fluent wait in selenium

//required import WebDriver driver = new ChromeDriver(); // Timeout in seconds WebDriverWait wait = new WebDriverWait(driver, 15); //Three most common explicit waits //waits until the element is visible and can be clicked wait.until(ExpectedConditions.elementToBeClickable(By.id("button1"))); //waits until the element is visible on the page somewhere i.e. pixels > 0 wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("text_box1"))); //waits until the element is removed from the page //This one is helpful when moving from one page to another wait.until(ExpectedConditions.invisibilityOfElementLocated(By.id("text_box1"))); //implicit wait will wait a set time, similar to Thread.sleep(); driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS); //There is also a FluentWait, but I am unfamiliar with it

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<WebDriver> wait = new FluentWait<WebDriver>(driver) .withTimeout(30, TimeUnit.SECONDS) .pollingEvery(3, TimeUnit.SECONDS) .ignoring(NoSuchElementException.class); FluentWait uses two parameters mainly – timeout value and polling frequency. and ignoring...

waits in selenium

- Synchronization is making sure our driver
  and browser are on the same page.
- Since selenium browser driver is a lot
  faster compared to the browsers , we use
  different types of waits to make sure
  selenium is synchronized with browsers.

There are 3 wait types to handle synchronization
issue from selenium;

1- Implicit Wait
Everytime we are trying to locate a webelement
is triggered. By default wait time is 0 second.
If we set the time to 10 seconds, and our driver
not able to find element, it will count for
given time. If element findst the webelement
it doesn't throw an exception.

2- Explicit Wait & 3- Fluent Wait
Both explicit and fluent wait is waiting for
explicit condition to happen
Like:
-elementIsDisplayed
-titleIs()
-visibilityOf
-elementToBeClickable
I use explicit wait in my framework

**THREAD.SLEEP
There is also thread.sleep comes from java library.
I always avoid to use it since it makes my
automation framework slower and heavier.
Thread.sleep basically holds the whole execution
for given time without any condition
