- Now that the legacy
TransitionComponent/TransitionPropsprops are removed, it would be good to add a regression test asserting they are not forwarded to the DOM (e.g., rendering<Accordion TransitionComponent={...} />should not set aTransitionComponentattribute on the root). This will catch accidental reintroductions of React unknown-prop warnings while still allowing apps to upgrade incrementally.
describe('slotProps.transition', () => {
it('should apply properties to the Transition component', () => {
render(
<Accordion slotProps={{ transition: { 'data-testid': 'transition-testid' } }}>
{minimalChildren}
</Accordion>,
);
expect(screen.getByTestId('transition-testid')).not.to.equal(null);
