Wearable devices are becoming increasingly popular. These wearable devices run what is known as wearable apps. Wearable apps are packaged with handheld apps, that must be installed on the accompanying handheld device (e.g., phone).
We present a Bayesian framework for learning probabilistic specifications from large, unstructured code corpora, and then using these specifications to statically detect anomalous, hence likely buggy, program behavior. Our key insight is to build a statistical model that correlat…
Finding the optimally performing configuration of a software system for a given setting is often challenging. Recent approaches address this challenge by learning performance models based on a sample set of configurations. However, building an accurate performance model can be ve…
Scenario-finding tools like the Alloy Analyzer are widely used in numerous concrete domains like security, network analysis, UML analysis, and so on. They can help to verify properties and, more generally, aid in exploring a system's behavior.
Numerical invariants, e.g., relationships among numerical variables in a program, represent a useful class of properties to analyze programs. General polynomial invariants represent more complex numerical relations, but they are often required in many scientific and engineering a…
Software project scheduling, under uncertain and dynamic environments, is one of the most important challenges in software engineering. Recent studies addressed this challenge in both static and dynamic scenarios for small and medium size software projects. The increasing trend o…
As software projects evolve, carefully understanding the behavior of a program is mandatory before making any change. Repetitive code snippets also tend to appear throughout the codebase, and developers have to understand similar semantics multiple times. Building on this observa…
Software Product Lines (SPLs) are highly configurable systems. This raises the challenge to find optimal performing configurations for an anticipated workload. As SPL configuration spaces are huge, it is infeasible to benchmark all configurations to find an optimal one. Prior wor…
Co-change dependencies arise whenever two source code entities, such as classes, methods, or fields, change frequently together. Similar to other kinds of software dependencies, it is possible to build software clusters from co-change relationships and, as such, previous studies …
We propose a novel methodology that allows automatic construction of benchmarks for Static Analysis Security Testing (SAST) tools based on real-world software projects by differencing vulnerable and fixed versions in FOSS repositories. The methodology allows us to evaluate ``actu…
In this paper we present VART, a tool for automatically revealing regression faults missed by regression test suites. Interestingly, VART is not limited to faults causing crashing or exceptions, but can reveal faults that cause the violation of application-specific correctness pr…
Source Code Management (SCM) systems support software evolution by providing features, such as version control, branching, and conflict detection. Despite the presence of these features, support to parallel software development is often limited. SCM systems can only address a sub…
Application containers, such as those provided by Docker, have recently gained popularity as a solution for agile and seamless software deployment. These light-weight virtualization environments run applications that are packed together with their resources and configuration info…
We describe DynAlloy Analyzer, a tool that extends Alloy Analyzer with support for dynamic elements in Alloy models. The tool builds upon Alloy Analyzer in a way that makes it fully compatible with Alloy models, and extends their syntax with a particular idiom, inspired in dynami…
In this paper we present CLTSA (Counting Fluents Labelled Transition System Analyser), an extension of LTSA (Labelled Transition System Analyser) that incorporates counting fluents, a useful mechanism to capture properties related to counting events. Counting fluent temporal logi…
Recent introduction of a dynamic permission system in Android, allowing the users to grant and revoke permissions after the installation of an app, has made it harder to properly test apps. Since an app's behavior may change depending on the granted permissions, it needs to be te…
With the omnipresence of mobile devices coupled with recent advances in automatic speech recognition capabilities, there has been a growing demand for natural language query (NLQ) interface to retrieve information from the knowledge bases. Business users particularly find this us…
Automatic program repair offers the promise of significant reduction in debugging time, but still faces challenges in making the process efficient, accurate, and generalizable enough for practical application. Recent efforts such as Prophet demonstrate that machine learning can b…
The demand for high quality mobile applications is constantly rising, especially in mission critical settings. Thus, new software engineering methodologies are needed in order to ensure the desired quality of an application. The research presented proposes a quality assurance met…
We present CodeCarbonCopy (CCC), a system for transferring code from a donor application into a recipient application. CCC starts with functionality identified by the developer to transfer into an insertion point (again identified by the developer) in the recipient. CCC uses pair…
