Pull request overview

Adds Vitest/RTL coverage for four previously untested dialog components to address issue #1626, focusing on basic rendering, a11y roles, and primary close/interaction paths.

Changes:

Adds new test suites for DeleteTracksConfirmDialog, BounceInPlaceDialog, KeyboardShortcutsDialog, and CommandPalette.
Exercises modal open/close behavior via useUIStore state and basic UI rendering assertions.
Introduces mocks for BounceInPlaceDialog dependencies (action API, toast, logger).

The test suite mutates useUIStore state but never fully resets it, which can leak modal flags (e.g. showShortcutEditorDialog) into other tests/files. Consider resetting the store in beforeEach using useUIStore.setState(useUIStore.getInitialState(), true) (pattern used in src/store/__tests__/uiStore.test.ts).

Suggested change

beforeEach(() => {

beforeEach(() => {

useUIStore.setState(useUIStore.getInitialState(), true);

+  beforeEach(() => {
+    useUIStore.setState({
+      showCommandPalette: true,
+      commandPaletteQuery: '',
+    });
+  });


This suite sets a couple of useUIStore keys in beforeEach but does not fully reset the store. Because uiStore is shared across tests, persistent fields like recentCommandIds, modal flags, or selection state can leak and make these tests order-dependent. Prefer fully resetting with useUIStore.setState(useUIStore.getInitialState(), true) in beforeEach and then setting the minimal required keys.

+    const listbox = screen.queryByRole('listbox');
+    // Listbox appears when there are results
+    if (listbox) {
+      expect(listbox).toBeInTheDocument();
+    }


The "renders search results" test is effectively non-asserting: if the listbox is missing, the test still passes due to the if (listbox) guard. Since CommandPalette renders a listbox when there are results, this should use a failing assertion (e.g., getByRole('listbox')) after setting up state that guarantees at least one result, or remove/replace the test.

Suggested change

const listbox = screen.queryByRole('listbox');

// Listbox appears when there are results

if (listbox) {

expect(listbox).toBeInTheDocument();

}

const listbox = screen.getByRole('listbox');

expect(listbox).toBeInTheDocument();

+      pendingDeleteTrackIds: [trackIds[0]],
+      confirmDeleteTracks: confirmSpy,
+    });
+    render(<DeleteTracksConfirmDialog />);


These tests replace useUIStore action functions (confirmDeleteTracks / cancelDeleteTracks) with spies via setState but never restore the original implementations. Because useUIStore is global, this can leak into later tests in this file or other files. Prefer vi.spyOn(useUIStore.getState(), 'confirmDeleteTracks') / vi.spyOn(..., 'cancelDeleteTracks') (or reset the store with useUIStore.setState(useUIStore.getInitialState(), true) in beforeEach/afterEach).

+      pendingDeleteTrackIds: [trackIds[0]],
+      cancelDeleteTracks: cancelSpy,
+    });
+    render(<DeleteTracksConfirmDialog />);


Same store-leak issue here: cancelDeleteTracks is overridden via setState and not restored. If you keep this approach, ensure the UI store is fully reset between tests (see src/store/__tests__/uiStore.test.ts for the getInitialState() reset pattern).

+    // Close button is the × character
+    const closeBtn = screen.getAllByRole('button').find(
+      (btn) => btn.textContent === '×',
+    )!;


The close-button test finds a button by its textContent === '×', which is brittle and can break with minor UI/typography changes. Since the component button currently has no accessible label, consider adding an aria-label in the dialog component and updating the test to query by label (more robust and improves a11y).

Suggested change

// Close button is the × character

const closeBtn = screen.getAllByRole('button').find(

(btn) => btn.textContent === '×',

)!;

const closeBtn = screen.getByRole('button', { name: /close/i });

+
+describe('BounceInPlaceDialog', () => {
+  beforeEach(() => {


The suite sets up useProjectStore / useUIStore state in beforeEach but does not fully reset either store. Since these are global Zustand stores, leftover state from other tests can leak in and cause flakiness. Consider resetting both stores to getInitialState() in beforeEach and then calling setupBounceDialog().

Suggested change

beforeEach(() => {

beforeEach(() => {

useProjectStore.setState(useProjectStore.getInitialState(), true);

useUIStore.setState(useUIStore.getInitialState(), true);

+  it('has Cancel and Bounce Track buttons', () => {
+    render(<BounceInPlaceDialog />);
+    expect(screen.getByText('Cancel')).toBeInTheDocument();
+    expect(screen.getByText('Bounce Track')).toBeInTheDocument();
+  });


Per the PR/issue description, Bounce In Place coverage should include the actual bounce action. Currently no test clicks "Bounce Track" or asserts projectActionApi.bounceInPlace is called and that the dialog closes on { ok: true }. Adding an async test for that behavior would better match the stated acceptance criteria.

- All 4 test files: reset stores with getInitialState() in beforeEach to prevent state leaking between tests - CommandPalette: remove unused vi import, make listbox assertion unconditional (getByRole instead of queryByRole with guard) - KeyboardShortcutsDialog: remove unused vi import - DeleteTracksConfirmDialog: use vi.spyOn instead of overriding store actions via setState to prevent leaked mocks - BounceInPlaceDialog: add test for actual bounce action (clicks Bounce Track button, asserts projectActionApi.bounceInPlace called) https://claude.ai/code/session_01AAbmUU34sN8t5XRPsvuyzh
