This evening I spent a few minutes (literally) and whipped a small hack
("spike" for you XPers among us) of a Ruby version of TestDox
(see AgileDox).
I’m going to use it on my own code for a while before doing anything
proper with it. Right now, it’s a whopping 37 lines of Ruby. If
you’re interested, have a look here:

You can run it like so:

  ruby testdox.rb test_source1.rb test_source2.rb (etc.)
