Testing with Jest: SyntaxError: Unexpected identifier

Hi guys,

I am trying to test a component which uses VueAgile locally register and I am getting the following error:

/Users/gustavobissolli/Code/chatfood-webview/node_modules/vue-agile/src/index.js:1
    ({"Object.<anonymous>":function(module,exports,require,__dirname,__filename,global,jest){import VueAgile from './Agile'
                                                                                                    ^^^^^^^^

This is my component:

<template>
  <div class="container-fluid p-0" v-if="isComponentVisible">
    <Carousel
      :autoplay="true"
      :autoplaySpeed="5000"
      :speed="500"
      :navButtons="false"
      :unagile="activeCarousel"
    >
      <LoyaltyProgram
        v-if="hasLoyaltyProgram"
        :rewardPoints="rewardPoints"
        :loyaltyProgram="loyaltyProgram"
      />
      <div class="px-3" v-if="note">
        <div class="alert alert-success mb-0 px-3" v-html="note" />
      </div>
    </Carousel>
  </div>
</template>

<script>
import LoyaltyProgram from "./LoyaltyProgram";
import { VueAgile } from "vue-agile";
import { isEmpty, isNil } from "ramda";

export default {
  components: {
    Carousel: VueAgile,
    LoyaltyProgram
  },
  props: {
    note: {
      type: String,
      default: () => null
    },
    rewardPoints: {
      type: Number,
      default: () => 0
    },
    loyaltyProgram: {
      type: Object,
      default: () => {}
    }
  },
  computed: {
    hasLoyaltyProgram() {
      return !isEmpty(this.loyaltyProgram);
    },
    isComponentVisible() {
      return this.hasLoyaltyProgram || !isNil(this.note);
    },
    activeCarousel() {
      return !this.note || !this.hasLoyaltyProgram;
    }
  }
};
</script>

Any idea on how to fix it?

For anyone using nuxt, I had the same error. Adding vue-agile to the transpile options in nuxt.config.js fixed it:

build: {
    transpile: [
      'vue-agile'
    ],
}

Thanks @JakeBeresford for clueing me in on the fix!

I have found a solution to this problem. In your jest configuration you need to exclude vue-agile from the transformIgnorePatterns like this

transformIgnorePatterns: [ '/node_modules/(?!vue-agile)' ],
