In today’s modern software applications, developers face the daunting task of sifting through numerous files and millions of lines of code to find and correct faults, a process known as debugging. This manual search for faults can consume a significant amount of developers’ working time, with studies suggesting that it can account for between 30 and 90% of the total development time.
Birgit Hofer and Thomas Hirsch from the Institute of Software Technology at Graz University of Technology have developed a groundbreaking solution to expedite the debugging process. By leveraging existing natural language processing methods and metrics, they have created a system that streamlines the identification of faulty code, making debugging more efficient and effective.
The researchers began by conducting surveys among developers to pinpoint the most time-consuming aspects of debugging. They discovered that the real challenge lies in locating faults within the code, rather than in the actual process of fixing them. Armed with this insight, they set out to devise a solution that could scale to applications with extensive amounts of code.
While model-based approaches have been successful in small-scale programs, they fall short when dealing with larger applications due to the exponential increase in computing effort. Hofer and Hirsch’s approach, on the other hand, represents software properties numerically, allowing for efficient analysis of large code bases without a significant spike in computational resources.
The system developed by the researchers begins with a bug report submitted by testers or users, detailing the observed failure and relevant information about the software environment. By combining natural language processing and metrics, the system analyzes the codebase to identify sections that align with the bug report, presenting developers with a ranked list of files likely responsible for the issue.
By streamlining the debugging process, the system enables developers to swiftly locate and address bugs, minimizing the time spent on debugging and freeing up resources for new feature development. Hofer emphasizes the importance of optimizing developers’ time, highlighting the costliness of ineffective debugging practices.
While the debugging system is currently accessible through GitHub, the researchers aim to further refine and tailor the system to meet the specific needs of individual companies. By laying a solid foundation for commercial application, they have opened up new possibilities for improving debugging processes in the software development industry.
