SUnit
SUnit is a unit testing framework for the Smalltalk programming language. It is one of the earliest implementations in the xUnit family, and it helped establish the conventional structure and terminology used by many later testing frameworks for object-oriented languages. SUnit originated with Smalltalk environments, where it provided a lightweight mechanism for automated testing within the Smalltalk image.
The framework centers on the concept of a TestCase class. Tests are defined as methods on subclasses
In practice, SUnit includes test discovery and execution through a test runner, which aggregates results into
Impact and legacy: SUnit is widely cited as a foundational example of the xUnit architecture. Its design
