react-testing: userEvent.click does not work

Question

I'm trying to use userEvent for testing UI interaction. However, it does not seem to work properly. I used this document as reference. Is there some necessary setup in order for it to work?

Here's the test code:

  test('A', () => {
    //setup
    const user = userEvent.setup();

    const sensing = jest.fn();
    const subject = (<button onClick={sensing}>testButton</button>);

    render(subject);

    // run
    user.click(screen.getByText('testButton'));

    // check
    expect(sensing).toBeCalledTimes(1);
  });

Using fireEvent.click instead of user.click does work.

Part of package.json

"react": "^18.1.0",
"react-dom": "^18.1.0",
"@storybook/react": "^6.4.22",
"@storybook/testing-library": "^0.0.9",
"@testing-library/dom": "^8.13.0",
"@testing-library/jest-dom": "^5.16.4",
"@testing-library/react": "^13.2.0",
"@testing-library/react-hooks": "^8.0.0",
"@testing-library/user-event": "^14.2.0",

UserEvent needs await. So you want to write this:

  test('A', async () => {
    //setup
    const user = userEvent.setup();

    const sensing = jest.fn();
    const subject = (<button onClick={sensing}>testButton</button>);

    render(subject);

    // run
    await user.click(screen.getByText('testButton'));

    // check
    expect(sensing).toBeCalledTimes(1);
  });
