How to use the @ember/test-helpers.getContext function in @ember/test-helpers

export default function getRfc232TestContext() {
  // Support older versions of `ember-qunit` that don't have
  // `@ember/test-helpers` (and therefore cannot possibly be running an
  // rfc232/rfc268 test).
  if (require.has('@ember/test-helpers')) {
    let { getContext } = require('@ember/test-helpers');
    return getContext();
  }
}

export function getTools() {
  return getContext().owner.lookup('service:cardstack-tools');

return getSpaceForCard(type, id).then(space => {
    let context = getContext();
    let card = space.get('primaryCard');
    let params = space.get('params');
    context.set('card', card);
    context.set('format', format);
    context.set('params', Object.assign({}, params, options.params || {}));

    if (options.width) {
      context.set('widthStyle', htmlSafe(`width: ${options.width}`));
      return render(hbs`
      <div style="{{widthStyle}}">
        {{cardstack-content content=card format=format params=params }}
      </div>`);
    } else {
      return render(hbs`{{cardstack-content content=card format=format params=params }}`);
    }
  });

export function getSpaceForCard(type, id) {
  return getContext()
    .owner.lookup('service:store')
    .findRecord('space', `/${pluralize(type)}/${id}`);
}
