Testing javascript

Hi,

I have two select lists in my app called 'topic' and 'member'.
Based on what I select in topic, member is populated accordingly (using
java script).
eg. If I select 'subject1' in topic, member should be populated with the
values 'prof x', 'prof y' and 'prof z'.
Can I test that my java script function is populating member with the
correct values in a unit test?

Not really, since your ruby code doesn't know how to execute
javascript. (I often use the Test.Unit stuff from prototype to write
javascript unit tests)
