Question

我已经开始尝试用jest为vue.js项目编写单元测试。我尝试过的所有其他功能都可以运行，除了在构建项目时允许使用一些import语句。

我尝试弄乱babel，jest，babel-jest和项目的配置文件，但是无论我尝试什么更改，它仍然会给我同样的错误。

示例单元测试失败：

import { mount } from '@vue/test-utils'
import EventShow from '@/views/EventShow.vue'

describe('EventShow', () => {
  test('Simple Test', () => {
    expect(3).toBe(3)
  })
  test('is a Vue instance', () => {
    const wrapper = mount(EventShow)
    expect(wrapper.isVueInstance()).toBeTruthy
  })
})

错误消息：

> jest __tests__
 FAIL  src/views/__tests__/TestEventShow.test.js
  ● Test suite failed to run

    Cannot find module '@/components/EventShow.vue' from 'TestEventShow.test.js'

      1 | import { mount } from '@vue/test-utils'
    > 2 | import EventShow from '@/components/EventShow.vue'
        | ^
      3 | 
      4 | describe('EventShow', () => {
      5 |   test('Simple Test', () => {

      at Resolver.resolveModule (node_modules/jest-resolve/build/index.js:230:17)
      at Object.<anonymous> (src/views/__tests__/TestEventShow.test.js:2:1)

为什么VS Code无法在Jest单元测试中识别出导入语句？
