Testability and Software Performance : A Systematic Mapping Study

In most of the research on software testability, functional correctness of the software has been the focus while the evidence regarding testability and non-functional properties such as performance is sporadic. The objective of this study is to present the current state-of-the-art related to issues of importance, types and domains of software under test, types of research, contribution types and design evaluation methods concerning testability and software performance. We found that observability, controllability and testing effort are the main testability issues while timeliness and response time (i.e., time constraints) are the main performance issues in focus. The primary studies in the area use diverse types of software under test within different domains, with real-time systems as being a dominant domain. The researchers have proposed many different methods in the area, however these methods lack implementation in practice as suggested by our figures for research type, contribution type and design evaluation methods.TOCSY
