Well, going by the Pickaxe book you end up with something like this:

./classfilename
->/doc
->/lib
->/test

in ./classfilename/lib you create your ruby source file classfilename.rb
in ./classfilename/test you create your ruby test/unit file 
classfilename_tc.rb

In classfilename_tc.rb you put the following lines at the start:

#----------------------------------------------------------------
# The following prefixes ../lib to the active ruby load path
$:.unshift File.join(File.dirname(__FILE__), "..", "lib")

require 'test/unit'
require 'classfilename'

class Test_ClassFileName  < Test::Unit::TestCase
...
#----------------------------------------------------------------

and then write your test cases as methods.  When you run your test suite 
you can invoke it from any palce on the system as the #unshift prefixes 
the load path with the relative location of the classfilename.rb with 
respect to the test case file.

Thus, assuming that for the example given above that ./ = ~/ruby then:

#ruby -w ~/ruby/classfilename/test/classfilename_tc.rb

will work whatever pwd you are in.

I love test/unit...

Jim
