Question

我的selenium grid 3.0.1设置有一个集线器和三个节点，如下所示：

第一个节点：使用Chrome和Firefox的Linux
第二个节点：带有Chrome，Firefox，Edge和Internet Explorer的Windows 10
第三个节点：使用Android模拟器运行Appium的Linux

由于某种原因，网格不会根据平台和浏览器智能地选择节点。

我特别关注IE和Appium。

我用以下方式启动集线器：

nohup java -cp selenium-video-node-2.1.jar:selenium-server-standalone-3.0.1.jar org.openqa.grid.selenium.GridLauncherV3 \
 -servlets com.aimmac23.hub.servlet.HubVideoDownloadServlet \
 -role hub \
 2>&1 > logs/hub.log &

我启动我的linux节点，例如：

nohup java -Dwebdriver.chrome.driver="/home/ubuntu/testcloud/webdrivers/chromedriver" \
       -Dwebdriver.chrome.bin="/usr/bin/opera" \
       -Dwebdriver.chrome.logfile="/home/ubuntu/testcloud/logs/chrome.log" \
       -Dwebdriver.gecko.driver="/home/ubuntu/testcloud/webdrivers/geckodriver" \
       -Dwebdriver.firefox.bin="/home/ubuntu/testcloud/browsers/firefox/firefox" \
       -Dwebdriver.firefox.logfile="/home/ubuntu/testcloud/logs/firefox.log" \
       -cp selenium-video-node-2.1.jar:selenium-server-standalone-3.0.1.jar org.openqa.grid.selenium.GridLauncherV3 \
       -servlets com.aimmac23.node.servlet.VideoRecordingControlServlet -proxy com.aimmac23.hub.proxy.VideoProxy \
       -role wd -hub "http://172.31.1.65:4444/grid/register/" \
  2>&1 > logs/selenium.log &

我使用以下命令在python中配置驱动程序：

d=DesiredCapabilities.INTERNETEXPLORER.copy()
d['loggingPrefs']={ 'browser': 'ALL' }
d["platform"]="WINDOWS"
driver = webdriver.Remote(
    command_executor="http://"+HUB+":4444/wd/hub",
    desired_capabilities=d
)
driver.maximize_window()
driver.implicitly_wait(30)

当我使用此配置运行测试时，每3次中有2次，其他节点会响应以下内容：

    Traceback (most recent call last):
  File "test_appium.py", line 15, in <module>
    driver = webdriver.Remote('http://35.154.75.140:4444/wd/hub', desired_caps)

有人可以帮我解决这个问题吗？

发现问题。

我希望Selenium Grid能够自动检测平台和浏览器并相应地进行路由。

看起来并非如此，您需要定义一个JSON节点配置，该配置指定匹配的功能。一个很好的例子是here。
