[Vuejs]-Vue.js input validation w VeeValidate – How to avoid onInput action while invalid

like you access the errors collection in the VUE template, you can also access the same errors collection in your testValidation method

so replace

const ariaInvalid = this.$refs.inputTitle.getAttribute('aria-invalid')

with

 const ariaInvalid = this.$validator.errors.has('title')
