Google Firebase Test Lab vs. Sauce Labs

Test your app on devices hosted in a Google data center. Firebase Test Lab for Android provides cloud-based infrastructure for testing Android 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.

In a world that relies on code, Sauce Labs strives to make it work for everyone, everywhere and every time. This is digital confidence. Sauce Labs is the leading provider of continuous test and error reporting solutions that gives companies confidence to deliver a trusted digital brand experience to their customers.
