我正在Linux服务器上运行一些Selenium GUI测试（无头），浏览器是Firefox。红帽企业Linux服务器版本5.9（Tikanga）
我使用 yum 安装了FireFox版本，并在Selenium测试失败时收到错误消息。通过yum安装的Firefox版本是：17.0.9版本。
错误消息如下。看起来我们在许多项目中使用的Selenium webdriver / java / jar版本（2.39.0）依赖于Firefox，它与更高版本的Firefox＆gt;不兼容。 26.因此，如果我可以以某种方式安装Firefox 26或24至26之间，我的测试将起作用。 Selenium-java 2.39.0版本支持最多的FIREFOX浏览器26，似乎安装的“yum”版本太低了。
问题：
错误消息突出显示：
无法连接到端口上的二进制FirefoxBinary（/ usr / bin / firefox）
或
引起：org.openqa.selenium.firefox.NotConnectedException：无法连接到主机127.0.0.1

答案 0 :(得分：0)
回答：
，但 在 tar -xvf 并将此版本的firefox作为 / production / firefox 文件夹后，当我正在运行时： ./ firefox -version ，我收到了错误。 ENV变量 LD_LIBRARY_PATH 设置为： / production / firefox：/ usr / lib：/ usr / local / lib
XPCOMGlueLoad error for file /production/firefox/libxul.so:
libgio-2.0.so.0: cannot open shared object file: No such file or directory
Couldn't load XPCOM.
另一件事。我设法解决了错误消息，因为没有显示。我安装了＆＃34; xvfb ＆＃34;在Jenkins插件并启用它。现在，我没有得到任何DISPLAY错误，而是一个不同的错误。现在至少还没有出现以下错误。
Failed to connect to binary FirefoxBinary(/usr/bin/firefox) on port 7055; process output follows: Error: no display specified Error: no display specified
答案2：我不认为我能做到这一点。我必须使用rpm（这会产生其他安装问题）。
答案3：yum erase firefox
这篇文章的全部目的是在Linux机器上运行Selenium测试（无头）。
要解决这个问题，我所做的就是安装＆＃34; Xvfb＆＃34;詹金斯的插件。在Jenkins作业（运行测试/调用测试）中配置它。我选中＆＃34;启用Xvfb＆＃34;，超时（5）秒，Log Xvfb的复选框。 不要检查/勾选方框＆＃34;让Xvfb选择显示＃＆＃34;或者您将收到以下错误。
在Jenkins日志中： 您将看到..而不是调用以下（有效）命令
Xvfb starting$ Xvfb :3 -screen 0 1024x768x24 -fbdir /production/jenkinsAKS/2014-10-30_13-56-051887436837486829115xvfb
以某种方式选中＆＃34;让Xvfb选中显示＆＃34; ..复选框时，它有时不起作用并给出如下给出的命令（带有Xvfb的使用信息）。 PS＆＃34; -displayfd 2＆＃34;参数不正确：
Xvfb starting$ Xvfb -displayfd 2 -screen 0 1024x768x24 -fbdir /production/jenkinsAKS/2014-10-30_13-56-051887436837486829115xvfb
所以，取消选中让Xvfb选择显示框，你就可以了（因为它在调用Xvfb命令时会在参数中使用：SomeNumber）。现在，Selenium GUI测试运行正常，不用担心哪个版本的firefox与现有的17.0.9（由YUM安装的firefox版本工作正常）。
