I started testing with Test::Unit+Shoulda, and then moved to RSpec when I found that it was basically the same thing with less hackery. This was being Minitest existed. Since then, I've stuck with RSpec because it's got a ton of community support, and consistently lets me write concise tests. I never feel like I have to unduly repeat myself with RSpec; I constantly felt like that when I was writing testunit tests.
