Firebase In-App Messaging helps you engage users who are actively using your app by sending them targeted and contextual messages that nudge them to complete key in-app actions - like beating a game level, buying an item, or subscribing to content.
The FIAM SDK manages the non-ui logic for FIAM - including fetching new eligible messages from the server, and triggering FIAM messages.
Unit tests:
../gradlew :firebase-inappmessaging:test
Integration tests, requiring a running and connected device (emulator or real):
../gradlew :firebase-inappmessaging:connectedAndroidTest
The best way to the FIAM sdks is via the fiamui-app in this repo - you can run the test, or use Firebase Test Lab to run a series of UI tests. See fiamui-app/scripts for more details
