* @fileoverview Unit tests for storage mechanism sharing.

|
*
|
|
* These tests should be included in tests of any storage mechanism in which
|
|
* separate mechanism instances share the same underlying storage. Most (if
|
|
* not all) storage mechanisms should have this property. If the mechanism
|
|
* employs namespaces, make sure the same namespace is used for both objects.
