Abstract
After changes are made to a previously tested program,
a goal of regression testing is to perform retesting based
on the modifications while maintaining the same testing coverage as
completely retesting the program.
We present a novel approach to
data flow based regression testing that uses slicing algorithms to
explicitly detect
definition-use associations that are affected by a program change.
An important benefit of our slicing technique
is, unlike previous techniques, no data flow history is needed nor is the
recomputation of data flow for the entire program
required to detect affected definition-use associations.
The program changes drive the recomputation of
the required partial data flow through slicing.
Another advantage is that our technique achieves the
same testing coverage with respect to the affected
pairs as a complete retest of
the program without maintaining a test suite.
Thus, the overhead of maintaining and updating a test suite
is eliminated.
