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

1.17 + *
1.18 + * 1. Notifies to the offline cache update service about a fake
1.19 + * low device storage situation.
1.20 + * 2. Schedules an update and observes for its notifications.
1.21 + * 3. We are supposed to recieve an error event notifying about the cancelation
1.22 + * of the update because of the low storage situation.
1.23 + * 4. Notifies to the offline cache update service that we've recovered from
1.24 + * the low storage situation.
