如何在Ember中测试返回PromiseArray的计算属性

import { module, test } from 'qunit';
import { setupRenderingTest } from 'ember-qunit';
import { render } from '@ember/test-helpers';
import hbs from 'htmlbars-inline-precompile';
import { Promise } from 'rsvp';

module('Integration | Component | your-component', function(hooks) {
  setupRenderingTest(hooks);
});

test('should return PromiseArray from computed property', async function(assert) {
  assert.expect(1);

  // 模拟异步操作返回PromiseArray
  const promiseArray = Promise.resolve(['item1', 'item2']);
  this.set('promiseArray', promiseArray);

  await render(hbs`
    {{#each this.promiseArray as |item|}}
      <div>{{item}}</div>
    {{/each}}
  `);

  assert.equal(this.element.querySelectorAll('div').length, 2, 'Should render 2 items');
});

ember test --filter="your-test-file.js"
