我正在尝试使用使用 硒* 和 chromedriver的
量角器 在 Jenkins 上运行一些自动化测试。
***

我还设置了 xvfb， 以便我们可以 无头 运行这些测试。我已经安装了 xvfb jenkins插件 ，并且可以正常工作。

错误

我遇到的问题是，当我开始测试时，chrome不断崩溃。我收到此错误：

E/launcher - WebDriverError: unknown error: Chrome failed to start: crashed
...
E/launcher - Process exited with error code 199

• Chrome参考：https：//sites.google.com/a/chromium.org/chromedriver/help/chrome-doesn-t-start
• 未知错误：Chrome无法启动：异常退出（驱动程序信息：chromedriver = 2.9建议配置xvfb
• WebDriverError：未知错误：Chrome无法启动：退出异常未解决
• https://github.com/seleniumhq/selenium-google-code-issue-archive/issues/8409建议使用直接连接：“量角器无需使用Selenium服务器即可直接针对Chrome和Firefox进行测试。要在配置中使用文件集directConnect：true。”
• Selenium Webdriver和Chrome驱动程序-无法运行Chrome驱动程序建议改用Java 1.6
• 远程Webdriver上的Chrome（通过Grid）无法启动，建议使用x64 chromedriver并在参数中指定
