【测试】Selenium Grid测试

Selenium Webdriver API
Selenium Grid 测试
专门用于在不同的浏览器、操作系统和机器上并行运行多个测试（兼容性测试）。

配置环境

下载http://selenium-release.storage.googleapis.com/index.html

启动Hub

-role hub表示启动运行hub；
-port是设置端口号，hub的默认端口是4444
-maxSession为最大会话请求，这个参数主要要用并发执行测试用例，默认是1

java -jar c:/third/selenium-server-standalone-3.5.3.jar -role hub -maxSession 10 -port 4444

验证Hub控制台

http://192.168.43.58:4444/

Nodes should register to http://192.168.43.58:4444/grid/register/

启动节点1

-role node：表示启动的是node节点
-port 5555：指定node节点端口
-hub http://localhost:4444/grid/register：表示hub机地址
-maxSession 5：node节点最大会话请求
-browser browserName=firefox,seleniumProtocol=WebDriver,maxInstances=5,platform=WINDOWS 设置浏览器的参数
maxInstances表示最大实例，最多可运行的浏览器数，不能大于前面maxSession的值

java -jar c:/third/selenium-server-standalone-3.5.3.jar -role node -port 5555 -hub http://localhost:4444/grid/register -maxSession 5 -browser browserName=firefox,seleniumProtocol=WebDriver,maxInstances=5

节点2

java -jar c:/third/selenium-server-standalone-3.5.3.jar -role node -port 6666 -hub http://localhost:4444/grid/register -maxSession 5 -browser browserName=chrome,seleniumProtocol=WebDriver,maxInstances=5
