安裝Firefox舊版本 - Linux機器 - 硒測試失敗的Firefox版本

我在Linux服務器上運行一些Selenium GUI測試（無頭），瀏覽器是Firefox。紅帽企業Linux服務器版本5.9（Tikanga）安裝Firefox舊版本 - Linux機器 - 硒測試失敗的Firefox版本

我使用yum安裝了FireFox版本，並在Selenium測試失敗時收到錯誤消息。 Firefox通過yum安裝的版本是：17.0.9版本。

錯誤消息如下。看起來像我們在許多項目中使用的Selenium webdriver/java/jar版本（2.39.0）對Firefox有依賴性，它與Firefox的更高版本> 26不兼容。因此，如果我可以以某種方式安裝Firefox版本26或24 - 26之間，我的測試將會奏效。 Selenium-java 2.39.0版本支持upto FIREFOX瀏覽器26，看起來好像安裝的「yum」版本太低了。

問題：

從哪裏可以下載Firefox版本26
我如何安裝Firefox版26使用「蔭」命令
我怎樣才能刪除現有的最新版本的Firefox從我的Linux機器。

錯誤消息亮點：

無法連接到二進制FirefoxBinary（在/ usr /斌/ Firefox）的上端口 OR
所致：org.openqa.selenium。 firefox.NotConnectedException：無法連接到主機127.0.0.1

答案：

https://ftp.mozilla.org/pub/mozilla.org/firefox/releases/26.0/linux-x86_64/en-US/ （發佈後，指定XX.X版本，操作系統類型/位類型和語言），你會發現 .tar.bz2格式格式包。後

，但 焦油-xvf且該版本的Firefox作爲/生產/火狐文件夾，當我跑步時：./firefox -version，我得到一個錯誤。 ENV變量LD_LIBRARY_PATH設置爲：/生產/ Firefox中：/ usr/lib中：在/ usr/local/lib目錄

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。我設法解決錯誤信息，因爲這是由於沒有顯示。我在Jenkins安裝了「xvfb」插件並啓用了它。現在，我沒有收到沒有顯示錯誤，但不同的。以下錯誤現在至少不會出現。

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：我不認爲我可以這樣做。我必須使用rpm（這會導致其他安裝問題）。

答3：百勝刪除火狐

這個崗位的整個目的是運行在Linux機器（無頭）上Selenium測試。

要解決這個問題，我所做的只是在Jenkins中安裝「Xvfb」插件。在Jenkins作業（運行測試/調用測試）中配置它。我選中了「Enable Xvfb」，Timeout（5）秒，Log Xvfb。不要檢查/勾選「讓Xvfb選擇顯示器＃」的框，否則會出現以下錯誤。

在詹金斯日誌：你會看到...而不是調用下面的（有效）命令

Xvfb starting$ Xvfb :3 -screen 0 1024x768x24 -fbdir /production/jenkinsAKS/2014-10-30_13-56-051887436837486829115xvfb

莫名其妙地當「讓Xvfb來選擇顯示」複選框..被選中，它有時不起作用，並給出如下所示的命令（帶有Xvfb的使用信息）。 PS「-displayfd 2」的說法是不正確：

Xvfb starting$ Xvfb -displayfd 2 -screen 0 1024x768x24 -fbdir /production/jenkinsAKS/2014-10-30_13-56-051887436837486829115xvfb

所以，取消讓Xvfb來選擇顯示框，你會被罰款（因爲它將使用：SomeNumber的參數，同時呼籲的Xvfb命令）。現在，Selenium GUI測試運行良好，不用擔心現有的17.0.9（由YUM安裝的firefox版本工作正常）的firefox版本。
