Testing

The sheet renders through a native Modal and animates with Reanimated worklets, so it cannot run in a Jest environment as-is. The package ships a mock that covers what tests assert on:

jest.mock('react-native-actions-sheet', () =>
  require('react-native-actions-sheet/jest/mock'),
);

Rendering a sheet

<ActionSheet> renders nothing until it is shown — exactly like the real component — so show it through a ref (or SheetManager) before asserting on its content:

import {createRef} from 'react';
import {render, act} from '@testing-library/react-native';
import ActionSheet, {ActionSheetRef} from 'react-native-actions-sheet';

it('renders the sheet body once shown', () => {
  const ref = createRef<ActionSheetRef>();
  const screen = render(
    <ActionSheet ref={ref}>
      <Text>Sheet body</Text>
    </ActionSheet>,
  );

  expect(screen.queryByText('Sheet body')).toBeNull();

  act(() => ref.current?.show());

  expect(screen.getByText('Sheet body')).toBeTruthy();
});

Every method of the ref API (show, hide, snapToIndex, isOpen, …) is a jest.fn(), so you can assert on the calls:

expect(ref.current?.show).toHaveBeenCalledWith(1);

SheetManager

SheetManager.show and SheetManager.hide return promises that resolve, so awaiting them keeps working in tests:

await SheetManager.show('my-sheet');
await SheetManager.hide('my-sheet');

resetMocks

The mock keeps its behaviour under resetMocks: true (or jest.resetAllMocks()): SheetManager.show/hide still return promises, and the ref API still works. Call assertions keep working too.

// jest.config.js
module.exports = {resetMocks: true};

What the mock provides

Provided	Not provided
ActionSheet rendering its children while shown, with a spy ref API	layout, measurement, onLayout
SheetManager.show / hide promises	sheet animations, gestures, snap points
ScrollView / FlatList, re-exported from React Native	useSheetPosition values that actually change
Inert stand-ins for the hooks, so components using them render	native Modal behaviour

For behaviour the mock cannot cover — dragging, snapping, scroll handoff, keyboard handling — run the example app on a simulator or device.
