/**

* @fileoverview This module simplifies testing code which uses stateful
|
|
* singletons. {@code goog.testing.singleton.reset} resets all instances, so
|
|
* next time when {@code getInstance} is called, a new instance is created.
|
|
* It's recommended to reset the singletons in {@code tearDown} to prevent
|
|
* interference between subsequent tests.
|
|
*
|
|
* The {@code goog.testing.singleton} functions expect that the goog.DEBUG flag
|
|
* is enabled, and the tests are either uncompiled or compiled without renaming.
