key.charAt는 createLocalVue()의 함수 오류가 아닙니다.

key.charAt는 createLocalVue()의 함수 오류가 아닙니다.

createLocalVue 함수를 사용하면 TypeError: key.charAt는 함수가 아닙니다.흥미로운 점은 모든 컴포넌트 테스트에서 localVue를 사용하는 동안 일부 컴포넌트의 경우만 입력된다는 것입니다.테스트 코드 예를 다음에 나타냅니다.

import assign from 'lodash/assign'
import { mount, createLocalVue } from '@vue/test-utils'
import filters from '@/filters'
import { DateUtils } from '@/filters/date-utils'
import TaskCard from '@/components/molecules/TaskCard'
