我正在測試元件 ComponentA.spec.js，但收到 TypeError: Cannot read property 'type' of null。如果我去掉 ComponentA 中 getData() 函數中的 wait 關鍵字，它就會運作。我在測試中模擬了 getData api 調用，但它仍然不起作用。

這是完整的堆疊 類型錯誤：C：[隱私權]\未知：無法讀取 null 的屬性「類型」

at assert (node_modules/@babel/types/lib/asserts/generated/index.js:284:112) 在 Object.assertIdentifier (node_modules/@babel/types/lib/asserts/generated/index.js:373:3) at new CatchEntry (node_modules/regenerator-transform/lib/leap.js:93:5) at Emitter.Ep.explodeStatement (node_modules/regenerator-transform/lib/emit.js:535:36) at node_modules/regenerator-transform/lib/emit.js:323:12 at Array.forEach () at Emitter.Ep.explodeStatement (node_modules/regenerator-transform/lib/emit.js:322:22) at Emitter.Ep.explode (node_modules/regenerator-transform/lib/emit.js:280:40) 

這是我正在嘗試為其創建測試的組件 A

這是我的 ComponentA.spec.js 檔案

import Vuetify from 'vuetify'; import ComponentA from 'components/ComponentA'; import { createLocalVue, shallowMount, mount } from '@vue/test-utils'; jest.mock('shared/apis', () => { const data = require('../fixedData/data.json'); return { getData: jest.fn().mockResolvedValue(data), }; }); const localVue = createLocalVue(); let vuetify; function createShallowWrapper(options = {}) { return shallowMount(ComponentA, { localVue, vuetify, ...options, }); } beforeEach(() => { vuetify = new Vuetify(); }); describe('ComponentA', () => { describe('component creation', () => { test('testing', () => { const wrapper = createShallowWrapper(); expect(wrapper).toMatchSnapshot(); }); }); });
