I'm trying to figure out how to ust Test::Unit.  I've read the 
documentation in:
http://testunit.talbott.ws/doc/index.html

But I'm no closer to understanding it than I was before.  At the end of 
the page, the author says that (s)he'd like to get some feedback.  Whoever 
the author might be, here is some feedback:

1) Include your name and email so that it's easier to send you feedback.
2) Could you include an example of how I'd use Test::Unit?

Here is a simple case.  Say I write a private method to add two numbers:

class MyClass
  private
    def add(a,b)
        return a+b
    end
end

And I want to - say - assert that the return value is larger than the 
first input value.  How can I use Test::Unit to make this assertion?

How can I use Test::Unit to assert in-between steps inside my methods?

Currently I have things like:

condition or raise "condition was not met"

How can I replace this sort of thing by test units?

Thanks.
