I don't actually know what he means by that, but I do know that there are cases where I sometimes want a bunch of nearly identical specs, and I generate them in code using enumeration or some other means; ie. dumb example:

Yeah, I think it's a legitimate technique, as long as you don't get too carried away with it.

I use it, for example, for some code quality specs:

  Wincent::SOURCE_FILES.each do |file|
    describe file do
      it 'contains no trailing whitespace' do
        file.should_not have_trailing_whitespace

      it 'contains no tabs' do
        file.should_not contain_tabs

      it 'has a newline at the end' do
        file.should have_newline_at_end_of_file
