| """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. |
