Overview
Testing with a Mock OS
The OS.getInstance() factory method looks up the "os.class" system property before it looks up "os.name".

An instantiation failure will throw an exception (ClassNotFoundException or other).
In order to mock an OS, provide an OS implementation in your class path and then set "os.class", with a code possibly similar to:
