Selenium: NoSuchElementException in Internet Explorer
I am trying to pipe Selenium script for internal Webapp from Selenium IDE to Selenium Grid using RemoteWebDrivers in Java.
The scripts work fine with Chrome and Firefox, but not Internet Explorer. Every time I try to find an element on the page, I only get a NoSuchElementException (the page itself loads just fine).
Sample code that demonstrates the same behavior using the Wikipedia page:
public class Wikipedia_test_IE {
private WebDriver driver = null;
private String baseUrl = null;
private boolean acceptNextAlert = true;
private StringBuffer verificationErrors = new StringBuffer();
@Before
public void setUp() throws Exception {
// DesiredCapabilities cap = DesiredCapabilities.firefox();
DesiredCapabilities cap = DesiredCapabilities.internetExplorer();
cap.setCapability(CapabilityType.VERSION, "9");
driver = new RemoteWebDriver (new URL("http://192.168.1.230:4444/wd/hub"), cap);
baseUrl = "https://en.wikipedia.org/wiki/Rosetta_%28spacecraft%29";
driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
}
@Test
public void testAKTargobankTestfall1KN() throws Exception {
driver.get(baseUrl);
driver.findElement(By.linkText("space probe")).submit();
}
}
I've tried using findElement (By.Id) and findElement (By.cssSelector) - no effect. Enabling a delay between pageload and selection also has no effect, nor does it use click instead of submit.
I've enabled IE driver debug logging, but Output doesn't help me figure out what the problem is - hopefully someone else can.

Thanks for the help. To answer some of the Questions noted above that I should have included in the original post:
-Yes, this is really IE 9 - I have already enabled protected mode in all security zones -including click instead of submit did not change (originally)
It just so happened that the virtual machine running the Selenium node was applying security updates overnight, and that included one for IE.
At first I got a different error message than before - IE was unable to find an open browser window, and the windows were not closed either. All security settings have been updated to reset.
After re-enabling protected mode, everything works. As Richard noticed what I did , the find element needs to be changed to .click () instead of .submit ().
So now everything is working and I have no idea why. Thanks again!

I also had an error in tests that worked fine on FF, but not on IE.
I can offer you:
- Check IE Protected Mode settings.
- To disable native events in IE driver.
- Use JavaScript in these specific cases (worst in my point of view).
This is a known issue with the IE driver.

Try using InternetExplorerDriver
instead RemoteWebDriver
, generally it shouldn't matter, but with IE everything is possible .- <- p>
I'm having similar problems and I get the following code that works for me:
@Before
public void setUp() {
//... some irrelevant Code ...
System.setProperty("webdriver.ie.driver", "Path to IEDriver.exe");
InternetExplorerDriver driver = new InternetExplorerDriver();
//... some irrelevant Code ...
}

You can write your code like this:
while(true) {
try {
driver.findElement(By.linkText("space probe")).submit();
break;
} catch (Exception e) {
continue;
}
}
I am writing my code so that the thread runs until it succeeds. When used, the implicitlyWait
browser will only wait for the maximum of this time. But it may happen that the browser page has finished loading, but the desired part is loaded by the ajax call. In this case, your program throws an error.
