Fluent wait is a dynamic wait which makes the driver pause for a condition which is checked at a frequency before throwing an exception. The element is searched in DOM not constantly but at a regular interval of time.
For example, if the wait is for 5 seconds, FluentWait monitors the DOM at regular intervals (defined by polling during time). In FluentWait, customized wait methods based on conditions need to be built.
Syntax −
Wait<WebDriver> w = new FluentWait< WebDriver >(driver) .withTimeout (10, SECONDS) .pollingEvery (2, SECONDS) .ignoring (NoSuchElementException.class)
