Unit testing 使用Jest测试Vuex存储模块

我是用笑话测试vue的初学者。 我想测试下面描述的vuex模块

bible.mudule.js

export const mutations = {
   setTestament(state, testament) {
     state.testament = testament;
   },
   setBookList(state, list) {
     state.bookList = list;
   },
   setCurrentBook(state, book) {
     state.currentBook = book;
   },
   setCurrentChapterNumber(state, chapter) {
    state.currentChapterNumber = chapter;
   }
 }

export const actions = {
    retrieveBooksByTestament( { commit } , testament) {
        BibleService.retrieveBooksByTestament(testament).then(bookList => {
            commit('setBookList', bookList);
         })
    },
    changeCurrentBook({ commit }, book) {
       commit('setCurrentBook', book);
       commit('setCurrentChapterNumber', 1);
    },
    setTestament({ commit }, testament) {
       commit('setTestament', testament);
    }
 }

export const bible = {
  namespaced: true,
  state: {
      testament: null,
      bookList: null,
      currentBook: null,
      currentChapterNumber: null

  },
  mutations: mutations,
  actions: actions,  
}

index.js

import Vue from 'vue'
import Vuex from 'vuex'
import createPersistedState from "vuex-persistedstate";
import { bible } from "./bible/bible.module";

Vue.use(Vuex)

export default new Vuex.Store({
   modules: {
    bible,
   },
   plugins: [createPersistedState()]
});

我试着写一个测试如下

import { shallowMount, createLocalVue } from '@vue/test-utils'
import ListOfBooksScreen from '../../src/views/ListOfBooksScreen.vue'
import BibleService from '../../src/services/BibleService'
import Vuex from 'vuex'
import bible from '../../src/store/bible/bible.module'

const localVue = createLocalVue()
localVue.use(Vuex)

describe('ListOfBooksScreen.vue', () => {
  let actions
  let store
  window.prompt = jest.fn();

  beforeEach(() => { 
    actions = {
      retrieveBooksByTestament: jest.fn().mockName('retrieveBooksByTestament'),
      setTestament: jest.fn()
    }

    store = new Vuex.Store({
      components: {
        bible: {
          actions,
          namespaced: true
        }
      }
    }) 
  })  

  it('calls store action "retrieveBooksByTestament" when is mounted', async () => {
    const wrapper = shallowMount(ListOfBooksScreen, { store, localVue});
    expect(actions.retrieveBooksByTestament).toHaveBeenCalled();
  }) 
})

但是我得到了下面的错误

console.error node_modules/vuex/dist/vuex.common.js:1132
[vuex] module namespace not found in mapState(): bible/

console.error node_modules/vuex/dist/vuex.common.js:1132
[vuex] module namespace not found in mapActions(): bible/

另外，在我的组件中，RetrieveBooksByTestation方法是在挂载的钩子上调用的，因此我考虑

expect(actions.retrieveBooksByTestament).toHaveBeenCalled() 

返回true，但从未调用该操作，测试失败并显示以下消息

Expected number of calls: >= 1
Received number of calls:    0

关于第一个问题，我知道这是由于与名称空间相关的原因，但我找不到问题所在。我正在查看vuex文档，它似乎没有问题。 关于第二个问题，我真的不知道测试是否提出得很好
