selenium 网格监听节点端口而不是集线器端口

selenium grid listening on node port instead of hub port(selenium 网格监听节点端口而不是集线器端口)

本文介绍了selenium 网格监听节点端口而不是集线器端口的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

对于我的测试,我在不同的端口上本地运行网格和节点.

For my test, I am running grid and node locally on different ports.

java -jar /usr/bin/selenium-server.jar -port 4444 -role hub
java -jar /usr/bin/selenium-server.jar -role node -hub http://127.0.0.1:4444/grid/register -port 5556

因此,网格在 4444 上运行,节点在 5556 上运行.

So, the grid is running on 4444 and node is running on 5556.

在我的测试中,如果我启动驱动程序

In my test, if i start the driver as

driver = webdriver.Remote(command_executor='http://127.0.0.1:4444/wd/hub', desired_capabilities=desired_capabilities)

那么测试失败并出现异常

then the test fails with the exception

response = {'status': 500, 'value': '{"status":13,"value":{"class":"java.lang.NullPointerException","stackTrace":[{"fileName":"Ha...n","lineNumber":590},{"fileName":"Thread.java","className":"java.lang.Thread","methodName":"run","lineNumber":745}]}}'}

如果我在节点端口 5555 而不是集线器端口 4444 上运行测试,则测试通过,如下所示

The test passed if i run the test on the node port 5555, instead of the hub port 4444, as shown below

driver = webdriver.Remote(command_executor='http://127.0.0.1:5555/wd/hub', desired_capabilities=desired_capabilities)

我认为,我们应该在集线器端口上运行测试,在本例中是 4444 而不是 5555.

I was of the opinion that, we should be running the tests on the hub port, which in this case is 4444 and not 5555.

如果我错了,请纠正我.

Please correct me if i am wrong.

推荐答案

如果你打算在Grid中使用Selenium配置通过HubNode配置,我建议你使用最新的selenium-server-standalone-3.6.0 jar如下:

If you intend to use Selenium in Grid configuration through Hub and Node configuration, I would suggest you to use the most recent selenium-server-standalone-3.6.0 jar as follows:

  1. 启动 Selenium Grid Hub(默认在端口 4444):

  1. Start the Selenium Grid Hub (by default on port 4444) :

java -jar selenium-server-standalone-3.6.0.jar -role hub

  • 确认 Selenium Grid Hub 已启动:

  • Confirm the Selenium Grid Hub is started:

    16:06:29.891 INFO - Nodes should register to http://192.168.1.48:4444/grid/register/
    16:06:29.891 INFO - Selenium Grid hub is up and running
    

  • 访问 Selenium Grid Hub 控制台 并确保 Selenium Grid Hub 已启动并运行:

  • Access the Selenium Grid Hub Console and ensure Selenium Grid Hub is up and running:

    http://localhost:4444/grid/console
    

  • 为 Mozilla/GeckoDriver 启动 Selenium Grid Node(默认在端口 5555):

  • Start the Selenium Grid Node (by default on port 5555) for Mozilla/GeckoDriver:

    java -Dwebdriver.gecko.driver=geckodriver.exe -jar selenium-server-standalone-3.6.0.jar -role node -hub http://localhost:4444/grid/register
    

  • 确认Selenium Grid Node已注册并启动:

  • Confirm the Selenium Grid Node is registered and started:

    16:15:54.696 INFO - Selenium Grid node is up and ready to register to the hub
    16:15:54.742 INFO - Starting auto registration thread. Will try to register every 5000 ms.
    16:15:54.742 INFO - Registering the node to the hub: http://localhost:4444/grid/register
    16:15:54.975 INFO - The node is registered to the hub and ready to use
    

  • 使用 DesiredCapabilities 执行 Testcase,如下所示:

  • Execute with the Testcase with DesiredCapabilities as follows:

    self.driver = webdriver.Remote(command_executor='http://127.0.0.1:4444/wd/hub', desired_capabilities=caps)
    

  • 在您的 Testcase 成功执行时,观察以以下结尾的控制台日志:

  • Observe the console logs ending with the following on successful execution of your Testcase:

    16:23:50.590 INFO - Found handler: org.openqa.selenium.remote.server.ServicedSession@37ff9771
    16:23:50.590 INFO - Handler thread for session 31a1dcb0-8bed-40fb-acdb-d5be19f03ba2 (firefox): Executing DELETE on /session/31a1dcb0-8bed-40fb-acdb-d5be19f03ba2
     (handler: ServicedSession)
