Automated Test Case Generation To Validate Non-Functional Software Requirements, Pingyu Zhang

Department of Computer Science and Engineering: Dissertations, Theses, and Student Research

A software system is bounded by a set of requirements. Functional requirements describe what the system must do, in terms of inputs, behavior, and outputs. We define non-functional requirements to be how well these functional requirements are satisfied, in terms of qualities or constraints on the design or on the implementation of a system. In practice, the validation of these kinds of requirements, does not receive equal emphasis. Techniques for validating functional requirements target all levels of software testing phases, and explore both black-box and white-box approaches. Techniques for validating non-functional requirements, on the other hand, largely operate in a …

Solving The Search For Source Code, Kathryn T. Stolee

Department of Computer Science and Engineering: Dissertations, Theses, and Student Research

Programmers frequently search for source code to reuse using keyword searches. When effective and efficient, a code search can boost programmer productivity, however, the search effectiveness depends on the programmer's ability to specify a query that captures how the desired code may have been implemented. Further, the results often include many irrelevant matches that must be filtered manually. More semantic search approaches could address these limitations, yet existing approaches either do not scale, are not flexible enough to find approximate matches, or require complex specifications.

We propose a novel approach to semantic search that addresses some of these limitations and …
