Testing react-final-form using react-testing-library












1















I'm trying to use react-testing-library to test react-final-form. It works with click-events, like changing a checkbox, but I can't get it working with change-events.



Below is an example using jest as a test runner:



TestForm.js:



import React from 'react';

import { Form, Field } from 'react-final-form';



const TestForm = () => (

  <Form

    initialValues={{ testInput: 'initial value', testCheckbox: false }}

    onSubmit={() => null}

    render={({ values, initialValues }) => (

      <>

        {console.log('VALUES', values)}

        <label>

          Checkbox label

          <Field name="testCheckbox" component="input" type="checkbox"/>

        </label>

        <Field name="testInput" component="input" placeholder="placeholder" />

        {values.testCheckbox !== initialValues.testCheckbox && <div>Checkbox has changed</div>}

        {values.testInput !== initialValues.testInput && <div>Input has changed</div>}

      </>

    )}

  />

);



export default TestForm;


test.js:



import React from 'react';

import { cleanup, fireEvent, render, waitForElement } from 'react-testing-library';



import TestForm from './TestForm';



afterEach(cleanup);



describe('TestForm', () => {

  it('Change checkbox', async () => {

    const { getByLabelText, getByText } = render(<TestForm />);

    const checkboxNode = getByLabelText('Checkbox label');

    fireEvent.click(checkboxNode);

    await waitForElement(() => getByText('Checkbox has changed'));

  });

  it('Change input', async () => {

    const { getByPlaceholderText, getByText } = render(<TestForm />);

    const inputNode = getByPlaceholderText('placeholder');

    fireEvent.change(inputNode, { target: { value: 'new value' } });

    await waitForElement(() => getByText('Input has changed'));

  });

});


I run this using npx jest test.js and the first test passes but not the second.



The crucial part that doesn't seem to work is



fireEvent.change(inputNode, { target: { value: 'new value' } });


Any suggestions?
