How to unit test Vue components in a Laravel application?

Question

Unit testing

I did everything as the documentation says: Testing - Vue.js .

Here are the JEST settings in package.json:

"jest": {
    "moduleFileExtensions": [
        "js",
        "json",
        "vue"
    ],
    "transform": {
        ".*\\.(vue)$": "<rootDir>/node_modules/vue-jest",
        "^.+\\.js$": "<rootDir>/node_modules/babel-jest"
    },
    "collectCoverage": true,
    "collectCoverageFrom": ["**/*.{js,vue}", "!**/node_modules/**"]
},

Here is the test:

import { mount } from '@vue/test-utils'
import OrdersIndex from "../components/orders/OrdersIndex"

describe('Component OrdersIndex', () => {
    test('является экземпляром Vue', () => {
        const wrapper = mount(OrdersIndex)
        expect(wrapper.isVueInstance()).toBeTruthy()
    })
})

But when the command is executed npm test, JEST swears at all exports and imports in all components.
