title: google play alpha and beta tester function
body: <p>I have a question regarding the new <strong>Play Developer Console functions</strong> (Alpha &amp; Beta Testing) , maybe somebody has some experience with it.</p>
  
  <p>I invited some testers by GoogleGroups and they are receiving the invitation and can accept it.</p>
  
  <p>I want to test a paid app. Do they have to pay for testing? this app is unpublished in the store yet but. </p>
  
  <p>I have doubts to set it to free and later I cannot change to paid app.</p>
  
  <p>any suggestions how to proceed?</p>
