How to resolve NoSuchElementException in Selenium with java?

Question

CODE:

driver.findElement(By.name("USER")).sendKeys("XYZ");
driver.findElement(By.name("PASSWORD")).sendKeys("abc");

I have tried various ways not just name but by xpath, css selectors but every time the error remained same. While inspecting the elements the below is the result. As seen in other answers it is not in iframe. I have also tried putting a wait statement but no luck.

HTML:

<input class="news" name="USER" value="" size="13" style="width:100%;">
<input class="news" name="PASSWORD" value="" size="13" style="width:100%;" 
type="password">

Exception:

org.openqa.selenium.NoSuchElementException: no such element: Unable to 
locate element: {"method":"name","selector":"USER"}

• Syrus: I had the same problem, sometimes it happen if the page is not properly at the time of searching the element. Try this PageFactory.initElements(driver, "class name".class); Refer this page. It will give you a proper idea toolsqa.com/selenium-webdriver/…
• Bill Hileman: Can you share the URL?
• Vel Guru: use explicit wait statement and try
• Satadip Ghosh: @joe I have tried that way as well but that too isn't working.
• Syrus: its better if you have given the code. I had same problem. Have tried using "PageFactory.initElements"? Take this for an example GoogleSearchPage page = PageFactory.initElements(driver, GoogleSearchPage.class)

Answer 1

There may be several reasons.

1. Page not correctly loaded at the time. To resolve this driver.manage().timeouts().pageLoadTimeout(30, TimeUnit.SECONDS); you can add page load timeout.

2. Element is not actually visible in screen and you need to scroll down or scroll up to that element

   public void scrollDown(){
    JavascriptExecutor js = (JavascriptExecutor) driver;
    js.executeScript("window.scrollBy(0,250)", "");
   }
   

3. Another solution is Add time to wait until element visible

   public WebElement waitUntilElementVisible(WebDriver driver, WebElement element, int delay) {
    try{
    WebDriverWait wait = new WebDriverWait(driver, delay);
    return wait.until(ExpectedConditions.visibilityOf(element));
    }catch (NoSuchElementException e){
    throw new RuntimeException("Web element not visible within given time" + element +" Time "+ delay);
    }
   }
   

Answer 2

In .Net ISearchContext.FindElement() throws NoSuchElementException. Based on the official Selenium documentation I speculate that in Java it does not throw exception or WebDriverWait.Until knows how to handle it.

WebDriverWait.IgnoreExceptionTypes(typeof(NoSuchElementException)); would help but it does not work.

Solved with static helper method:

using OpenQA.Selenium;
namespace Blah
{
 public static class SearchContextHelper
 {
 public static IWebElement TryFindElement(this ISearchContext searchContext, By by)
 {
 try { return searchContext.FindElement(by); }
 catch (NoSuchElementException) { return null; }
 }
 }
}

Answer 3

you can try : selenium.waitForPageToLoad(PAGE_TO_LOAD_TIMEOUT);

Answer 4

If page will be not loaded properly then it might be this kind of error will be occur Please try with this:

WebElement username=driver.findelement(By.name("USER"));
Thread.sleep(2000);
username.sendkeys("test");
WebElement username=driver.findelement(By.name("PASSWORD"));
Thread.sleep(2000);
username.sendkeys("test");
