You can use Open testing to release your app only for beta users, but, In the special case of paid applications, the users will be asked to pay the real price of the app, even if is an Open Testing version. If you want to allow free access to the testers (for example, the QA team) you must also use Sandbox Testing. In this article I’m going to show you how to distribute a free version of your app with Open Testing.
Note: For paid apps is strongly recommended to add the DRM SDK.
Previous Requirements

Releasing the Open Testing version
Open testing allows you to distribute a Beta version of your app in order to get feedback and make improvements before releasing for all.
Note: Open Testing is now in Beta State, follow this guide to enable it.
From My apps, choose the app to be relesed and pepare the release of a new version.
Under Open Testing fill the next information:

Feedback email address: Email where the users can give feedback and report issues.

Once you have filled all the release information, click on Submit. If your app passes the manual/automatic review, all users in the list will receive an invitation to participate in the beta test. If a user accepts the invitation, will be able to find the beta version of your app in AppGallery
Conclusion
