ember-test-with-data/test-support/helpers/ember-test-with-data/find-with-data.js

This Ember addon allows you to test using data attributes without sending it to live sites.

import Ember from 'ember';

const { Test: { registerHelper } } = Ember;

export default registerHelper('findWithData', (app, value = '', context=undefined) => {
  const config = app.resolveRegistration('config:ember-test-with-data') || {};
  const attr = config.attr;
  const selector = value ? `[${attr}=${value}]` : `[${attr}]`;
  return find(selector, context);
});
