I can successfully implement a test with React Testing Library's fireEvent method, but when I try equivalent tests with userEvent I can't get it to trigger anything. How can I fix this?

CodeSandbox

/MyInput.tsx

import { useState } from "react";

export default function MyInput() {
  const [inputTextState, setInputTextState] = useState("");
  return (
    <div>
      <label>
        My Input
        <input
          value={inputTextState}
          onChange={(event) => setInputTextState(event.target.value)}
        />
      </label>
      <p>{inputTextState}</p>
    </div>
  );
}

__tests__/MyInput.test.tsx

import { fireEvent, render } from "@testing-library/react";
import userEvent from "@testing-library/user-event";
import MyInput from "../MyInput";

const setup = () => {
  const utils = render(<MyInput />);
  const input = utils.getByLabelText("My Input") as HTMLInputElement;
  return {
    input,
    ...utils
  };
};

test("Simply input a number with fireEvent", () => {
  const { input } = setup();
  fireEvent.change(input, { target: { value: "23" } });
  expect(input.value).toBe("23");
});

test("Try userEvent", () => {
  const { input } = setup();
  userEvent.type(input, "23");
  expect(input.value).toBe("23");
});

CodePudding user response：

It was simply that I needed to add async and await:

test("Try userEvent", async () => {
  const { input } = setup();
  await userEvent.type(input, "23");
  expect(input.value).toBe("23");
});

The @testing-library/user-event at v13 didn't return a promise, but the update to v14 does. At the moment, create-react-app provides v13, so it doesn't match the latest documentation. Quite confusing for the uninitiated!
