The code was not much to look at.  We mostly rspec’d a few methods and learned that just because you ‘def to_s’ doesn’t mean the implicit string conversion uses it!
I think the real issue we uncovered was that the implicit string conversion produces escaped string and calling #to_s produces unescaped strings.

Ruby Gems we used to setup the environment.

• rspec
• ZenTest
• redgreen (for windows users)

heredocs — we talked about how to produce heredocs   You can either use multi-line double-quoted, or <<-eot

text = <<-eot
This is the heredoc text
It can even include evaluations #{Time.now} !!
eot
