title: .env not being loaded in test environment in Rails with rspec
body: <p>I am using <code>gem 'dotenv-rails', '~&gt; 0.9.0'</code> to load environment variables into a Rails 4.0.5 app. I have a .env file along with a .env.test. All is working well in development, however when it comes to testing, which I do with rspec, it is failing to set the environment variables.</p>
  
  <p>I have gone into Rails console in testing environment and I can see they are set to nil.</p>
  
  <p>Any tips on how to get dotenv to load in testing?</p>
