After you build your Android App Bundle, you should test how Google Play uses it to generate APKs and how those APKs behave when deployed to a device. There are two ways you should consider testing your app bundle: locally using the bundletool command line tool and through Google Play by uploading your bundle to the Play Console and using a test track. This page explains how to use bundletool to test your app bundle locally.

Installation Steps:

1. Open Terminal using Spotlight search by pressing  <command+space>.
   Type terminal and hit  Enter key.
2. Now, run
   ruby -e “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)” < /dev/null 2> /dev/null
3. Install bundletool using brew
   brew install bundletool

bundletool is ready to use now!

bundletool is the underlying tool that Gradle, Android Studio, and Google Play use to build an Android App Bundle or convert an app bundle into the various APKs that are deployed to devices. bundletool is also available to you as a command line tool, so you can recreate, inspect, and verify Google Play’s server-side build of your app’s APKs.
