Ошибка запуска Jest-теста с использованием vuejs -datepicker

Question

Я изучаю Jest с моим тестовым Vue приложением, и все идет хорошо, за исключением того, что в одном из моих components я использую vuejs-datepicker, и когда я запускаю тесты ниже, я получаю следующую ошибку, которую я Кажется, я не могу исправить ситуацию.

Тестовый файл

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

import ShowBlogs from '@/components/showBlogs.vue'
import ActiveBlogs from '@/components/blogsActive.vue'
import AddBlog from '@/components/addBlog.vue'
import ClosedBlogs from '@/components/blogsClosed.vue'

describe('ShowBlogs.vue tests', () => {
    let wrapper = null

    beforeEach(() => {
        wrapper = mount(ShowBlogs)
    })

    afterEach(() => {
        wrapper.destroy()
    })

    it('Checks "ShowBlogs" component rendered', () => {
        expect(wrapper.name()).toMatch('ShowBlogs')
    })

    it('Checks "Active" tab displayed on load', () => {
        expect(wrapper.find(ActiveBlogs).exists()).toBeTruthy()
    })

    it('Checks tab labels & correct tab has "Active" class', () => {
        expect(wrapper.find('h1').text()).toEqual('Articles')

        expect(wrapper.findAll('li').length).toEqual(3)
        expect(wrapper.findAll('li').at(0).text()).toEqual('Active blogs')
        expect(wrapper.findAll('li').at(1).text()).toEqual('Closed blogs')
        expect(wrapper.findAll('li').at(2).text()).toEqual('Add a new blog')

        expect(wrapper.find('#activeBlogs-tab').classes()).toContain('active')
    })

    it('Checks "ClosedBlogs" component displayed when clicking "Closed Blogs tab"', () => {
        wrapper.find('#closedBlogs-tab').trigger('click')
        expect(wrapper.find(ClosedBlogs).exists()).toBeTruthy()
    })
})

Jest encountered an unexpected token

This usually means that you are trying to import a file which Jest cannot parse, e.g. it's not plain JavaScript.

By default, if Jest sees a Babel config, it will use that to transform your files, ignoring "node_modules".

Here's what you can do:
 • To have some of your "node_modules" files transformed, you can specify a custom "transformIgnorePatterns" in your config.    
 • If you need a custom transformation specify a "transform" option in your config.
 • If you simply want to mock your non-JS modules (e.g. binary assets) you can stub them out with the "moduleNameMapper" config 

.

You'll find more details and examples of these config options in the docs:
https://jestjs.io/docs/en/configuration.html
