Selenium Catch exception

Question

I'm launching a selenium test. For some user you don't have the same number of page. That's why I need to implement a try catch in my code but sadly every time he try and the element is not there he stop the program. Giving NoSuchElementException while I put this try catch. I try to put before each click if the element displayd before but the same error show up.

If someone can help me that's will be really nice!

try {
        driver.manage().timeouts().pageLoadTimeout(10, TimeUnit.SECONDS);
        driver.findElement(By.xpath("//input[@type='radio' and @value='true']")).click();
        sleep();

        driver.findElement(By.xpath("//input[@type='submit' and @value='>> valider <<']")).click();
        sleep();
 } catch (org.openqa.selenium.NoSuchElementException e) {
            e.printStackTrace();
 }

You are printing e.printStackTrace(); in catch block which print the Stacktracerepalce this with your code like System.out.println("Element is not found"); or some code — iamsankalp89

you need to first check if the element is there or not and then click that element, You can create following method :

public boolean isElementPresent(WebDriver driver, By elem) {
        try {
            driver.findElement(elem);
            return true;
        }catch(NoSuchElementException e) {
            return false;
        }
    }

This method returns 'true' if element is present.

Then you can call this method to check if element is present before clicking the element as following:

try {
        driver.manage().timeouts().pageLoadTimeout(10, TimeUnit.SECONDS);
        if(isElementPresent(driver, By.xpath("//input[@type='radio' and @value='true']")){
            driver.findElement(By.xpath("//input[@type='radio' and @value='true']")).click();
        }
        sleep();

        driver.findElement(By.xpath("//input[@type='submit' and @value='>> valider <<']")).click();
        sleep();
 } catch (org.openqa.selenium.NoSuchElementException e) {
            e.printStackTrace();
 }
