How can we trust functionality that we may not be able to fully test?

SOA:  We must try to test the complete functional envelope (till $$ runs out…)!

Issue:  

Some new Control capabilities are untraceable and/or non-deterministic

Adaptive systems

Huge test space

Perfect Input data

Learning systems

Environmental stimuli

Lost memory

Multi-modal systems

Mode transition stability

Mode synchronization

Recovery mode?

Answer may reside in bounding the function in run-time to known safe behavior.
