Software Research

At Zeller's group at CISPA, we do software research. We create tools and techniques that help developers build better software – by automatically testing, analyzing, and debugging its code and its development process. Our research projects involve generating software tests, automated debugging and repair, analyzing mobile systems, analyzing user interfaces, and more – all areas in which we continue to shape academic research and industrial practice.

CURRENT PROJECTS

Our research projects involve generating software tests, automated debugging and repair, analyzing mobile systems, analyzing user interfaces, and more; see our papers below for details. Our solutions typically apply and combine several techniques including dynamic analysis, static analysis, specification mining, test generation, natural language processing, machine learning, and formal languages.

My largest project these days is The Fuzzing Book—an interactive textbook on test generation (“fuzzing”) techniques. You can execute and edit the code right in your browser.
