The idea is that the system assumes that the programmer will only send messages to objects that understand them, and raise an exception when that doesn't happen. I find it unlikely that I intentionally send a message to an object that doesn't understand it. That only seems to happen when I try to use third-party libraries that I don't understand yet, and that's why I write Learning Tests.

RE: OT: Smalltalk (RE: OT: OO Newcomer)

Well, there used to be a fairly good paper here: http://rain.create.ucsb.edu/~stp/CD-ROM/Tutorials/SqueakFromJava/squeak_ tutorial.html, but that seems to be inactive. Stay tuned, I will try to find out where it is. Also, the documentation on the Squeak Swiki hosted at Georgia Tech is fairly comprehensive. =jason [:question | ^One] -----Original Message----- From: J. B.

Re: FAQ Update

And I, in turn, wish to pass the majority of the credit on to Steffen Gemkow -- both for JUnitDoclet which got me started on this long overdue process, and for the extradorinarily patient assistance he gave me in figuring out how JUnit works.
