Fluent Wait in Selenium WebDriver

When we use selenium “WebDriverWait” and “ExpectedCondition”, webdriver continuously checks for the element and which may reduce the performance. Solution for this is configuring to make webdriver to check for element at regular interval of time instead of checking continuously. This regular interval of time is called as fluent time.

Syntax to configure fluent wait

Example

Before Selenium 3.11

Wait<WebDriver> wait = new FluentWait(WebDriverInstance)

                .withTimeout(duration, unit)

                .pollingEvery(duration, unit)

                .ignoring(Exception.class);

WebDriver driver = new ChromeDriver();

Wait<WebDriver> wait = new FluentWait(driver)

                .withTimeout(10, TimeUnit.SECONDS)

                .pollingEvery(2, TimeUnit.SECONDS)

                .ignoring(Exception.class);

Selenium 3.11 and above

Wait<WebDriver> wait = new FluentWait(driver)

                .withTimeout(DurationInstance)

                .pollingEvery(DurationInstance)

                .ignoring(Exception.class);

WebDriver driver = new ChromeDriver();

Wait<WebDriver> wait = new FluentWait(driver)

                .withTimeout(Duration.ofSeconds(15))

                .pollingEvery(Duration.ofSeconds(3))

                .ignoring(Exception.class);
