Prelaunch reports
Firebase Test Lab offers a service to upload and publish your application to alpha or beta channels in the Google Play console. The prelaunch report is enabled by Robo test. You can Robo test an application for target-specific devices, locales, or different versions of Android. Robo tests can be more customizable than the prelaunch report.
Robo test is preferred for testing APKs. If you are using Test Lab for a large application, it might be a good idea to upgrade the plan to support the application. You can use CI as described in previous sections to make use of build deploy automation and testing.
