Question

我正在尝试通过Jenkins使用FireFox Webdriver运行UI测试。我使用xvfb模拟浏览器，因为构建框没有显示。

我遇到了以下错误：

org.openqa.selenium.remote.UnreachableBrowserException: Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure. (user: 'UnknownUser-0', output: '1423245467418')

Xvfb在构建开始之前如下所示开始，这是使用Jenkins的xvfb插件配置的：

Xvfb starting$ /usr/bin//Xvfb :10 -screen 0 1024x768x24 -fbdir /srv/jenkins/xvfb-2015-02-06_12-57-37-3245666068187787922.fbdir

我确保Firefox在PATH中。

有人可以告诉我如何解决它吗？

首先通过在本地测试来修复Firefox版本和selenium版本匹配。如果您正在通过Jenkins运行作业并且在日志中出现错误，则无法在45000 ms后在端口7055上连接到主机127.0.0.1。 Firefox控制台输出：错误：无法打开显示:: 0

要解决以下步骤：

1）只有在Xvfb运行时才会启动Firefox 示例：Xvfb：15-screen 0 1024x768x16所以首先检查一下，这个检查可以通过将ps -ef添加到作业的预执行（shell执行）中来包含到作业中。 Xvfb：15-screen 0 1024x768x16＆amp;您可能会遇到必须以无头模式启动测试的主机/节点。

2）即使您明确定义了DISPLAY值但仍有错误，那么最好的方法是在Jenkin作业本身注入环境值。在构建环境＆gt;＆gt;下注入env变量＆gt;＆gt;属性内容＆gt;＆gt; DISPLAY =：15（您可以根据自己的选择显示，但同样应该在xvfb中运行）

!!运行你的工作，应该已经解决了。
