Javascript – How to Call a Function Needed for a File listed under setupFiles in Jest?

I’m using setupFiles in Jest to call an authentication flow for a new test framework. As part of that effort I’ve started abstracting common request types to a separate file, then referencing them in my auth setup file.

But for some reason the function is called without passing any arguments.

jest.config.cjs

setupFiles: ['./tests/lib/auth.cjs'],

auth.cjs

const request = require('./requests.cjs');
const microsoftLoginUrl = 'https://login.microsoftonline.com/';

async function getAuthCookie() {
    // Login
    const loginResponse = await request.post(
      `${microsoftLoginUrl}xxxxx/login`,
      {
        login: 'xxxx',
        passwd: 'xxxxx',
        canary: canary,
        ctx: ctx,
        hpgRequestId: sessionId,
        flowToken: sft,
      },
      {
        'Content-Type': 'application/x-www-form-urlencoded',
      }
    );

requests.cjs

async function post(url, body, headers) {
  body.headers = headers;
  const postConstants = { method: 'POST', body: new URLSearchParams({ body }) };
  return await fetch(url, postConstants);
}

module.exports = post();

    Not exactly sure why, but changing my export and import fixes it. So:

    module.exports = { post };

    const { post } = require('./requests.cjs');

    I would prefer not to use brackets with requests only having a single function, but I do plan to add other request types, so I guess it's ok.

    module.exports = post() exports the result of post, not the function itself. In case this is not the intention, it should be

    module.exports = post;
