seleniumGrid分散式遠端執行測試指令碼

執行UI自動化測試指令碼時,不僅可以在本地執行,也可以遠端指定某計算機執行測試指令碼,seleniumGrid為我們提供了這類服務,但還需要自己搭建環境。

一、本地計算機需要準備java環境和selenium-server-standalone-4.0.0-alpha-2.jar包,jar包主要開啟本機的hub節點(理解成控制機)。紅色部分是開啟本機(控制機)節點,藍色部分是開啟遠端node節點時需要連線控制機地址

       控制機地址

λ java -jar selenium-server-standalone-4.0.0-alpha-2.jar -role hub

11:05:41.358 INFO [Hub.start] - Clients should connect to http://192.168.20
7.1:4444/wd/hub

二、遠端機(我用的ubuntu系統)需要準備java環境和selenium-server-standalone-4.0.0-alpha-2.jar包,以及瀏覽器驅動(我用的firefox的驅動)。記住瀏覽器驅動需要新增到系統環境變數中:export PATH="$PATH:/usr/local/bin"。在遠端機啟動node節點:java -jar selenium-server-standalone-4.0.0-alpha-2.jar -role node -port 32100 -hub http://192.168.207.1:4444/grid/register/(開啟遠端節點並連線控制機),連線成功後,在控制機的dos視窗可以看到綠色部分,表示遠端機與控制機連線成功。

λ java -jar selenium-server-standalone-4.0.0-alpha-2.jar -role hub
11:05:38.938 INFO [GridLauncherV3.parse] - Selenium server version: 4.0.0-a

三、python指令碼。主要用到selenium.webdriver.remote.webdriver的WebDriver類完成遠端執行指令碼的任務。第一個引數是遠端計算機的ip與連線埠,第二個引數是執行指令碼的瀏覽器名稱。

driver=webdriver.WebDriver(command_executor='http://0.0.0.0:0/wd/hub',desired_capabilities={ "browserName": "firefox"})             

#friefoxdriverexport PATH="$PATH:/usr/local/bin"
