I've created a Rails Mountable App and added 'mongoid' and 'rspec' gem's. If I try to run my specs now I get the following error:

Mongoid::Errors::NoSessionConfig:  
Problem:
  No configuration could be found for a session named 'default'.
Summary:
  When attempting to create the new session, Mongoid could not find a session configuration for the name: 'default'. This is necessary in order to know the host, port, and options needed to connect.
Resolution:
  Double check your mongoid.yml to make sure under the sessions key that a configuration exists for 'default'. If you have set the configuration programatically, ensure that 'default' exists in the configuration hash.

When I add the Mongoid.load!(Rails.root.join("config", "mongoid.yml")) line to spec_helper.rb everything works normal.

Q: Why is that? And how can I get the functionality like in a normal Rails app where I don't need to call the load function?

Versions:

gem "rails", "~> 3.2.12"
gem 'mongoid', '~> 3.1'
gem 'rspec-rails', '~> 2.13'
