Ember.js 用于在应用程序路由中呈现模式的Qunit

在我的申请过程中，我从ember网站上获得了关于如何呈现modals的打开和关闭的代码。

我一直在寻找如何对渲染操作进行单元测试的示例，但找不到太多文档

在我对应用程序路由的单元测试中，只是为了触发路由上的操作并查看会发生什么，这就是我所拥有的和我得到的错误。感谢您提供的任何指导

test('route open modal', function(assert) {
  let route = this.subject();
  route.send('openModal', 'cancel-modal');
  assert.ok(route);
});

两件事

您使用的是过时的解决方案。您链接到的文档页已存在两年

取而代之的是，在模态对话框中使用一个现代的插件。我个人更喜欢，但也有

您正在尝试呈现某些内容时使用单元测试。单元测试用于运行方法并检查其返回值。若要测试呈现的模式对话框，您需要接受测试

test('route open modal', function(assert) {
  let route = this.subject();
  route.send('openModal', 'cancel-modal');
  assert.ok(route);
});
