The default time value for the implicit wait is zero. However, the syntax for ignoring exceptions while using Fluent Wait is as follows: In this tutorial, we understood how some web elements could take more time to load than others. We are explicitly making the execution of selenium code to wait, for a certain condition to occur before, proceeding further in the code. If the element is not located within that time interval, then WebDriver will throw an "ElementNotVisibleException".

So whenever we load a page inside the browser it will wait for 40 seconds before throwing us the TimeoutException. Since some elements might have been created with the help of ajax or front-end frameworks, it takes some time for them to load, but since they havent been loaded yet, running tests on them fails. Selenium Wait strategies are a very critical topic in selenium test automation.In order to have non-flaky tests, we have to know explicit wait, implicit wait, fluent wait strategies. One of the most important factors in Selenium C# is the ability to use Wait commands to reduce the flakiness of our tests.
