But this was just an example; if this works then you can do it dynamically.

How about something like:

$test_classes = []

fixtures = [TYPE1, TYPE2, TYPE3]
fixtures.each do |f|
  klass = Class.new(TC_CreateOrder)
  klass.const_set(:FIXTURE, f)
  $test_classes << klass  # to prevent garbage collection
end
