# The Yaf_Application class

(No version information available, might only be in Git)

## Introducere

Yaf_Application provides a bootstrapping facility for applications which provides reusable resources, common- and module-based bootstrap classes and dependency checking.

> Notă:

> Yaf_Application implements the singleton pattern, and Yaf_Application can not be serialized or unserialized which will cause problem when you try to use PHPUnit to write some test case for Yaf.

> You may use @backupGlobals annotation of PHPUnit to control the backup and restore operations for global variables. thus can solve this problem.
