Java Selenium远程驱动程序-在InternetExplorerDriver的实现过程中发生NoTouchElementException

目前正在使用selenium远程驱动程序。使用Chrome远程驱动程序执行正常，但不使用IE。IE浏览器在显示NoTouchElementException后启动

我在下面的url中发现了类似的问题，我实现了所有指定的解决方案，但仍然不适用于我。

已启动Selenium网格-集线器使用：机器A:

已启动Selenium网格-节点使用：机器B:

测试脚本中的代码

DesiredCapabilities capabilities = DesiredCapabilities.internetExplorer();
capabilities.setBrowserName("internet explorer");
capabilities.setPlatform(Platform.WINDOWS);             
capabilities.setCapability("ie.ensureCleanSession", true);    
capabilities.setCapability("forceCreateProcessApi", true);
capabilities.setCapability("ignoreProtectedModeSettings", true);
System.setProperty("webdriver.ie.driver", "\\SeleniumDrivers\\IEDriverServer.exe");
WebDriver driver = new RemoteWebDriver(new URL("http://MachineBIPAddress:5566/wd/hub"),capabilities);    

//示例代码

driver.get("www.google.com");
driver.findElement(By.id("gbqfqw")).sendKeys("test");
driver.findElement(By.name("btnG")).click();

执行期间：

我刚刚试过你在IE8、IE10和IE11上的测试。在IE10和IE11上，一切都很好。IE8不会在谷歌页面上运行，因为按钮将隐藏在快速搜索结果下

一种可能的解释是，在您提供的示例中，您使用的是btnG按钮。只有在键入一些文本后，该按钮才可见。也许您需要等到按钮显示出来

您能在您的测试机器上手动执行测试并检查btnG是否确实存在吗

更新：所有机器都是安装了适当版本IE的虚拟机。测试机器设置为通过启动selenium服务器

javaw.exe-Dwebdriver.chrome.driver=chromedriver.exe -Dwebdriver.ie.driver=IEDriverServer.exe-Dphantomjs.binary.path=phantomjs.exe-jar selenium-server-standalone-2.41.0.jar-端口4444

谢谢你的回复

最后，我找到了IE11测试失败的两个原因。现在解决了这些问题

导致此问题的Windows update KB3025390 添加了功能。setCapabilitynativeEvents，false；

忽略ProtectedModeSettings，请在进行任何调试之前删除此项。您好，米兰尼奥，我想您误解了这个问题，我在远程驱动程序中执行时遇到了这个问题。为了进行交叉检查，我已将远程驱动程序更改为web驱动程序，并在本地使用IE浏览器脚本进行传递，没有任何问题。当我使用远程驱动程序执行时，只会出现问题。Hi@chanduk，我刚刚更新了通过远程webdriver运行的测试，请参见上文-测试单击SigningInInternetExplorerThroughRemoteDriver，它将通过IE8和IE10。远程计算机上有什么版本的IE？你能看到那台远程机器的屏幕吗？你们确定那个按钮真的在那个里吗？嗨@milano，我使用的是IE11，远程驱动程序配置使用。我能看到遥控器驱动程序的屏幕。并且driver.get语句已成功执行。我举的谷歌网站为例。嗨@chanduk，我完全改变了答案，因为这个问题不再与CSSSelector相关。我刚刚用IE11和IE10运行了测试，它们通过了google页面。它会在IE8上失败，因为谷歌页面在IE8上看起来不同。嗨，米兰，你是在做本地执行还是远程执行？我是说另一台不同的机器。对于IE，您所做的设置是什么。您还可以指定用于启动节点的连接字符串。我对您的代码有一个疑问，您没有指定要执行的节点。

DesiredCapabilities capabilities = DesiredCapabilities.internetExplorer();
capabilities.setBrowserName("internet explorer");
capabilities.setPlatform(Platform.WINDOWS);             
capabilities.setCapability("ie.ensureCleanSession", true);    
capabilities.setCapability("forceCreateProcessApi", true);
capabilities.setCapability("ignoreProtectedModeSettings", true);
System.setProperty("webdriver.ie.driver", "\\SeleniumDrivers\\IEDriverServer.exe");
WebDriver driver = new RemoteWebDriver(new URL("http://MachineBIPAddress:5566/wd/hub"),capabilities);    

driver.get("www.google.com");
driver.findElement(By.id("gbqfqw")).sendKeys("test");
driver.findElement(By.name("btnG")).click();
