Selenium WebDriver - Test if element is present

Question

is there a way how to test if an element is present? Any findElement method would end in an exception, but that is not what I want, because it can be that an element is not present and that is okay, that is not a fail of the test, so an exception can not be the solution.

I've found this post: Selenium c# Webdriver: Wait Until Element is Present But this is for C# and I am not very good at it. Can anyone translate the code into Java? I am sorry guys, I tried it out in Eclipse but I don't get it right into Java code.

This is the code:

public static class WebDriverExtensions{
    public static IWebElement FindElement(this IWebDriver driver, By by, int timeoutInSeconds){

        if (timeoutInSeconds > 0){
            var wait = new WebDriverWait(driver, TimeSpan.FromSeconds(timeoutInSeconds));
            return wait.Until(drv => drv.FindElement(by));
        }

        return driver.FindElement(by);
    }
}

Answer 1

I found that this works for Java:

WebDriverWait waiter = new WebDriverWait(driver, 5000);
waiter.until( ExpectedConditions.presenceOfElementLocated(by) );
driver.FindElement(by);

Answer 2

public static WebElement FindElement(WebDriver driver, By by, int timeoutInSeconds)
{
    WebDriverWait wait = new WebDriverWait(driver, timeoutInSeconds);
    wait.until( ExpectedConditions.presenceOfElementLocated(by) ); //throws a timeout exception if element not present after waiting <timeoutInSeconds> seconds
    return driver.findElement(by);
}

Answer 3

public boolean isElementFound( String text) {
        try{

            WebElement webElement = appiumDriver.findElement(By.xpath(text));
            System.out.println("isElementFound : true :"+text + "true");

        }catch(NoSuchElementException e){
            System.out.println("isElementFound : false :"+text);
            return false;
        }
        return true;
    }

Answer 4

Write the following function/methos using Java:

protected boolean isElementPresent(By by){
        try{
            driver.findElement(by);
            return true;
        }
        catch(NoSuchElementException e){
            return false;
        }
    }

Call the method with appropriate parameter during assertion.

Answer 5

This works for me:

 if(!driver.findElements(By.xpath("//*[@id='submit']")).isEmpty()){
    //THEN CLICK ON THE SUBMIT BUTTON
}else{
    //DO SOMETHING ELSE AS SUBMIT BUTTON IS NOT THERE
}

Answer 6

Try this: Call this method and pass 3 arguments:

1. WebDriver variable. // assuming driver_variable as driver.
2. The element which you are going to check. Should provide from By method. // ex: By.id("id")
3. Time limit in seconds.

Example: waitForElementPresent(driver, By.id("id"), 10 );

public static WebElement waitForElementPresent(WebDriver driver, final By by, int timeOutInSeconds) {

        WebElement element; 

        try{
            driver.manage().timeouts().implicitlyWait(0, TimeUnit.SECONDS); //nullify implicitlyWait() 

            WebDriverWait wait = new WebDriverWait(driver, timeOutInSeconds); 
            element = wait.until(ExpectedConditions.presenceOfElementLocated(by));

            driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS); //reset implicitlyWait
            return element; //return the element
        } catch (Exception e) {
            e.printStackTrace();
        } 
        return null; 
    }
