Firebase Test Lab provides cloud-based infrastructure for testing Android and iOS apps. This includes test experience integrated into Android Studio, gcloud command-line tool, and Firebase Console. For comprehensive testing before releasing your app, Firebase Test Lab gives you access to physical & virtual devices installed and running in a Google data center.
Firebase Test Lab is a component of the Firebase suite and provides cloud-based infrastructure for testing Android and iOS apps. With one operation you can initiate testing of your app across a wide variety of devices and device configurations. Test results — including logs, videos, and screenshots — are made available in your project in the Firebase Console. Even if you haven't written any test code for your app, Test Lab can exercise your app automatically, looking for crashes.
