Wait instructions in automation testing cause test execution to halt for a set amount of time before proceeding to the next phase. WebDriver may now check if one or more web items are there, viewable, enhanced, clickable, and so on.
In Selenium, the synchronisation idea is the best way to wait for a change. To manage a wait, both implicit and explicit waits can be employed. The implicit is a global wait that is applied to all of the page's elements. The implicit wait value is set to 0 by default.
In Selenium WebDriver, there is no overriding of waits, therefore an implicit wait will not override an explicit wait, and vice versa. In reality, if you use both waits, you will be able to use them in frequent cases.
