How can I use expectDeprecation in addon tests? about ember-dev HOT 3 CLOSED

import {
  module,
  test
} from 'qunit';
import parseArgs from 'ember-ajax/utils/parse-args';
import createExpectDeprecationAssertion from '../../helpers/expect-deprecation';

let assertion;
module('utils/parse-args', {
  beforeEach() {
    assertion = createExpectDeprecationAssertion();
    assertion.inject();
  },
  afterEach() {
    if (assertion) {
      assertion.restore();
      assertion = null;
    }
  }
});

test('raises deprecation', function(assert){
  expectDeprecation(function(){
    let args = parseArgs.call(null, { url: '/posts'} );
  });
});
