Debugging in modern software applications is a daunting task due to the complexity and sheer volume of code involved. Developers often spend a significant amount of their time manually searching for faults, which can account for up to 90% of the total development time. The process of locating bugs, rather than fixing them, has been identified as a major time waster in software development.
Birgit Hofer and Thomas Hirsch from the Institute of Software Technology at Graz University of Technology have developed a groundbreaking solution to streamline the debugging process. By leveraging natural language processing methods and metrics, they have created a system that can significantly accelerate the identification of faulty code. This system addresses the challenge of narrowing down the search to the right area in the program code, which is a common stumbling block for developers.
Traditional model-based approaches for fault localization are limited by their scalability, as the computing effort increases exponentially with the size of the code. Hofer and Hirsch’s approach, on the other hand, represents software properties in numbers, such as readability and complexity of code. This allows for efficient analysis of large amounts of code, with the computational effort increasing linearly.
The researchers’ system starts with a bug report filled out by testers or users, describing the observed failure and relevant details about the software and system configuration. Using natural language processing and metrics, the system analyzes the code to identify sections that best match the bug report. Developers receive a list of potential files ranked by the likelihood of containing the bug, along with information on the type of fault involved.
By providing developers with targeted information about potential faults, Hofer and Hirsch’s system helps reduce the time spent on debugging and enables faster bug resolution. This is crucial, as the expensive working time of developers is often consumed by bug fixing rather than developing new features. The system aims to optimize this process and make software development more efficient.
While the debugging system is currently available on the “GitHub” platform, further adaptations may be needed to tailor it to specific company requirements. The researchers have laid the foundation for a viable commercial application and are open to collaborating with companies to integrate and implement the system effectively. By combining and enhancing existing approaches, they have created a robust system that can revolutionize the debugging process in software development.
