# This script does the following:
# 1. Retrieves gcloud service account token
# 2. Activates gcloud service account
# 3. Connects to google Firebase (using TestArmada's Flank tool)
# 4. Executes UI tests
# 5. Puts test artifacts into the test_artifacts folder

# NOTE:
# Flank supports sharding across multiple devices at a time, but gcloud API
# only supports 1 defined APK per test run.


# If a command fails then do not proceed and fail this script too.
