Unit testing in Prothon?

[Roy Smith]

I've read through the Prothon tutorial and must admit there is something 
kind of interesting about the idea of prototypes instead of classes.

My thoughts quickly turned to testing.  If nothing else, classes give us 
a nice place to hang unit tests on.  I can design and test one class at 
a time, then move on to the next one.  What would unit testing look like 
in Prothon?
