Ionic 2：测试和图像错误

Question

我尝试使用 Jasmine 和 Karma 测试我的 Ionic 2 应用程序。 当我运行“npm test”时出现此错误：

C:\xampp\htdocs\MyApp>npm test

> ionic-hello-world@ test C:\xampp\htdocs\MyApp
> karma start ./test-config/karma.conf.js

问题是我的项目中图像的路径。我不明白为什么，但它像模块一样体贴。

事实上，如果我删除项目中的所有图像路径，测试就可以工作。但我需要保留我的图像...

在我的 html 中有一个图片路径的例子：

<ion-content padding>
  <div class="loading-screen">
    <img src="assets/images/logo-yellow.svg"><br><br>
    <label>{{this.translate.get('mod-appFine-data_loading')}}</label><br>
    <label>{{this.translate.get('mod-appFine-thanks_wait')}}</label><br>
    <ion-spinner name="crescent" ></ion-spinner>
  </div>
</ion-content>

有人想解决这个问题吗？

我的解决方案是在 var 中找到正确的路径并在我的代码中调用此 var。它对我有用。
