You can manage your project's testers in the Testers & Groups tab of the App Distribution page (in the Firebase console). This tab allows you to:
- Add new testers (you can also add new testers when you set up a distribution).
Import testers from CSV files.
The CSV file must contain the tester's email address. It can also contain the tester's name (optional) in the same row. For example:
firstname.lastname@example.org,Ali Smith ,email@example.com Cal Nguyen,firstname.lastname@example.org
- Assign testers to groups. For example, you could create one group for your iOS testers and another for your Android testers. You can then invite all of a group's members to test a new build.
Firebase App Distribution has the following tester limits:
Add a maximum of 500 testers to a Firebase project
Add a maximum of 200 testers to an App Distribution group
Add a maximum of 200 testers per distribution
To add more testers, request a free limit increase.
