- Capture gcloud auth stderr separately and fail on unexpected output;
ignore the two known informational lines ("Activated service account
credentials for: [...]" and "Updated property [core/project].") while
keeping a strict "fail if unknown stderr" check for anything else.
- Replace the narrow pattern grep (non-retryable error|infrastructure_failure|
test execution failed) with a broad whole-word case-insensitive grep for
'error', so any infrastructure or Firebase error in the output causes CI
failure.
- Verify that the number of device result rows in the result table matches
the expected device count (1), so a silent test-run failure cannot slip
through.
- Add scripts/test_firebase_check.sh with 18 unit tests for the three new
bash patterns (auth stderr filter, error-word detection, device count).
