problem description

use the Jest framework to test a jsonp code, but the JsDom used by Jest seems to be unable to load the contents of the script tag, resulting in the global function of jsonp cannot be called. Therefore, the jsonp can not be done unilaterally.

jsonp is as follows:

import { jsonp } from "../src/jsonP";
test("jsonp", done => {
  jsonp("https://fake-collect.com", {a: "b"}, (err, data) => {
    expect(data).toBeTruthy();
    done();
  })
})

but each time a Error: ReqDynamic params Timeout error is thrown in the jsonp code, which represents a request timeout. Indicates that script cannot be caused by proper loading.

expected results

can run the whole process of jsonp correctly in the Jest framework, load the script` tag and the procedure that the global function is called
