SUnit
Appearance
SUnit is a unit testing framework for Smalltalk. It is the original source of the xUnit design, originally written by the father of Extreme Programming, Kent Beck. SUnit allows one to write the tests and check results in Smalltalk; while this approach has the disadvantage that testers need to be able to write simple Smalltalk programs, the resulting tests are very stable.
