Ember Qunit acceptance test cases failing for application home page

1) I'm using acceptance test cases using Qunit for my home or Landing page.
2) I used all my home page logic in application.js route.
3) I created application-test file. Below are code.

import { test } from 'qunit';
import moduleForAcceptance from 'landingui/tests/helpers/module-for-acceptance';

moduleForAcceptance('Acceptance | application');

test('visiting /', function (assert) {
    visit('/');

    andThen(function () {
        assert.equal(currentURL(), '/');
    });
});

4) When I run my test cases its failing. Below are error which occurred.
