"""Runs semi-automated update testing on a non-rooted device.
This script will help verify that app data is preserved during an update.
To use this script first run it with the create_app_data option.
./update_verification.py create_app_data --old-apk <path> --app-data <path>
The script will then install the old apk, prompt you to create some app data
(bookmarks, etc.), and then save the app data in the path you gave it.
Next, once you have some app data saved, run this script with the test_update
option.
./update_verification.py test_update --old-apk <path> --new-apk <path>
--app-data <path>
This will install the old apk, load the saved app data, install the new apk,
and ask the user to verify that all of the app data was preserved.
