How to do scroll action till the particular element is present in appium ?

I am currently working on appium for automating WhatsApp mobile application. I needed one method which would perform the ‘scroll’ action to a particular name or number and choose to click on a particular name or number. So I googled for that method and I found out that there are two methods, scrollTo(), scrollToExact(), which was supposed to solve my problem. But when  I started writing the code and again I faced another problem.  I am using appium java client 5.0.0-BETA9 (updated version )and on this version, there are no such methods like scrollTo() or scrollToExact().  Previously I had worked on the seetest tool and it is a mobile automation tool, there was a method called ‘swipewhileNotFound’ which would scroll the app view until the desired object was visible.  SeeTest is a licensed tool. Hence there are several readymade methods available for automating mobile application.  So I started writing this method for appium because I needed this method for appium to work.


I have used TestNG to write the test, but you can use any testing framework or simple Java class with the method mentioned above. I have posted my code here so that you can have a look at it. Also, you can download the complete java file from the below link
