Shoulda has been great for testing, and is really easy to condense. So let's refactor a shoulda test.

class PostTest < Test::Unit::TestCase
  should_ensure_length_in_range :zip, (6..10)
  should_ensure_length_in_range :title, (3..20)
  should_ensure_lenght_in_range :phone, (7..10)
end

Now refactored:

class PostTest < Test::Unit::TestCase
  {:zip => (6..10), :title => (3..20), :phone => (7..10)}.each_pair do |field, range|
    should_ensure_length_in_range field, range
  end
end

And there we have it. Condensed code, and if you have enough of these fields it can really save some key strokes.
