Test-unit not found by Ruby but available in gem list

Ruby

Hi All,

When I include “gem ‘test-unit’” in my ruby file, it gives the following
error. However my “gem list” does show test-unit. I am not sure what is
missing when running the file as “ruby ci_reporter.rb”. The actual ruby
file is attached.

Installed the same in another machine, and it worked. Looks like the
problem is due to installation of jruby. I have no clue of how they are
related, but the problem is solved for now.

Some gems are special. Their name is not what you have to require.
This is usually only the case with gems that contain a - in their
name. Such as ‘test-unit’. When this happens you should consult
the gem’s documentation. For example, you should require ‘test-unit’
as ‘test/unit’.
