- """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.
