javascript - 如何在 Amazon Linux AMI 上运行端到端测试？

Question

我正在使用 Protractor 运行端到端测试，并且在 Ubuntu 上的 Chrome 和 Firefox 中一切运行良好。当我尝试使用 PhantomJS 运行测试时，它说无法找到元素。我正在使用 Angular v1.2.15。我的目标是在 Amazon Linux AMI 上运行测试，因此我要么必须让 PhantomJS 工作，要么安装 Chrome 或 Firefox，这看起来非常复杂。我了解到 PhantomJS 并不适合在 EC2 实例上进行测试，但是我应该使用哪种浏览器吗？这是我得到的错误和堆栈跟踪:

我在云中使用 headless selenium服务器，即使没有真正的DISPLAY，它也提供Chrome和Firefox。我刚刚将配置文件移至此处:https://github.com/elgalu/headless
