Testability of Object-Oriented Systems

摘要

We have studied the feasibility of building an object-oriented softwaretestability improvement tool that can be sued in conjuction with RST Corporation's C++ Softwre Testability Analysis (TM) or as a standalone assertion injection tool. We have also produced a set of recommended validation and design techniques that will improve testability, and as a side benefit, the testing of OO systems. If awarded a Phase II effort, RST will provide NIST with a means of improving the testability of C++ systems; to do so within the Phase II cost limit, RST will leverage knowledge gained from building next-generation software assessment tools. Here, RST will rely on experience gained during the building of RST's C and Fortran-77 testability tools, as well as the experimental results from the Phase I effect (which required our building a prototype C++ front-end for PiSCES Software Analysis Toolkit(TM)). Such a Phase II innovation can also be used by NIST or other US Government agencies to empirically research the fault masking ability provided between procedural and object-oriented languages.
