GCP Scenario

Mobile Automation Matrix with Firebase Test Lab

Per-PR Android matrix tests on real devices; results streamed to BigQuery; merge gated in Cloud Build.

Architecture

Cloud Build (on PR) ─► gradle assembleDebug + assembleAndroidTest
                ─► gcloud firebase test android run (matrix: 4 devices)
                ─► results in GCS + Firebase console
                ─► Cloud Function parses summary → BigQuery
                ─► Pub/Sub blocks merge until pass

Services used

Cloud Build Firebase Test Lab Cloud Storage BigQuery Pub/Sub

Steps

1. Build APKs
Cloud Build produces app + test APKs.
2. Matrix run
Test Lab runs Espresso on 4 device profiles in parallel with video + perf capture.
3. Aggregate
Function parses Test Lab GCS results and writes per-device rows to BigQuery.
4. Gate
Pub/Sub message updates GitHub commit status; merge blocked on failure or perf regression.

Takeaways

Real-device automation as a hard merge gate.
Historical data enables device-specific flake and perf detection.
