Question

我正在一个angularjs项目中工作，我用量角器构建测试。我想用Jenkins自动化我的测试。我写了一个小的shell脚本来启动我的测试，它在我的终端上运行良好。但是当我尝试从Jenkins启动脚本时，我遇到了一个问题。在jenkins控制台中，我可以看到此错误消息：

等等...... 10秒

由于这个问题，我完全被阻止了。你有什么线索可以解决这个问题吗？感谢y＆＃39;所有！

Answer 1

根据该错误，您的配置中似乎有directConnect: true。 Jenkins无法直接连接到浏览器驱动程序，因此请删除该行。

你也在使用localhost，也不认为詹金斯可以使用它。您可能需要远程selenium服务器。

这是一篇关于针对Windows VM运行Protractor的博客文章（它专注于针对Internet Explorer运行，但提供了围绕整个过程的大量有用信息）http://elgalu.github.io/2014/run-protractor-against-internet-explorer-vm/

Answer 2

UnknownError：未知错误：Chrome无法启动：异常退出

可能是因为很多情况。只需确保，jenkins slave有一些显示（真实或虚拟）。一般来说，jenkins奴隶没有真正的显示器，因此我们必须启动一些虚拟显示器，如xvfb，以便使selenium工作。如果selenium没有找到任何虚拟显示，chrome会抱怨同样的错误：无法启动。

但也有许多其他原因。
