Incorrect (old testing patterns):

// tests/integration/components/user-card-test.js
import { module, test } from 'qunit';
import { setupRenderingTest } from 'ember-qunit';
import { render, find, click } from '@ember/test-helpers';
import UserCard from 'my-app/components/user-card';

module('Integration | Component | user-card', function (hooks) {
  setupRenderingTest(hooks);

  test('it renders', async function (assert) {
    await render(<template><UserCard /></template>);

    // Using find() instead of qunit-dom
    assert.ok(find('.user-card'));
  });
});
