Thread is a class in JAVA and sleep() is the static method inside Thread class.Syntax - Thread.sleep(2000); where 2000 is the ms.But the disadvantage is that suppose we have mentioned wait for 5 sec whereas the element become visible in 2 ms only, so we have waited unnecessarily for 3 more ms. Create a class called CustomFluent2. The maximum amount of time (15 seconds) to wait for a condition and the frequency (2 seconds) to check the success or failure of a specified condition. The Fluent Wait in Selenium is used to define maximum time for the web driver to wait for a condition, as well as the frequency with which we want to check the condition before throwing an " ElementNotVisibleException " exception. When executing selenium automation tests, we use waits to make our tests reliable and robust. You can see that the function made four attempts to check the color of the button. Also useful for verifying property of the element such as visibilityOfElementLocated, elementToBeClickable,elementToBeSelected.

Fluent Wait in Selenium marks the maximum amount of time for Selenium WebDriver to wait for a certain condition (web element) becomes visible. It allows us to ignore the occurrences of any exceptions during polling period. It will return false if the condition fails. Alternatively, we can derive this info from the below syntax: Itsignifies that the first input parameter is the argument to the apply() method and the second indicates its return type. In above syntax we have given 30 seconds timeouts and 5 seconds polling time. This indicates that our FluentWait is indeed working fine. fw.until(ExpectedConditions.elementToBeClickable(By.linkText("LIFETIME MEMBERSHIP TO ALL LIVE TRAININGS"))).click();; fw.until(ExpectedConditions.urlContains("lifetime-membership-club")); Your email address will not be published. timeoutException is a protected method of the FluentWait class; we have to override this method to raise our own messages.
