proxyquire not stubbing метод call

Question

Я пытаюсь использовать proxyquire, чтобы заменить вызов метода в модуле, который я тестирую, но он вызывает метод, несмотря на то, что у меня установлен заглушка. Что я делаю не так?

formsReducer.test.js:

import { expect } from 'chai'; 
import * as actions from '../actions/formsActions'; 
import * as types from '../constants/actionTypes'; 
import proxyquire from 'proxyquire'; 

describe('Forms Reducer',() => { 
    describe('types.UPDATE_PRODUCT',() => { 
     it('should get new form blueprints when the product changes',() => { 
      //arrange 
      const initialState = { 
       blueprints: [ 
        { 
         id: 1, 
         categoryId: 1, 
         identifier: null, 
         name: "Investment Policy Statement", 
         sortGroup: 1, 
         wetSignRequired: false 
        } 
       ] 
      }; 
      const testBlueprints = [{ id: 999, categoryId: 1, name: "Form Blueprint Loaded From Product ID 1", sortGroup: 1, wetSignRequired: false }]; 
      //use proxyquire to stub call to formsHelper.getFormsByProductId 
      let formsReducer = proxyquire.noCallThru().load('./formsReducer', { 
       formsHelper: { 
       getFormsByProductId: id => { return testBlueprints } 
       } 
      }).default; 
      const action = { 
       type: types.UPDATE_PRODUCT, 
       product: { 
        id: 1, 
        accountTypeId: 1, 
        officeRangeId: 1, 
        additionalInfo: "", 
        enabled: true 
       }, 
      }; 
      //act 
      const newState = formsReducer(initialState, action); 
      //assert 
      expect(newState.blueprints).to.be.an('array'); 
      expect(newState.blueprints).to.equal(testBlueprints); 
     }); 
    }); 
}); 

formsReducer.js:

import * as types from '../constants/actionTypes'; 
import objectAssign from 'object-assign'; 
import initialState from './initialState'; 
import formsHelper from '../utils/FormsHelper'; 
export default function formsReducer(state = initialState.forms, action) { 
    switch (action.type) { 
    case types.UPDATE_PRODUCT: { 
     let formBlueprints = formsHelper.getFormsByProductId(action.product.id); 
     formBlueprints = formsHelper.addOrRemoveMnDisclosure(formBlueprints, action.stateOfResidence.id); 
     return objectAssign({}, state, {blueprints: formBlueprints, instances: []}); 
    } 
} 

formsHelper.getFormsByProductId не возвращается testBlueprints, как он должен, если он надлежащим образом погасил через proxyquire. Что я делаю не так?

formsReducer.js импортирует ../utils/FormsHelper, но proxyquire пытается заменить formsHelper. Попробуйте изменить прокси-запрос на:

proxyquire.noCallThru().load('./formsReducer', { 
    '../utils/FormsHelper': { 
    getFormsByProductId: id => { return testBlueprints } 
    } 
})
