Just download and install 1.9 from rubyinstaller.org. It installs Ruby 
1.9 in its own directory by default, so that 1.8.x and 1.9 can coexist 
happily.

You can then install pik, for example (gem install pik), which allows 
you to switch Ruby interpreters (for one console session only) on the 
fly, and you can run your tests.

This, sans pik, is my own setup, and it works rather well.
