Real Database Testing
Some of the tests run on a real database. To enable them, copy config.example.php to config.php in tests directory, fill in the database details and run phpunit again.
Testing With DB Facade
DB class is a static proxy to a DatabaseManager instance. Use the DB::setFacadeRoot() method to pass a mock object. It accepts only a DatabaseManager instance so a stub has to be created.
class DatabaseManagerStub extends DatabaseManager
{
    public function __construct()
    {
    }
}
...
// inside test method
$mock = $this->getMock('DatabaseManagerStub');
DB::setFacadeRoot($mock);
See the tests directory for more examples.
