Data flow testing (DFT) focuses on the flow of data through a program. Despite its higher fault-detection ability over other structural testing techniques, practical DFT remains a significant challenge. This paper tackles this challenge by introducing a hybrid DFT framework: (1) The core of our framework is based on dynamic symbolic execution (DSE), enhanced with a novel guided path search to improve...
When using Software Architecture documents (ADs), users typically "forage" for information. However, it is little understood how they do this foraging or how to structure architecture documentation to assist them. We conducted a survey of two different groups of foragers, industry practitioner and academic AD users, to investigate issues -- types of forages, foraging sequences and styles...
Navigating and understanding complex software architecture documentation is often challenging. To support finding relevant information in architecture documents (ADs), we propose a semi-automated approach based on the actual usage of ADs by previous users, i.e. by capturing users' exploration paths through ADs and making these paths available for future retracing and analysis. To do this, we have...
This paper describes a software architecture documentation tool (KaitoroBase) built within the Thinkbase Visual Wiki to provide support for non-linear navigation and visualization of Software Architecture Documents (SADs) produced using the Attribute-Driven Design (ADD) method. This involves constructing the meta-model for the SAD in Freebase which provides the foundation for the graph-based interactive...
Model-driven development is worthy of further research because of its proven capabilities in increasing productivity and ensuring correctness. However, it has not yet been explored for multi-core processor-based embedded systems, whose programming is even more complex and difficult that that for conventional uni-processor systems. We propose a new VERTAF/Multi-Core (VMC) framework to bridge this gap...
