title: Trying to run test using 'rspec' but can't due to my omniauth.rb
body: <p>Has my whole testing ability been render useless with the inclusion of Omniauth?
  When running any 'rspec' commands I immediately recieve this error:</p>
  
  <pre><code>config/initializers/omniauth.rb:4:in `block in &lt;top (required)&gt;': uninitialized constant TWITTER_KEY (NameError)
  </code></pre>
  
  <p>TWITTER_KEY has been defined in my /config/environment/development.rb.  Why doesn't Rspec know this? how can I inform rspec of this?</p>
