出于某种原因，我的测试在使用这样的 ref 时没有通过：

import React, { useRef } from "react";
import { waitForElement, render } from "@testing-library/react";

const MyComponent = props => {
  const elementRef = useRef(null);
  return (
    <div>
      <div ref={elementRef} />
      {elementRef.current && <div data-testid="test-div" />}
    </div>
  );
};

describe("MyComponent", () => {
  it("test-div should exist when the ref is set", async done => {
    const { getByTestId } = render(<MyComponent />);
    await waitForElement(() => getByTestId("test-div"));
  });
});

知道为什么这不起作用吗？
