For the simple stuff, dust is my tool of choice. Its a very simple
wrapper around
Test::Unit, so there is a shallow learning curve, but you get
meaningful test names,
and it is very easy to generate large blocks of tests from arrays of
inputs. Handy
for black box testing, testing regexes etc.

Shoulda and RSpec I think are tackling different needs. The learning
curve is greater
and there is more magic involved, but I suspect that test
organisation, and consolidation
of reporting is probably a greater priority than natural language test
description.

In addition, check out JtestR for plain old Java testing (it works great).

Theres a team integrating Ruby into visual studio, I can't recall offhand.

I haven't found a good solution for out of the box test reporting in Ruby.
RSpec has some great reporting, but I need something a bit more turnkey.

I currently use dust to test java code through JtestR on top of an existing
Java build system (so our test reporting is done through JUnit reports and
cobertura works for our code coverage of the java code).
