A simple test of mountain_berry_fields (https://github.com/JoshCheek/mountain_berry_fields). I'm working on the RestClient gem and trying to use mbf to verify some code examples. I'm hitting a roadblock with this one, though: when I try to run it through mbf, I get the cryptic error message "NoMethodError undefined method `write' for File:Class"…

test.txt.mountain_berry_fields

<% setup do %>
require './lib/restclient'
<% end %>

This is a test:

<% test 'generic test', with: :magic_comments do %>
  response = RestClient.get 'http://l2g.github.com/'
  response.code # => 200
<% end %>
