Indeed it can:

  require 'test/unit'
  
  module AbstractSuite
    def test_foo()
      p derive()
    end
  end
  
  class ConcreteSuiteA < Test::Unit::TestCase
    include AbstractSuite
  
    def derive()
      return 'like this'
    end
  end
  
  class ConcreteSuiteB < Test::Unit::TestCase
    include AbstractSuite
  
    def derive()
      return 'like that'
    end
  end
  # >> Loaded suite -
  # >> Started
  # >> "like this"
  # >> ."like that"
  # >> .
  # >> Finished in 0.000816 seconds.
  # >> 
  # >> 2 tests, 0 assertions, 0 failures, 0 errors

If you define your shared tests in a module, you can then 'include' it
in any number of suites derived from Test::Unit::TestCase.
