The format-duration-test.js file looks like this:

import { moduleFor, test } from 'ember-qunit';
import moment from 'moment';

function convertToMS(amount, unit) {
  return moment.duration(amount, unit).asMilliseconds();
}

moduleFor('helper:format-duration', 'Integration | Helper | format duration', {
  integration: true,

  async beforeEach() {
    await this.container.lookup('service:intl').loadAndSetLocale('en');
  }
});

test('1 min', function(assert) {
  let helper = this.subject();

  let result = helper.compute([convertToMS(1, 'minute')]);

  assert.equal(result, '1 min');
});

test('59 min', function(assert) {
  let helper = this.subject();

  let result = helper.compute([convertToMS(59, 'minutes')]);

  assert.equal(result, '59 min');
});

test('1h00', function(assert) {
  let helper = this.subject();

  let result = helper.compute([convertToMS(1, 'hour')]);

  assert.equal(result, '1h00');
});

test('1h01', function(assert) {
  let helper = this.subject();

  let result = helper.compute([convertToMS(61, 'minutes')]);

  assert.equal(result, '1h01');
});

It looks like this is mainly an issue if integration: true is set even though the test is actually a unit test

[Robert Jackson]

I thought I had fixtures for this case (moduleFor + integration: true + this.subject()), maybe I missed it.
