/**
* Allows integration and testing for projects with Doctrine2 ORM.
* Doctrine2 uses EntityManager to perform all database operations.
*
* When using with Zend Framework 2 or Symfony2 Doctrine connection is automatically retrieved from Service Locator.
* In this case you should include either **Symfony2** or **ZF2** module and specify it as dependent for Doctrine:
*
* ```
* modules:
* enabled:
* - Symfony2
* - Doctrine2:
* depends: Symfony2
* ```
*
* If you don't use any of frameworks above, you should specify a callback function to receive entity manager:
*
* ```
* modules:
* enabled:
* - Doctrine2:
* connection_callback: ['MyDb', 'createEntityManager']
*
* ```
*
* This will use static method of `MyDb::createEntityManager()` to establish EntityManager.
*
* By default module will wrap everything into transaction for each test and rollback it afterwards. By doing this
* tests won't write anything to database, and so will run much faster and will be isolate dfrom each other.
* This behavior can be changed by specifying `cleanup: false` in config.
*
* ## Status
*
* * Maintainer: **davert**
* * Stability: **stable**
* * Contact: codecept@davert.mail.ua
*
* ## Config
*
* * cleanup: true - all doctrine queries will be run in transaction, which will be rolled back at the end of test.
* * connection_callback: - callable that will return an instance of EntityManager. This is a must if you run Doctrine without Zend2 or Symfony2 frameworks
*
* ### Example (`functional.suite.yml`)
*
* modules:
* enabled: [Doctrine2]
* config:
* Doctrine2:
* cleanup: false
*
* ## Public Properties
*
* * `em` - Entity Manager
