What does fluent wait perform?

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)

Example

import org.openqa.selenium.By; import org.openqa.selenium.Keys; import org.openqa.selenium.WebDriver; import org.openqa.selenium.WebElement; import org.openqa.selenium.chrome.ChromeDriver; import java.util.concurrent.TimeUnit; import org.openqa.selenium.support.ui.Wait; import org.openqa.selenium.support.ui.FluentWait; public class Fluentwt {    public static void main(String[] args) {       System.setProperty("webdriver.chrome.driver", "C:\Users\ghs6kor\Desktop\Java\chromedriver.exe");       WebDriver driver = new ChromeDriver();       String url = "https://www.tutorialspoint.com/index.htm";       driver.get(url);       //implicit wait with time in seconds applied to each elements       driver.manage().timeouts().implicitlyWait(12, TimeUnit.SECONDS);       //Clicking on Coding Ground link       driver.findElement(By.xpath("//span[text()=’Coding Ground’]")).click();       // fluent wait declaration       Wait<WebDriver> w = new FluentWait<WebDriver>(driver).withTimeout       (Duration.ofSeconds(30))       .pollingEvery(Duration.ofSeconds(3)).ignoring(       NoSuchElementException.class);       WebElement fl = w.until(new Function<WebDriver, WebElement>() {          // customized condition for fluent wait          public WebElement apply(WebDriver driver) {             if (driver.findElement(By.xpath("[//img[@title=’Whiteboard’"))             .isDisplayed()) {                return true;             }else {                return null;             }          }       });       driver.quit();    } }
