title: Empty email body with action mailer and rspec
body: <p>I have one test case where i want to test the body of the email:</p>
  
  <pre><code>last_email.to.should include(user.email)
  last_email.body.should match(user.email)
  </code></pre>
  
  <p>But the body is always empty when i run rspec:</p>
  
  <pre><code> Failure/Error: last_email.body.encoded.should match(user.email)
     expected "" to match "louise.denis@thomas.eu"
  </code></pre>
  
  <p>the sender/recipients/subject fields are all OKs. How can I access the body of the email (encoded in HTML)?</p>
