How to test utility function with Jest + React Testing Library

How can I test this function which creates HTML image element according to url using react testing library

export const createImage = (url: string): Promise<HTMLImageElement> => {
 return new Promise((resolve, reject) => {
  const image = new Image();
  image.addEventListener('load', () => resolve(image));
  image.addEventListener('error', error => reject(error));
  image.setAttribute('crossOrigin', 'anonymous');
  image.src = url;
  });
};
