No adapter set exception when setting multiple connections in li3

I am attempting to set-up multiple connections in my li3 project but when I do I get an uncaught exception. I set my connections in the app/confi/bootstrap/connections.php file which is then loaded in by the bootstrap.php file. Here is what I have for my connections:

 Connections::add('default', array(
    'development' => array(
            'type' => 'MongoDb',
            'host' => 'localhost',
            'database' => 'web_app'
    ),
    'test' => array(
        'type' => 'MongoDb',
        'host' => 'localhost',
        'database' => 'test_web_app'
    )
)
);

When I have it set like this and try to browse to my project I get this error:

 Fatal error: Uncaught exception 'lithium\core\ConfigException' with message 'No adapter set for configuration in class `lithium\data\Connections`.' in /var/www/site/libraries/lithium/core/Adaptable.php:233

However when I just have a single default connection set-up it works fine. Has anyone else ran into this issue?
