安装 firefox 旧版本 - Linux 机器 - Firefox 版本的 Selenium 测试失败答案

【问题标题】：Install firefox old version - Linux machine - Selenium tests fail for firefox version安装 firefox 旧版本 - Linux 机器 - Firefox 版本的 Selenium 测试失败
【发布时间】：2014-12-25 10:57:30
【问题描述】：

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。

错误信息如下。似乎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 > 26 不兼容。因此，如果我能以某种方式安装 Firefox 版本26 或 24 - 26 之间，我的测试将起作用。 Selenium-java 2.39.0 版本支持高达 26 的 FIREFOX 浏览器，安装的“yum”似乎版本太低了。

问题：

从哪里可以下载 Firefox 26 版
如何使用“yum”命令安装 Firefox 26 版
如何从我的 Linux 机器上删除现有的最新版本的 Firefox。

错误信息突出显示：

无法连接到端口上的二进制 FirefoxBinary(/usr/bin/firefox) 或
原因：org.openqa.selenium.firefox.NotConnectedException：无法连接到主机 127.0.0.1

【解决方案1】：

回答：

https://ftp.mozilla.org/pub/mozilla.org/firefox/releases/26.0/linux-x86_64/en-US/ （发布后，指定你的 xx.x 版本、操作系统类型/位类型和语言）你会发现 .tar.bz2 格式包。

但是，在 tar -xvf 之后并将这个版本的 firefox 作为 /production/firefox 文件夹，当我运行时：./firefox -version，我收到一个错误。 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，因为它是由于NO DISPLAY。我在 Jenkins 中安装了“xvfb”插件并启用了它。现在，我没有收到 NO DISPLAY 错误，而是另一个错误。至少现在不会出现以下错误。

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：我认为我做不到。我必须使用 rpm（这会导致其他安装问题）。

答案 3：yum erase firefox

这篇文章的全部目的是在 Linux 机器（无头）上运行 Selenium 测试。

为了解决这个问题，我所做的只是在 Jenkins 中安装“Xvfb”插件。在 Jenkins 作业中配置它（正在运行测试/调用测试）。我选中了“启用 Xvfb”、超时 (5) 秒、记录 Xvfb 复选框。请勿选中/勾选“让 Xvfb 选择显示#”框，否则您将收到以下错误。

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

不知何故，当“让 Xvfb 选择显示器”的复选框被选中时，它有时不起作用并给出如下所示的命令（带有 Xvfb 的使用信息）。 PS“-displayfd 2”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 选择显示框就可以了（因为它会在调用 Xvfb 命令时在参数中使用 :SomeNumber）。现在，Selenium GUI 测试运行良好，无需担心现有 17.0.9 版本的 firefox（YUM 安装的 firefox 版本运行良好）。
