I released version 1.1.0
RAA: http://www.ruby-lang.org/en/raa-list.rhtml?name=csv
CVS: http://www.ruby-lang.org/~knu/cgi-bin/cvsweb.cgi/lib/csv/

It contains UnitTest script which covers 99.85% of source
line (not C1, not C0 but source line coverage).  See
coverage.rb and coverage.txt at
http://www.ruby-lang.org/~knu/cgi-bin/cvsweb.cgi/lib/csv/tests/

coverage.rb may be useful to check your UT.  Try
$ ruby -rcoverage targetScript.rb
