Cyber-physical system (CPS) development tool chains are widely used in the design, simulation, and verification of CPS data-flow models. Commercial CPS tool chains such as MathWorks' Simulink generate artifacts such as code binaries that are widely deployed in embedded systems. H…
Abnormal working hours can reduce work health, general well-being, and productivity, independent from a profession. To inform future approaches for automatic stress and overload detection, this paper establishes empirically collected measures of the work patterns of software engi…
Interaction data, gathered from developers' daily clicks and key presses in the IDE, has found use in both empirical studies and in recommendation systems for software engineering. We observe that this data has several characteristics, common across IDEs:
Can the execution of software be perturbed without breaking the correctness of the output? In this paper, we devise a protocol to answer this question from a novel perspective. In an experimental study, we observe that many perturbations do not break the correctness in ten subjec…
In goal-oriented requirements engineering approaches, conflict analysis has been proposed as an abstraction for risk analysis. Intuitively, given a set of expected goals to be achieved by the system-to-be, a conflict represents a subtle situation that makes goals diverge, i.e., n…
In software and hardware testing, generating multiple inputs which satisfy a given set of constraints is an important problem with applications in fuzz testing and stimulus generation. However, it is a challenge to perform the sampling efficiently, while generating a diverse set …
Mobile apps have become ubiquitous. For app developers, it is a key priority to ensure their apps' correctness and reliability. However, many apps still suffer from occasional to frequent crashes, weakening their competitive edge. Large-scale, deep analyses of the characteristics…
Motivation: The security of any system is a direct consequence of stakeholders' decisions regarding security requirements. Such decisions are taken with varying degrees of expertise, and little is currently understood about how various demographics - security experts, general com…
In practice, a program may contain multiple bugs. The simultaneous presence of these bugs may deteriorate the effectiveness of existing fault-localization techniques to locate program bugs. While it is acceptable to use all failed and successful tests to identify suspicious code …
Detecting emerging issues (e.g., new bugs) timely and precisely is crucial for developers to update their apps. App reviews provide an opportunity to proactively collect user complaints and promptly improve apps' user experience, in terms of bug fixing and feature refinement. How…
The number of malicious Android apps has been and continues to increase rapidly. These malware can damage or alter other files or settings, install additional applications, obfuscate their behaviors, propagate quickly, and so on. To identify and handle such malware, a security an…
Debugging software failures is still a painful, time consuming, and expensive process. For instance, recent studies showed that debugging activities often account for about 50% of the overall development cost of software products [3]. There are many factors contributing to the co…
Modern code reviews improve the quality of software products. Although modern code reviews rely heavily on human interactions, little is known regarding whether they are performed fairly. Fairness plays a role in any process where decisions that affect others are made. When a sys…
We use Grounded Theory to study the evolution of requirements practices of 16 software startups as they grow and introduce new products and services. These startups operate in a dynamic environment, with significant time and market pressure, and rarely have time for systematic re…
Distributed systems are difficult to debug and understand. A key reason for this is distributed state, which is not easily accessible and must be pieced together from the states of the individual nodes in the system.
To implement a program functionality, developers can reuse previously written code snippets by searching through a large-scale codebase. Over the years, many code search tools have been proposed to help developers. The existing approaches often treat source code as textual docume…
Multi-objective evolutionary algorithms (MOEAs) have been successfully applied for software product lines (SPLs) to search for optimal or near-optimal solutions that balance multiple objectives. However, MOEAs usually produce invalid solutions that violate the constraints predefi…
A significant amount of time is spent by software developers in investigating bug reports. It is useful to indicate when a bug report will be closed, since it would help software teams to prioritise their work. Several studies have been conducted to address this problem in the pa…
Privacy by design (PbD) is a policy measure that calls for embedding privacy into the design of technologies at early stages of the development process and throughout its lifecycle. By introducing privacy considerations into the technological design, PbD delegates responsibility …
The Android platform has been the dominant mobile platform in recent years resulting in millions of apps and security threats against those apps. Anti-malware products aim to protect smartphone users from these threats, especially from malicious apps. However, malware authors use…
