How to use lamba in Fluent Wait

[sunny sachdeva]

HI ,

I was using fluent waits and then upgraded webdriver version to 3.3.1 and found that lambdas has been introduced and old way of Fluent wait are no longer working

Can anyone help me in converting below fluent wait to lambda

public void waitForWebElementFluentlyPredicate(){ 
     new FluentWait<WebElement>(countdown). 
       withTimeout(10, TimeUnit.SECONDS). 
       pollingEvery(100,TimeUnit.MILLISECONDS).
       until(new Predicate<WebElement>() { 
        @Override 
        public boolean apply(WebElement element) 
         { return element.getText().endsWith("04"); 
         } 
       } );
 }

Thanks

Sunny

If you are using an IDE such as IntelliJ, it should help you get this converted no ?

This is what I got : 

until ((Predicate<WebElement>) element -> element.getText().endsWith("04");

Thanks Krishnan . In latest version of webdriver, the below code wont work since as per doc [https://raw.githubusercontent.com/SeleniumHQ/selenium/master/java/CHANGELOG]

Remove deprecated `FluentWait.until(Predicate<?>)` method. This
  should make lambdas work properly with Wait instances now.

Hence I used the below code 

wait.until((driver)->driver.findElement(by).getText().endsWith("04"));

Thanks

Update your version of guava to version 21 or later. That'll fix the problem you're seeing.

Thanks Simon this helped. But i was assuming guava version would be part of maven selenium-java. Am i missing anything?

Not really. If you only have selenium as a dependency, it'll pull in the right version transitively. Otherwise, you'll be at the mercy of Maven's dependency resolution mechanisms.
