How do i write a jest testcase for the following function

Am trying to write JEST testcase for the following function. Could you please someone help?

const fetch = require('node-fetch');    async function fetchFun(endPointurl, options) {    try {      const response = await fetch(endPointurl, options);      if (!response.ok) {        throw response.json();      }      const contentType = response.headers.get('Content-Type');      if (contentType.includes('text/html')) {        return await response.text();      }      return await response.json();    } catch (error) {      throw error;    }  }  export default fetchFun;
