Chromedriver 手动工作，但在来自 Jenkins Slave 的 运行 时失败

Question

我有一个 Jenkins 从节点设置 LinuxMint。因此，我们可以在 Chrome 和 Firefox 中的 Linux 框上进行一些浏览器测试。

我安装了最新的 Chrome 驱动程序，测试可以 运行 它并且当我手动进入 /var/jenkins/workspace/<project name>/TestAutomation/SeleniumFramework 并执行我的 run npm <test name> 测试时启动 chromedriver 运行 成功。

当我进入 Jenkins 并且 运行 我的测试 chromedriver 失败并出现以下问题，我不知道该去哪里。:

第一个解：

你java8安装了吗？如果是，卸载并安装 java 7.

第二种解法：

将量角器降级到 v1.8.0

我发现了一个与你相似的主题，在 jenkins 中出现了同样的错误 - linux:

In you jenkins settings add a global property

key : DISPLAY
value:0:0

On your server start Xvfb in the background:

Xvfb :0 -ac -screen 0 1024x768x24 &

link: unknown error: Chrome failed to start: exited abnormally (Driver info: chromedriver=2.9

Answer 2

所以我通过 SSH 从 Jenkins 主机连接到从机。这永远不会启动浏览器会话。我切换到 Java Web Start 选项，它启动浏览器就好了。
