Research Projects

We developed a fault-localization technique that utilized correlation-based heuristics. The technique and tool was called Tarantula.  Tarantula uses the pass/fail statuses of test cases and the events that occurred during execution of each test case to offer the developer recommendations of what may be the faults that are causing test-case failures. The intuition of the approach is to find correlations between execution events and test-case outcomes --- those events that correlate most highly with failure are suggested as places to begin investigation.

One of the most difficult tasks in debugging software for a developer is to understand the nature of the fault. Techniques have been proposed by researchers that can help *locate* the fault, but mostly neglected is a way to describe the nature of the fault. We are developing software models, visualizations, and techniques to aid in the diagnosis of the faults in the software.

Cross-situational personality consistency has been of interest in social psychology since the 1960s. With the advent of the Internet, a new range of “situations” has been presented for investigating human behavior in online environments.

Multi-criteria test-suite minimization aims to remove redundant test cases from a test suite based on some criteria such as code coverage, while trying to optimally maintain the capability of the reduced suite based on other criteria such as fault-detection effectiveness. Existing techniques addressing this problem with integer linear programming claim to produce optimal solutions. However, the multi-criteria test-suite minimization problem is inherently nonlinear, due to the fact that test cases are often dependent on each other in terms of test-case criteria.

ArchStudio is an open-source software and systems architecture development environment developed by the Institute for Software Research at the University of California, Irvine. It is an environment of integrated tools for modeling, visualizing, analyzing and implementing software and systems architectures. It is based on the Eclipse open development platform.

ISR has long been an internationally recognized leader in research into all aspects of open source software development. In this role, researchers at ISR along with colleagues throughout the U.S. helped to develop a new agenda that can help guide future research into open source software development.

This project describes and documents observational results that arise from the playtesting­-based evaluation of twenty-­six computer games focused on science learning or scientific research. We refer to this little studied genre of computer games as science learning games (SLGs). Our goal was to begin to identify a new set of criteria, play mechanics, and play experiences that give rise to play­-based learning experiences in the realm of different scientific topics.
