Assuming you are using unit tests [you ARE using unit tests, right? ;)], 
you would need to use mock objects. An example of this concept is my 
submission to the HighLine Ruby Quiz. In my case I rolled my own mock 
object, but it might be better to use a library, such as this:

But I think the above still needs to be updated for Test::Unit (I think 
it is using the older RubyUnit.)
