Add a positive “menu opened” assertion in the pointer→keyboard flow
This test can pass even if opening breaks:
queryByText('One')is only checked after selection, so it already passes when the menu never appears. Assert open state before keyboard selection.Suggested patch
test('pointer open then keyboard navigation selects item', async() => { const user = userEvent.setup(); render(menu()); await user.click(screen.getByText('Open')); + expect(await screen.findByText('One')).toBeInTheDocument(); await user.keyboard('{ArrowDown}{ArrowDown}{Enter}'); await waitFor(() => expect(screen.queryByText('One')).not.toBeInTheDocument()); await waitFor(() => expect(screen.getByText('Open')).toHaveFocus()); });📝 Committable suggestion
