注意:StartSeleniumGridHub.bat 完美地 运行。 Firefox 也没有问题。
请更改
java -jar selenium-server-standalone-3.4.0.jar -role node -hub http://127.0.0.1:4444/grid/register -browser "browserName=firefox,maxInstances=3,platform=WINDOWS" -browser "browserName=chrome,maxInstances=2,platform=WINDOWS" -Dwebdriver.chrome.driver="D:\SeleniumGridPractice\drivers\chromedriver.exe"
到
java -Dwebdriver.chrome.driver="D:\SeleniumGridPractice\drivers\chromedriver.exe" -jar selenium-server-standalone-3.4.0.jar -role node -hub http://127.0.0.1:4444/grid/register -browser "browserName=firefox,maxInstances=3,platform=WINDOWS" -browser "browserName=chrome,maxInstances=2,platform=WINDOWS"
然后重试。
解释:
JVM 参数(以 -D
开头的参数)应该在 -jar
参数之前提供。但是由于您在 -jar
之后提供了它,而不是将其视为 JVM 参数,因此它被作为命令行参数提供给 selenium-server
独立 jar。
