Question

I want to wait until a js script return true, the code I am using is not compiling and throwing error

is not abstract and does not override abstract method apply(Object) in Function

here is the code

WebDriverWait wait = new WebDriverWait(driver, 10);
        boolean isFound = wait.until(new ExpectedCondition(){ //here ERROR
            public Boolean apply(WebDriver d){
                JavascriptExecutor js = (JavascriptExecutor) d;
                return (Boolean) js.executeScript("return true");
            }
        });

I tried to copy code from

Answer 1

instead of

        public Boolean apply(WebDriver d){
            JavascriptExecutor js = (JavascriptExecutor) d;
            return (Boolean) js.executeScript("return true");
        }

try

        public Boolean apply(Object d){
            JavascriptExecutor js = (JavascriptExecutor) d;
            return (Boolean) js.executeScript("return true");
        }

The Function class/interface expects a method with this signature in its subclasses that you create.

If there’s a raw types warning, perhaps new ExpectedCondition<WebDriver>(){ ... is what you’re expected to do?
