or a confirmation is cancelled. These assertions (expect(element).toHaveFocus() after a removal or cancel) have been a recurring source of flakes in the Mosaic Feature Tests CI job, including on branches that don't touch the features under test:

  • changeset-release/main (job)

  • contact-list-grid-rows (job)

  • mike/expo-verify-attach (job)

  • feat(mosaic): update banner text colors and add positive color #10169, on both attempts of this run

  • Tests whose only purpose was focus restoration are deleted (active devices, device actions, contact removal, API keys, MFA, connected accounts).

  • Tests that also cover other behavior (the mutation runs once, pending state, the primary is cleared) keep those assertions and lose only the focus checks; their names are updated to match. In the invitations and members tests, the hasInvite variation only existed for the focus check, so each is now a single test.

  • Assertions that a field receives focus when a dialog or step opens are kept, since that is not refocus.

Where focus moves after a removal is now covered by a unit test of useListRemovalFocus, the shared hook every one of these lists uses. It checks the target the hook picks (the next row, the previous row for the last one, the fallback once the list is empty, nothing after a cancel or a failed removal) without a browser or real focus timing.

📝 Walkthrough

Walkthrough

Tests across API-key, organization-profile, and user-profile flows remove assertions about focus restoration while retaining checks for dialog state, mutations, and resulting content. The active-device focus tests are removed. New hook tests cover focus targets after list removals, including fallback behavior and failed or absent removal handlers.

Restore successful-removal focus coverage.

This describe now tests focus only after cancellation. It no longer detects regressions in the successful-removal path that moves focus to the previous row and then to the current-device control. Restore an equivalent deterministic assertion without restoring the flaky timing behavior.
