Selenium Remote Driver - 执行InternetExplorerDriver时发生NoSuchElementException异常 [英] Selenium Remote Driver - NoSuchElementException is occurred during implementation of InternetExplorerDriver

问题描述

目前使用selenium远程驱动程序。 Chrome的远程驱动程序执行正常，但无法使用IE。 IE浏览器启动后，NoSuchElementException显示

类似的问题我发现在下面url，我实现了所有指定的解决方案仍然不适合我。
在Selenium WebDriver中实现InternetExplorerDriver期间发生NoSuchElementException

使用以下功能启动Selenium网格 - 集线器：（机器A）：

  java -jar selenium-server-standalone-2.44.0.jar -role hub 
  

使用：（机器B）启动Selenium网格节点：

  java -jar selenium-server-standalone-2.44.0.jar -role webdriver -hub http：//xx.x.xx.xx：4444 / grid / register -port 5566 -browser browserName =internet explorer，version = 8.0，platform = WINDOWS -Dwebdriver.ie.driver = \\SeleniumDrivers\IEDriverServer.exe 
  

代码测试脚本（Eclipse）

  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驱动程序=新的RemoteWebDriver（新URL（http：// MachineBIPAddress：5566 / wd / hub），功能）; 
  

//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：

  IE浏览器在机器B中启动，然后显示错误org.openqa.selenium.NoSuchElementException：。

解决方案

感谢您的回复

最后我发现有两个原因，为什么测试在IE 11失败。现在解决他们

1. Windows更新 KB3025390 导致问题


2. 添加了capabilities.setCapability（nativeEvents，false）;

WebDriver测试不在IE11上运行

Currently working with selenium remote driver. execution is working fine with Chrome remote driver but not working with IE. IE browser is launched after that NoSuchElementException displayed

similar issue I found at below url, I implemented all the specified solutions still not working for me. NoSuchElementException is occurred during implementation of InternetExplorerDriver in Selenium WebDriver

Launched Selenium grid - hub using: (Machine A) :

java -jar selenium-server-standalone-2.44.0.jar -role hub  

Launched Selenium grid - node using: (Machine B) :

java -jar selenium-server-standalone-2.44.0.jar -role webdriver -hub http://xx.x.xx.xx:4444/grid/register -port 5566 -browser browserName="internet explorer",version=8.0,platform=WINDOWS -Dwebdriver.ie.driver=\\SeleniumDrivers\IEDriverServer.exe

Code in the test script.(Eclipse)

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);    

//example code.

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

During the Execution:

IE browser is launched in Machine B and then error "org.openqa.selenium.NoSuchElementException:" displayed.

解决方案

Thank you for the responses.

finally i found with two reasons why tests are failed in IE 11. Now resolved them

1. Windows update KB3025390 causing the issue
2. Added capabilities.setCapability("nativeEvents",false);

WebDriver test not running on IE11
