    12  * This test checks that an offline cache update scheduled *after* a low device

    13  * storage situation appears is canceled. It basically does:

    14  *

    15  * 1. Notifies to the offline cache update service about a fake

    16  *    low device storage situation.

    17  * 2. Schedules an update and observes for its notifications.

    18  * 3. We are supposed to recieve an error event notifying about the cancelation

    19  *    of the update because of the low storage situation.

    20  * 4. Notifies to the offline cache update service that we've recovered from

    21  *    the low storage situation.
