运行Firefox的Xvfb和thucydides/Selenium默认路径

Question

CI Jenkins正在CentOS无头机器上运行，使用非根用户。

当我尝试How can I specify a display?的提示时，即在控制台中手动设置Xvfb。

export DISPLAY=127.0.0.1:0
Xvfb :0
firefox &

而且它可以工作- Xvfb输出显示一些firefox请求，Firefox输出到控制台。

当我从maven运行相同的程序时，什么都不会发生。请查看我的pom.xml：

firefox和Xvfb实用程序属于jenkins linux用户和chmoded 777，因此权限不是问题的根源。

export DISPLAY=127.0.0.1:0

设置为预生成操作。Xvfb应该由maven selenium插件启动，它是根据mavn输出和自己的Xvfb日志启动的。

我想知道Thucydides/Selenium如何定义如何找到要运行的Firefox二进制文件？也许应该在jenkins配置文件中显式地配置它们吗？

Answer 1

实际上，我无法以我喜欢的方式解决这个问题，因为尽管有任何显示变量的组合，将文件和二进制文件归因于jenkins用户并返回到root，从maven插件配置中运行Xvfb是不可能的。但是，插件工作得很好！如果对我来说更完美，因为我不再需要在本地机器和CI上运行不同的mvn配置文件(插件的Xvfb运行存储为jenkins配置文件)，
