Pull request overview

Adds Vitest/@testing-library unit test coverage across additional libs/ui components to better lock in expected DOM structure, SLDS class generation, callbacks, and basic a11y roles/attributes.

Changes:

Added new test suites for Section, Toolbar*, Grid/GridCol, Spinner, Pill, and Breadcrumbs.
Added new test suites for Checkbox, ProgressStepIndicator*, List/ReadonlyList, and Tree (including imperative ref behaviors).
Expanded coverage around ARIA attributes/roles and component callback wiring.

libs/ui/src/lib/list/__tests__/List.spec.tsx

+  test('keyboard ArrowDown moves focus to next item', () => {
+    const onSelected = vi.fn();
+    render(
+      <List
+        items={items}
+        isActive={(item) => item.id === 'item-1'}
+        getContent={getContent}
+        onSelected={onSelected}
+      />,
+    );
+    const listbox = screen.getByRole('listbox');
+    fireEvent.keyDown(listbox, { key: 'ArrowDown', code: 'ArrowDown' });
+    // No error means keyboard handler ran successfully
+  });


The keyboard navigation tests here don’t assert any observable outcome (they pass even if the key handler is removed). Since List moves focus via the internal focusedItem state, consider asserting that focus actually changes (e.g., document.activeElement becomes the expected option after ArrowDown).

libs/ui/src/lib/list/__tests__/List.spec.tsx

+    );
+    const listbox = screen.getByRole('listbox');
+    fireEvent.keyDown(listbox, { key: 'Home', code: 'Home' });
+    // No error means keyboard handler ran successfully


This Home-key test currently only fires a keyDown event without asserting behavior. To ensure keyboard support doesn’t regress, assert the expected focused element (e.g., after pressing Home, the first option receives focus).

Suggested change

// No error means keyboard handler ran successfully

const options = screen.getAllByRole('option');

const firstOption = options[0];

expect(document.activeElement).toBe(firstOption);

libs/ui/src/lib/section/__tests__/Section.spec.tsx

+// Note: Section.tsx sets aria-expanded={!expanded} on the toggle button,
+// which is inverted from the ARIA spec convention. These tests reflect the
+// actual component behavior.


These tests document that Section sets aria-expanded={!expanded}, which is inverted from the ARIA expected meaning (aria-expanded should be true when the controlled region is expanded). Adding tests that lock in this inverted behavior will make an accessibility fix harder later; please consider fixing Section.tsx to use the correct aria-expanded={expanded} and updating these expectations accordingly (keeping aria-hidden aligned).

Addressed in commit 3c1f581:

CI failure (Popover unhandled rejection): Added vi.mock('@jetstream/ui/app-state', ...) to the Popover test. Popover imports Tooltip from the ui barrel index, which transitively loads NotSeeingRecentMetadataPopover and UserFeedbackWidget — both of which import @jetstream/ui/app-state. That module calls fetchUserProfile() at init time, which makes an HTTP request that fails in the test environment. Vitest's mock hoisting ensures the mock is applied before any imports run.

Section aria-expanded bug: Fixed Section.tsx to use aria-expanded={expanded} (was incorrectly inverted as {!expanded}). Updated all Section test expectations to match correct ARIA semantics (true = open, false = closed).

List keyboard navigation tests: Replaced the no-op comment tests with real document.activeElement assertions — ArrowDown from item-1 focuses options[1], Home focuses options[0].
