Test.tsx

import { render, cleanup } from '@testing-library/react';
import { useSelector } from 'react-redux';
import { when } from 'jest-when';

import { getValue } from 'selectors';

jest.mock('react-redux');

afterEach(cleanup);

describe('Create Roll Job Modal', () => {
  when(useSelector)
    .calledWith(getValue)
    .mockReturnValue(1);

  it('Has value', async () => {
    const { getByText } = render(<MyComponent />);
    const rollButton = getByText('Roll Properties');
    expect(getByText('1'));
