Big Data technology has discarded traditional data modeling approaches as no longer applicable to distributed data processing. It is, however, largely recognized that Big Data impose novel challenges in data and infrastructure management. Indeed, multiple components and procedures must be coordinated to ensure a high level of data quality and accessibility for the application layers, e.g., data analytics...
Coverage criteria aim at satisfying test requirements and compute metrics values that quantify the adequacy of test suites at revealing defects in programs. Typically, a test requirement is a structural program element, and the coverage metric value represents the percentage of elements covered by a test suite. Empirical studies show that existing criteria might characterize a test suite as highly...
Regression testing ensures that previous faults do not recur. When a fault is reported and fixed, the testing team augments the test suite with a new test case that exercises the fault in the original program. Typically the new test case covers patterns of program elements associated with the fault. However, this test might become obsolete (i.e., does not cover the targeted patterns anymore) when...
Researchers in the dynamic program analysis field have extensively used cluster analysis to address various problems. Typically, the clustering techniques are applied onto execution profiles having high dimensionality (i.e., involving a large number of profiling elements), sometimes in the order of thousands or even hundreds of thousands. Our concern is that the high number of profiling elements might...
Typically, oracles used to test graphical user interface(GUI) programs highly depend on environmental factors that are not related to the functionality of the program, such as screen resolution and color schemes. To accommodate these on-functional variations, researchers suggested fuzzy comparison rules that determine whether the output of a GUI program matches the oracles. Others suggested computer...
The majority of dynamic software analyses are implemented in the form of fully-automated techniques. Given the limited success of many of these techniques, we explore the use of visualization as the basis for alternative techniques. Specifically, we investigate the use of multivariate visualization scatter plots, which aim at presenting high dimensional data in low dimensions (e.g., 2D). For example,...
Embedded systems typically consist of a composition of a set of hardware and software IP modules. Each module is heavily optimized by itself. However, when these modules are composed together, significant additional opportunities for optimizations are introduced because only a subset of the entire functionality is actually used. We propose COSE-a technique to jointly optimize such designs. We use...
