Use the setup and teardown methods.  Here's how a test case gets run:

test_case =3D YourTestCase.new
test_case.setup
test_case.test_something
test_case.teardown

(A fresh, new YourTestCase instance is created every time.)

Yes :)

You can find a unit test suite for Java, and write code in Groovy.  Word
on the street says Groovy is much like Ruby.
