In conjunction with code coverage capabilities provided by the LDRA tool suite, traceability documentation can be produced to demonstrate that all impacted areas have been re-tested to required levels.
This is achieved by taking a baseline copy of the software system under test and then highlighting the impact of subsequent code changes so that any knock-on effects from the change can be tracked and tested with minimal effort.
