SyntaxError: Unexpected token < when trying to test with AVA

Question

My original problem appeared in the project based on nuxt. Trying to solve it I set up a new project via vue-cli, and installed AVA via npm again, but it didn't change anything. I found this issue (https://github.com/nuxt/nuxt.js/issues/438) on github, which one of the comments (Atinux's, from 25th of March) seems to anwser my question, but when I try to go to mentioned link I get 404. Issue author says thet he would never have thought of using full path, but I don't really get what place he means exactly.

I also tried few different component syntaxes, but as I understand the problem is in AVA setup, because the problem is in the first "<" sign from tag. When I'm not trying to import my component and use simple test.('test 2', t => t.pass()) everything is fine and test passes alright. I would be very grateful for any tips on this issue!

My HelloWorld.vue file:

    <template>
  <div class="hello">
    <h1>{{ msg }}</h1>
  </div>
</template>

<script>
export default {
  name: 'HelloWorld',
  data () {
    return {
      msg: 'Vue app'
    }
  }
}
</script>

My HelloWorld.test.js file:

import test from 'ava'
import HelloWorld from './HelloWorld.vue'

test('message is Hello World', t => {
  t.is(HelloWorld.name, 'HelloWorld')
})

test('message is Hello World', t => {
  t.is(HelloWorld.$data.msg, 'Vue app')
})

I don't see anything in your configuration that tells the test processes how to load the .vue files. https://github.com/avajs/ava/blob/master/docs/recipes/vue.md should have more information.
