/*
|
||||
* This test will check that localStorage data are correctly deleted when an app
|
||||
* is uninstalled.
|
||||
* Here is the big picture of what the test does:
|
||||
* 1. Setup permissions and preferences.
|
||||
* 2. Install a dummy application and embed it in an iframe.
|
||||
* 3. Load a mozbrowser iframe from this application.
|
||||
* 4. Fill storages for the app and the mozbrowser iframe.
|
||||
* 5. Uninstall the application.
|
||||
*
|
||||
* Expected result: all localStorage data from the app and mozbrowser have been
|
||||
* deleted but sessionStorage stays untouched such as non-app/browser data.
|
||||
*
|
||||
* This test is asynchronous and methods are called in a reading order.
|
||||
* Each method has a deeper explanation of what it does
