NoSuchElementException can't be thrown

I'm trying to use an element for testing and I want to continue the test if the element even couldn't be found.

I used NoSuchElementException for this part of my codes.

Here is what I've tried before:

try {
    WebElement site_width_full_width = wait.until( 
            ExpectedConditions.visibilityOfElementLocated(
            By.cssSelector("label[for=site_width-full_width]")));
    site_width_full_width.click();

    Thread.sleep(1000);
    System.out.println("FullWidth Label Found!");

} catch (NoSuchElementException e) {
    System.out.println("FullWidth Label not found!");
    System.out.println(e);
}

But when the element isn't available it can't be thrown into the NoSuchElementException and all test breaks and fails.

What's the solution and how could I continue the test when the element isn't available.

Thanks in advance.

Webdriver already provide the way to deal this problem in much simpler way. you can use following way

 WebDriverWait wait= new WebDriverWait(driver, TimeSpan.FromSeconds(120));
    wait.IgnoreExceptionTypes(typeof(NoSuchElementException), typeof(ElementNotVisibleException));

 WebElement site_width_full_width = wait.until( 
            ExpectedConditions.visibilityOfElementLocated(
            By.cssSelector("label[for=site_width-full_width]")));
    site_width_full_width.click();

    Thread.sleep(1000);
    System.out.println("FullWidth Label Found!");

Note : You can add all types of exception need to be ignored.

You are catching a NoSuchElementException, but an explicit wait throws a TimeoutException if nothing is found. To get what you have working you should modify your code to do the following:

    try {
        WebElement site_width_full_width = wait.until(
                ExpectedConditions.visibilityOfElementLocated(
                        By.cssSelector("label[for=site_width-full_width]")
                ));
        site_width_full_width.click();
        System.out.println("FullWidth Label Found!");
    } catch (NoSuchElementException | TimeoutException e) {
        System.out.println("FullWidth Label not found!");
        System.out.println(e);
    }

However using Try/Catch for execution flow is generally a code anti-pattern. You would be much better off doing something like this:

    List<WebElement> site_width_full_width = 
            driver.findElements(By.cssSelector("label[for=site_width-full_width]"));
    if (site_width_full_width.size() > 0) {
        System.out.println("FullWidth Label Found!");
        site_width_full_width.get(0).click();
    } else {
        System.out.println("FullWidth Label not found!");
    }

You might be getting the exception of a different derived class type. You can catch it using the parent class 'Exception' and then further drill down the exact exception type.

try using;

try
{
            WebElement site_width_full_width = wait.until(
                    ExpectedConditions.visibilityOfElementLocated(
                    By.cssSelector("label[for=site_width-full_width]")));
            site_width_full_width.click();

            Thread.sleep(1000);
            System.out.println("FullWidth Label Found!");

        }
        catch (Exception e)
        {
            if (e instanceof NoSuchElementException)
            {
                System.out.println("FullWidth Label not found!");
                System.out.println(e);
            }
            else
            {
                System.out.println("Unexpected exception!");
                System.out.println(e);
            }
        }

Hope this helps.

You can try with its parent classes like Throwable or Exception in catch block. In my case, I am Throwable in catch block which works as expected
