Question

我遇到了Selenium Remote Server作为网格的问题。我正在测试应用程序和计算机，我启动服务器和4个节点，一个用于FireFox，一个用于Chrome，另一个用于Internet Explorer，最后一个用于HtmlUnit。

当我选择FireFox或HtmlUnit时没有问题。但是对于Chrome和IE，它取决于我们首先启动的是哪一个。我们首先启动的节点是运行的节点。

我在C＃中使用selenium RemoteWebDriver。代码是：

if (browserId == 1)
  webDriver = new RemoteWebDriver(new Uri(Properties.Settings.Default.HubUri),
                                          DesiredCapabilities.HtmlUnit());
else if (browserId == 2)
  webDriver = new RemoteWebDriver(new Uri(Properties.Settings.Default.HubUri), 
                                          DesiredCapabilities.Firefox());
else if (browserId == 3)
  webDriver = new RemoteWebDriver(new Uri(Properties.Settings.Default.HubUri), 
                                  DesiredCapabilities.InternetExplorer());
else if (browserId == 4)
  webDriver = new RemoteWebDriver(new Uri(Properties.Settings.Default.HubUri), 
                                  DesiredCapabilities.Chrome());

我使用以下命令行启动了服务器：

java -jar selenium-server-standalone-2.38.0.jar -role hub

节点：

java -jar selenium-server-standalone-2.38.0.jar -Dwebdriver.ie.driver="C:\Utilities\Grid\IEdriverServer.exe" -role node -hub http://"localhost":4444/grid/register -port 5559
java -jar selenium-server-standalone-2.38.0.jar -role node -hub http://"localhost":4444/grid/register -port 5557
java -jar selenium-server-standalone-2.38.0.jar -Dwebdriver.chrome.driver="C:\Utilities\Grid\chromedriver.exe" -role node -hub http://"localhost":4444/grid/register -port 30000
java -jar selenium-server-standalone-2.38.0.jar -role node -hub http://"localhost":4444/grid/register -browser browserName=htmlunit -port 5558

我想知道一切是否正确以及是否可以在同一台PC上运行这些节点。

我正在使用Firefox，Intermet Explorer，Chrome和HtmlUnit。与Chrome和Internet Explorer存在冲突。

感谢您的帮助。

我不明白为什么你需要在同一台PC上运行4个不同的节点。如果您在该PC上运行一个网格节点，它将支持运行您需要的所有实例。一个Grid节点可以执行多种类型的多个浏览器。你有什么理由不这么想吗？只有我能想到的另一个原因是你是否试图在不同的Linux xvfb会话中运行这些独立的浏览器？

Selenium Grid：同一台PC中的2个节点
