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.

The behavior I’m seeing is Jest seems to scan any function called or referenced in that file then run them independently. As I need to pass arguments to my request function, this causes some issues.

Am I doing something wrong, or is this a bug in Jest?

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();
