facilis-testing

Testing helpers for Facilis formats and adapters.

Usage

import { setupInput, textState } from 'facilis-testing';
import { creditCard } from 'facilis-formats';

const input = setupInput(creditCard());

expect(input.append('4111', '1')).toEqual(textState('4111 1', 6));

setupInput() creates a stateless test input around one Facilis format. Each method call derives its own text snapshots from the arguments passed to that call.

textState() creates the { value, selectionStart, selectionEnd } object used by Facilis format results.
