python+selenium grid配置与运行

发表于 更新于 分类于 阅读次数： Valine：

说明

本次主要介绍本地搭建一套selenium grid的环境

环境准备

  • java安装，以及环境配置
  • python 3.4环境
  • selenium安装 pip install selenium
  • Chromedriver 要和本地的chrome浏览器匹配,点击下载
  • 下载selenium-server-standalone点击下载
  • 准备2台pc，如果是虚拟机，选择桥接，2台pc互相能ping通,本次测试为本机

开始部署

  • 启动hub
1
java -jar selenium-server-standalone-v3.0.1.jar -role hub -port 4455

  • 启动node

java -jar selenium-server-standalone-v3.0.1.jar -role node -port 5555 -hub http://192.168.0.102:4444/grid/registe

java -jar selenium-server-standalone-v3.0.1.jar -role node -port 6666 -hub http://192.168.0.102:4444/grid/registe

  • 其他node启动方式

java -Dwebdriver.ie.driver=D:\IEDriverServer.exe -jar selenium-server-standalone-2.37.0.jar -role node -hub [http://127.0.0.1:4444/grid/register](http://127.0.0.1:4444/grid/register) -maxSession 20 -browser "browserName=internet explorer,version=9,platform=WINDOWS,maxInstances=20" -port 5555

node是只运行IE，并且并发数是20，最多有20个IE浏览器在运行

查看grid信息

浏览器打开：http://hub_ip:4444/grid/console 可以查看hub信息，和已经连上的node信息
