import dayjs from 'dayjs';
import customParseFormat from 'dayjs/plugin/customParseFormat'
import {AvValidator} from 'availity-reactstrap-validation';
import {inputTypeOverride} from 'availity-reactstrap-validation/AvValidator/utils';

dayjs.extend(customParseFormat);

const fn = AvValidator.dateRange;
const input = {props: {type: 'text'}};
const context = {};
let date0;
let date1;
let date2;

describe('Date Range Validation', () => {
  beforeEach(() => {
    date0 = dayjs(new Date());
    date1 = dayjs(new Date());
    date2 = dayjs(new Date());
  });

  it('should not require a value', () => {
    expect(fn('', context, undefined, input)).to.be.true;
  });
