http://matthewfawcett.co.uk en-us 40 <p>I was banging my head against the wall when trying to test the sending of an email in a Rails 3 app with Sinatra / Email Spec and getting the following error message:</p> <pre><code> undefined method `parameters' for #&lt;Mail::UnstructuredField:0x2eceecc&gt; </code></pre> <p>I was using the latest versions of all the gems in my GemFile and the error did not occur outside of Cucumber. I finally tracked the issue down to the fact that the command line <code>cucumber</code> in system gems was an old version. This was causing the issue even though the latest cucumber was declared in my GemFile.</p> <p>I couldn't find anything through Google for the error message so though I would post here incase anyone else runs into the same problem.</p> Thu, 25 Mar 2010 14:06:00 +0000 urn:uuid:40bbe1ee-bf56-4b0f-8c97-142d4c59cf01 http://matthewfawcett.co.uk/2010/03/25/rails-3-cucumber-error-undefined-method-parameters-for-mail-unstructured-field#comments cucumber rails3 http://matthewfawcett.co.uk/2010/03/25/rails-3-cucumber-error-undefined-method-parameters-for-mail-unstructured-field
