ruby--ruby/test/ruby/test_defined.rb
nahi aaf5d9c03c * test/ruby: tests for ruby itself.
* test/ruby/test_*.rb: split sample/test.rb into 28 test/unit testcases.  some
  tests could not be translates...  search '!!' mark to see it.

* test/csv/test_csv.rb: should require 'csv', not '../lib/csv'.  test runner
  should set load path correctly.
