FluentWait code example

Example 1: what is fluent wait selenium

FluentWait can define the maximum amount
of time to wait for a specific condition
and frequency/interval with which to
check the condition before throwing an 
“ElementNotVisibleException” exception.

To say in effortless manner, it tries
to find the web element repeatedly at 
regular intervals of time until the
timeout or till the object gets found.

We use FluentWait commands mainly when
we have web elements which sometimes 
visible in few seconds and some times
take more time than usual. Mainly in
Ajax applications. We could set the
default polling period based on our
requirement. We could ignore any
exception while polling an element.

Wait wait = new FluentWait(driver)							
	.withTimeout(30, TimeUnit.SECONDS) 			
	.pollingEvery(3, TimeUnit.SECONDS) 			
	.ignoring(NoSuchElementException.class);

FluentWait uses two parameters mainly – 
timeout value and polling frequency. and ignoring...

Example 2: implicit wait vs explicit wait

In Implicit wait, if WebDriver is not able to
locate an element, it will wait for a specified
amount of time for the element to appear, 
before throwing an exception.

Explicit wait is a type of wait , which is used to
stop the execution till a specific condition is true;
We use WebDriverWait and ExpectedCondition classes of
Selenium web driver to implement explicit wait.
Implicit wait is general, explicit wait is applied
for a particular instance only.



WebDriverWait wait = new WebDriverWait(driver, 10);
wait.until(ExpectedConditions.elementToBeClickable(txtFirstname));
