Hi Sandeep,
I have tried as your suggestion below :
wait.until( ExpectedConditions.visibilityOfElementLocated( Checkout_Process_Page.Checkout_Page1( driver)));
I am getting error message"The method visibilityOfElementLocated(By) in the type ExpectedConditions is not applicable for the arguments (WebElement)".
I think i can not use WebElement with wait.until( ExpectedConditions.visibilityOfElementLocated function, Only we can use only string Xpath.
Please suggest me for this
