While rspec is indeed nice, I don't get why most projects don't use minitest more. Minitest ships with the Ruby standard library and I much prefer the assert syntax over the rspec DSL.

Rails also uses minitest with fixtures by default, I migrated to it recently and I really like the simplicity.

minitest also provides a spec-style DSL. Rspec is a hog, minitest is much, much cleaner and leaner, even if you use the DSL.
