Question

我正在尝试设置远程webdriver以在远程计算机上运行我的测试，因为我的应用程序已部署到我的localhost。使用Selenium RC我使用主机地址来运行这些测试，它运行良好;但是我在使用远程webdriver设置基类时遇到了麻烦。我已经尝试了以下代码，但它没有奏效。顺便说一句，我有selenium测试，我正在迁移到远程webdriver。我试过webdriver工作正常，但无法设置远程webdriver进行远程执行。任何帮助将不胜感激。

public static  String base_url = "http://localhost:8084";     
Proxy proxy = new Proxy();     
proxy.setProxyAutoconfigUrl(base_url);
DesiredCapabilities capabilities = DesiredCapabilities.internetExplorer();
capabilities.setCapability(CapabilityType.PROXY, proxy);
RemoteWebDriver driver = new RemoteWebDriver(capabilities);
selenium = new WebDriverBackedSelenium(driver, base_url);

示例网格2代码适用于Firefox但在IE9上不起作用

String hubURL = "http://myip:4444/wd/hub";
DesiredCapabilities capability = DesiredCapabilities.internetExplorer();
//capability.setBrowserName("internet explorer");
//capability.setPlatform("WINDOWS");
//capability.setVersion("9.0.4");
WebDriver driver = new RemoteWebDriver(new URL(hubURL), capability);
driver.get("http://www.google.com");
WebElement element = driver.findElement(By.name("q"));
element.sendKeys("Cheese!");
element.submit();
driver.quit();

虽然我从IE9命令模式中指定了IE，但是当它是IE9时我才收到错误：

Answer 1

您必须安装Selenium Server（Hub）并将远程WebDriver注册到它。然后，您的客户将与Hub交谈，Hub将找到匹配的WebDriver来执行您的测试。

您可以查看here了解详情。

Answer 2

这个问题来自我，因为我正在使用selenium-server-standalone-2.32.0运行服务器，并且客户端使用selenium-server-standalone-2.37.0注册。当我同时制作了两个selenium- server-standalone-2.32.0并运行然后一切正常

Answer 3

默认情况下，InternetExplorerDriver侦听端口＆＃34; 5555＆＃34;。改变你的huburl以匹配它。你可以在cmd框窗口上查看确认。

Answer 4

这就是我摆脱错误的方法：

WebDriverException：转发新会话时出错无法找到： {platform = WINDOWS，ensureCleanSession = true，browserName = internet explorer，version = 11}

在nodeconfig.json中，版本必须是字符串，而不是整数。

因此，不要使用"version": 11使用"version": "11"（请注意双引号）。

RemoteWebDriver的工作nodecondig.json文件的完整示例：

{
  "capabilities":
  [
    {
      "platform": "WIN8_1",
      "browserName": "internet explorer",
      "maxInstances": 1,
      "seleniumProtocol": "WebDriver"
      "version": "11"
    }
    ,{
      "platform": "WIN7",
      "browserName": "chrome",
      "maxInstances": 4,
      "seleniumProtocol": "WebDriver"
      "version": "40"
    }
    ,{
      "platform": "LINUX",
      "browserName": "firefox",
      "maxInstances": 4,
      "seleniumProtocol": "WebDriver"
      "version": "33"
    }
  ],
  "configuration":
  {
    "proxy": "org.openqa.grid.selenium.proxy.DefaultRemoteProxy",
    "maxSession": 3,
    "port": 5555,
    "host": ip,
    "register": true,
    "registerCycle": 5000,
    "hubPort": 4444,
    "hubHost": {your-ip-address}
  }
}

Answer 5

首先，您需要创建HubNode（服务器）并使用Java从命令行/提示符启动HubNode（服务器）：-jar selenium-server-standalone-2.44.0.jar -role hub
然后使用集线器IPAddress或名称将节点/客户端绑定到此集线器，并使用任何端口号> 1024。例如，对于节点机器：Java -jar selenium-server-standalone-2.44.0.jar -role webdriver -hub http://HubmachineIPAddress:4444/grid/register -port 5566

还有一件事是，每当我们使用Internet Explore或Google Chrome时，我们都需要设置：System.setProperty("webdriver.ie.driver",path);

设置远程Webdriver以使用Java在远程计算机中运行测试
