User Comments:
mdeggersbeans: I was attempting to create a JUnit test suite so I wouldn't have to perform set up and tear down operations for each test.  I did the following:

Right mouse clicked on the package
Selected New-->Other
Selected JUnit
Selected Test Suite
Named the test suite and left all checkboxes selected

I have not tried this in Netbeans 6.1
