Require not behaving as expected

I'm using the proxyquire library, which mocks packages on import.

I'm creating my own proxyquire function, which stubs a variety of packages I use regularly and want to stub regularly (meteor packages, which have a special import syntax):

// myProxyquire.js
import proxyquire from 'proxyquire';

const importsToStub = {
  'meteor/meteor': { Meteor: { defer: () => {} } },
};

const myProxyquire = filePath => proxyquire(filePath, importsToStub);

export default myProxyquire;

Now I want to write a test of a file which uses one of these packages:

// src/foo.js
import { Meteor } from 'meteor/meteor'; // This import should be stubbed

export const foo = () => {
  Meteor.defer(() => console.log('hi')); // This call should be stubbed
  return 'bar';
};

And finally I test it like this:

// src/foo.test.js
import myProxyquire from '../myProxyquire';

// This should be looking in the `src` folder
const { foo } = myProxyquire('./foo'); // error: ENOENT: no such file

describe('foo', () => {
  it("should return 'bar'", () => {
    expect(foo()).to.equal('bar');
  });
});

Note that my last 2 files are nested inside a subfolder src. So when I try to run this test, I get an error saying that the module ./foo couldn't be found, as it is being looked for in the "root" directory, where the myProxyquire.js file is, not the src directory as expected.

You might be able to work around that (expected) behaviour by using a module like caller-path to determine from which file myProxyquire was called, and resolving the passed path relative to that file:

'use strict'; // this line is important and should not be removed

const callerPath           = require('caller-path');
const { dirname, resolve } = require('path');

module.exports.default = path => require(resolve(dirname(callerPath()), path));

However, I have no idea of this works with import (and, presumably, transpilers).
