Poor Man's Dependency Injection

depInj.js

import dep1 from '../dep1';
import dep2 from '../dep2';

const defaultDeps = {
  dep1,
  dep2,
};

export function _myModuleFactory({ dep1, dep2 } = defaultDeps) {
  const myModule = {};
  // Module code here
  return myModule;
}

export default _myModuleFactory();

depInj.spec.js

import { _myModuleFactory } from './depInj.js';

const mockDep1;
const mockDep2;

const testableMyModule = _myModuleFactory({
  dep1: mockDep1,
  dep2: mockDep2,
});
