- Regression Testing
- Assures that anything unchanged still performs correctly. All unchanged
a system components still function as expected and all manual procedures
surrounding the systems are still correct. The potential scope of testing
is theoretically largest in regression testing since the entire universe

be retested to assure no negative unplanned impacts. In fact, risk assessment
can be used to dramatically limit the scope of regression testing to
those technology and documentation components that are reasonably at
