Abstract:
When architecting dependable systems, in addition to
improving system dependability by means of construction
(fault-tolerant and redundant mechanisms, for instance),
it is also important to
evaluate, and thereby confirm, system dependability.
There are many different approaches to evaluating system
dependability, and testing always has been an important
one.
Previous work on software architecture testing has shown
it is possible to apply conformance-testing techniques
to yield confidence that the behavior of an implemented
system conforms
to the expected behavior of the software architecture,
specified with Architecture Description Languages (ADLs).
In this work, we explore how regression testing can be
systematically applied at the software architecture
level in order to reduce the cost of retesting modified
systems, and also to assess the regression testability
of the evolved system. We consider assessing both
“top-down” and “bottom-up” evolution, i.e., whether a
slightly modified implementation conforms to the initial
architecture, and whether the (modified) implementation
conform an evolved architecture. A better understanding
on how regression testing can be applied at the software
architecture level will help us to assess and identify
architecture with higher dependability.
