title: Check element existence with WebDriver findElements().isEmpty method
body: <p>I need to check if some element exists on the page or not.<br>
  I already saw this <a href="https://stackoverflow.com/questions/6521270/webdriver-check-if-an-element-exists">WebDriver: check if an element exists?</a> issue but I'm wondering why not simply apply <code>findElements().isEmpty</code> method?<br>
  I thought it would do the same work.  </p>
  
  <p><strong>UPD</strong> Now I see <code>findElements().isEmpty</code> works perfect so I'm just wondering why to look for other, much complex ways, while there is a straightforward method for that?  </p>
