Once this time is determined, it remains for the entire driver session. The default value of time that can be set using Implicit wait is zero. Sleep () is used when testing or creating a framework. It means if we set sleep timeout as 5 seconds, thread will wait for 5 seconds completely (If not interrupted). The Implicit wait is used to set the maximum time for the driver object. These features are very useful in implementation of the test automation for the applications that have AJAX calls and other asynchronous request model for dynamic loading of the web elements on the web page under test.
