What is Advanced Unit Testing ?
The Advanced Unit Testing frameworking facilitates more complex unit testing by considering not just low level units (methods) but also "compositional units." A compositional unit considers the dependencies between discrete methods, allowing the developer to specify those dependencies and test the
system, not just the individual units. This also includes iterations and performance testing.
