Lets put a wrong locator so that it would not be able to locate element within timeout. Crisp & Clear Understanding of Implicit Wait!! There are other disadvantages of using implicit waits as well. For example in the above . Once the time is elapsed, we move on to the next test. If the element cannot be found it does not make any sense to go on. In the above example, I used the Facebook sign-up credentials and located them using name locators. In this code, Selenium WebDriver will wait for 30 seconds before throwing a TimeoutException.
