Research in the fields of software quality and maintainability requires the analysis of large quantities of data, which often originate from open source software projects. Pre-processing data, calculating metrics, and synthesizing composite results from a large corpus of project …
Since manual black-box testing of GUI-based applications (GAPs) is tedious and laborious, test engineers create test scripts to automate the testing process. These test scripts interact with GAPs by performing actions on their GUI objects. An extra effort that test engineers put …
This paper introduces UniFi, a tool that attempts to automatically detect dimension errors in Java programs. UniFi infers dimensional relationships across primitive type and string variables in a program, using an inter-procedural, context-sensitive analysis. It then monitors the…
Software debugging is time-consuming and effort-consuming. Although software debugging, especially fault-localization, has been studied for long, few practical debugging tools have been developed and used by the industry. In this paper we present VIDA, a visual interactive debugg…
Predicting the incidence of faults in code has been commonly associated with measuring complexity. In this paper, we propose complexity metrics that are based on the code change process instead of on the code. We conjecture that a complex code change process negatively affects it…
Based on a well-defined component architecture the tool supports the synthesis of so-called real-time statecharts from timed sequence diagrams. The two step synthesis process addresses the existing scalability problems by a proper decomposition and allows the user to define parti…
As software systems continue to grow and evolve, locating code for maintenance and reuse tasks becomes increasingly difficult. Existing static code search techniques using natural language queries provide little support to help developers determine whether search results are rele…
Test-suite minimization techniques aim to eliminate redundant test cases from a test-suite based on some criteria, such as coverage or fault-detection capability. Most existing test-suite minimization techniques have two main limitations: they perform minimization based on a sing…
One of the challenges in software development is to collect and analyze the end users' feedback in an effective and efficient manner. In this paper we present a tool to manage user evaluation alongside the process of software development. The tool is based on the idea that user e…
The area of clone detection has considerably evolved over the last decade, leading to approaches with better results, but at the same time using more elaborate algorithms and tool chains. In our opinion a level has been reached, where the initial investment required to setup a cl…
Code cloning is not only assumed to inflate maintenance costs but also considered defect-prone as inconsistent changes to code duplicates can lead to unexpected behavior. Consequently, the identification of duplicated code, clone detection, has been a very active area of research…
Tools support is crucial for the acceptance of a new programming language. However, providing such tool support is a huge investment that can usually not be provided for a research language. With FeatureIDE, we have built an IDE for AHEAD that integrates all phases of feature-ori…
We present a technique for finding security vulnerabilities in Web applications. SQL Injection (SQLI) and cross-site scripting (XSS) attacks are widespread forms of attack in which the attacker crafts the input to the application to access or modify user data and execute maliciou…
Software engineers often inspect program differences when reviewing others' code changes, when writing check-in comments, or when determining why a program behaves differently from expected behavior after modification. Program differencing tools that support these tasks are limit…
The complexity of today's software systems is constantly increasing. As a result, requirements for these systems become more comprehensive and complicated. In this setting, requirements engineers struggle to capture consistent and complete requirements of high quality. We propose…
Classic fault localization techniques can automatically provide information about the suspicious code blocks that are likely responsible for observed failures. This information is useful, but not sufficient to completely understand the causes of failing executions, which still re…
Before performing drastic changes to a project, it is worthwhile to thoroughly explore the available options within the current structure of a project. An alternative to drastic change are internal changes that adjust current options within a software project. In this paper, we s…
AJAX-based Web 2.0 applications rely on stateful asynchronous client/server communication, and client-side runtime manipulation of the DOM tree. This not only makes them fundamentally different from traditional web applications, but also more error-prone and harder to test. We pr…
Code ownership transfer or succession is a crucial ingredient in open source code reuse and in offshoring projects. Measuring succession can help understand factors that affect the success of such transfers and suggest ways to make them more efficient. We propose and evaluate sev…
Since software systems need to be continuously available under varying conditions, their ability to evolve at runtime is increasingly seen as one key issue. Modern programming frameworks already provide support for dynamic adaptations. However the high-variability of features in …
