Selenium Remote Driver - NoSuchElementException is occurred during implementation of InternetExplorerDriver

问题

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.

回答1:

I've just tried your test on IE8, IE10 & IE11. On IE10 & IE11 everything works perfectly fine. IE8 will not work on google page because the buttons will be hidden under quick search results.

One possible explanation would be that in the example you have provided you are using "btnG" button. That button is made visible only after you type some text. Maybe you need to wait until button is displayed.

Can you do the test manually on your test machine and check if the "btnG" is actually there?

Update : All machines are VMs with appropriate version of IE installed. Test Machines are setup to start selenium server through

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 -port 4444

[TestCase("IE8", "http://xxx-xxx-tuai04:4444/wd/hub")]
[TestCase("IE10", "http://xxx-xxx-tuai01:4444/wd/hub")]
[TestCase("IE11", "http://xxx-xxx-tuai02:4444/wd/hub")]
public void ClickSignInInInternetExplorerThroughRemoteDriver(string version, string url)
{
    using (var driver = new RemoteWebDriver(new Uri(url), DesiredCapabilities.InternetExplorer()))
    {

        driver.Navigate().GoToUrl("https://www.google.com/?gws_rd=cr,ssl&fg=1");
        driver.Manage().Timeouts().ImplicitlyWait(TimeSpan.FromSeconds(5));

        var element = driver.FindElementById("gbqfqw");
        element.SendKeys("test");

        var btn = driver.FindElementByName("btnG");
        btn.Click();
    }

}
