Selenium-Java: Code crashes if no element is found

Question

I cannot seem to find a solution on this. This line of code seems to crash if it cannot find it. Sometimes it is there and sometimes it is not:

Integer dynamicElement =  myDriver.findElements(By.xpath("//iframe[@title='CAPTCHA']")).size();

I then go on to check the value of my integer, but it crashes when it is not there. How do you get this not to crash?

Answer 1

findElements

findElements() finds all the elements within the current page using the given By mechanism. This method will return as soon as there are more than 0 items in the found collection, or will return an empty list if the timeout is reached.

An example

For a demonstration, searching for the same element on Google Search Home Page perfectly prints 0 as no WebElement is found.

• Code Block:

  driver.get("https://www.google.com/");
  Integer dynamicElement = driver.findElements(By.xpath("//iframe[@title='CAPTCHA']")).size();
  System.out.println(dynamicElement);
  driver.quit();
  

• Console output:

  0
