DevOps approaches software engineering by advocating the removal of borders between development and operations. DevOps emphasizes operational resilience, continuous feedback from operations back to development, and rapid deployment of features developed. In this talk we will look…
The ModelWriter platform provides a generic framework for automated traceability analysis. In this paper, we demonstrate how this framework can be used to trace the consistency and completeness of technical documents that consist of a set of System Installation Design Principles …
Testing of Android apps is particularly challenging due to the fragmentation of the Android ecosystem in terms of both devices and operating system versions. Developers must in fact ensure not only that their apps behave as expected, but also that the apps' behavior is consistent…
Numerical software is used in a wide variety of applications including safety-critical systems, which have stringent correctness requirements, and whose failures have catastrophic consequences that endanger human life. Numerical bugs are known to be particularly difficult to diag…
Integrated development environments (IDEs) are complex applications that integrate multiple tools for creating and manipulating software project artifacts. To improve users' knowledge and the effectiveness of usage of the available functionality, the inclusion of recommender syst…
There is often more than one way to trigger a fault. Standard static and dynamic approaches focus on exhibiting a single witness for a failing execution. In this paper, we study the problem of computing a comprehensive characterization which safely bounds all failing program beha…
When using formal verification on critical software, an important question involves whether we have we specified enough properties for a given implementation model. To address this question, coverage metrics for property-based formal verification have been proposed. Existing metr…
Fuzzing consists of repeatedly testing an application with modified, or fuzzed, inputs with the goal of finding security vulnerabilities in input-parsing code. In this paper, we show how to automate the generation of an input grammar suitable for input fuzzing using sample inputs…
While Web applications have become pervasive in today's business, social interaction and information exchange, their usability is often deficient, even being a key factor for a website success. Usability problems repeat across websites, and many of them have been catalogued, but …
The rise of Big Data is leading to an increasing demand for data-intensive applications (DIAs), which, in many cases, are expected to process massive amounts of sensitive data. In this context, ensuring data privacy becomes paramount. While the way we design and develop DIAs has …
The real-world big data are largely unstructured, interconnected text data. One of the grand challenges is to turn such massive unstructured text data into structured, actionable knowledge. We propose a text mining approach that requires only distant or minimal supervision but re…
Heap overflow is one of the most widely exploited vulnerabilities, with a large number of heap overflow instances reported every year. It is important to decide whether a crash caused by heap overflow can be turned into an exploit. Efficient and effective assessment of exploitabi…
Reducing the test input given to a program while preserving some property of interest is important, e.g., to localize faults or to reduce test suites. The well-known delta debugging algorithm and its derivatives automate this task by repeatedly reducing a given input. Unfortunate…
In software development, there are many situations in which developers need to understand given source code changes in detail. Until now, a variety of techniques have been proposed to support understanding source code changes. Tree-based differencing techniques are expected to ha…
Sadly we know that virtually all software of any significance has residual errors. Some of those errors can be traced back to requirements flaws or faulty design assumptions; others are just plain coding mistakes. Static analyzers have become quite good at spotting these types of…
While smartphones and mobile apps have been an integral part of our life, modern mobile apps tend to contain a lot of rarely used functionalities. For example, applications contain advertisements and offer extra features such as recommended news stories in weather apps. While the…
A key challenge in software systems that are exposed to runtime variabilities, such as workload fluctuations and service degradation, is to continuously meet performance requirements. In this paper we present an approach that allows performance self-adaptation using a system mode…
Modern software systems provide many configuration options which significantly influence their non-functional properties. To understand and predict the effect of configuration options, several sampling and learning strategies have been proposed, albeit often with significant cost…
Commit messages are a valuable resource in comprehension of software evolution, since they provide a record of changes such as feature additions and bug repairs. Unfortunately, programmers often neglect to write good commit messages. Different techniques have been proposed to hel…
To ensure the quality of Android applications, many automatic test case generation techniques have been proposed. Among them, the Monkey fuzz testing tool and its variants are simple, effective and widely applicable. However, one major drawback of those Monkey tools is that they …
