我按照以下步骤开始使用硒中枢 . 启动selenium grid hub
- hub.json文件：
{
"port": 4441,
"newSessionWaitTimeout": -1,
"custom": {},
"capabilityMatcher":"org.openqa.grid.internal.utils.DefaultCapabilityMatcher",
"throwOnCapabilityNotPresent": true,
"cleanUpCycle": 5000,
"role": "hub",
"debug": false,
"browserTimeout": 0,
"timeout": 1800
}
- 我解雇了命令：
java -Dwebdriver.chrome.driver=E:\SELENIUM_DOWNLOADS\Drivers\chromedriver.exe -jar E:\SELENIUM_DOWNLOADS\Jars\selenium-server-standalone-3.11.0.jar -role hub -hubConfig hub.json
- 结果：
E:\>cd \selenium_practice\Maven_Workspace\DataDriven_zoho_18April2019_GRID
E:\selenium_practice\Maven_Workspace\DataDriven_zoho_18April2019_GRID>java -Dwebdriver.chrome.driver=E:\SELENIUM_DOWNLOADS\Drivers\chromedriver.exe -jar E:\SELENIUM_DOWNLOADS\Jars\selenium-server-standalone-3.11.0.jar -role hub -hubConfig hub.json
