Heredé un código base que se creó usando @vue/cli originalmente no había una prueba unitaria en el proyecto y ahora estoy tratando de agregarlo, hasta ahora he creado una prueba muy simple y también agregué bromas a la aplicación.

Mi prueba simple se ve así,

 import { createLocalVue, mount, shallowMount } from '@vue/test-utils'; import ModalRefactored from '../../src/components/modal2/ModalRefactored.vue'; const localVue = createLocalVue(); describe('ModalRefactored', () => { let storeMocks, wrapper; beforeEach(() => { // Create a fresh store and wrapper instance for every test case. wrapper = shallowMount(ModalRefactored, { localVue }); }); test('It should render a modal when open', () => { }); test('It should not render an overlay when not open', () => { }); test('It should close whn the user clicks the close button', () => { }); test('It should close when the user presses the esc key', () => { }); });

Mi configuración de broma se ve así,

 module.exports = { preset: '@vue/cli-plugin-unit-jest' }

Cuando ejecuto yarn test:unit obtengo lo siguiente,

 ests/unit/ModalRefactored.spec.js

● No se pudo ejecutar el conjunto de pruebas

¿No tengo idea cual es el problema? ¿Supongo que usar el shallowMount ejecutaría la prueba de forma independiente?
