Why? Just curious...

Try this:

class MySuite < Test::Unit::TestCase

   [:concept_1, :concept_2, :concept_3].each do |thang|
     define_method "test_#{thang}" do
       assert_concept thang
     end
   end

   def assert_concept(thang)
     #  now convert the thang symbol to a real thing and test it
   end

end

> t.send(:define_method, "test_defined_at_run_time", "")

You are trying too hard. define_method is easier than that to call.

And note I put most of the processing _outside_ the define_method. Its only job 
is to construct a test case name and pass in a thang. This helps make 
assert_concept() more comprehensible.
