Large part of software development is fixing errors, to improve software quality and customer satisfaction. Developers spent 60-80% of their time on searching for relevant code files to fix.
In the context of doctoral research at the Open University in London, we invented a completely new search algorithm. It suggests the likely files to fix an error with enormous efficiency, leading to:
- reduce time and cost to correct errors, by automatically adding the suggestions to the error report;
- build confidence and improve productivity of new or outsourced staff not familiar with the codebase;
Our approach is fast, light-weight and simple and yet outperforms other approaches by listing at least one faulty file among the top 10 suggested.
Average hit rates:
- 1 out 1: 44%
- 1 out of 5: 69%
- 1 out of 10: 76%
We are looking for industrial collaborations partners.
- Our tool is the only one commercially available in the industry.
- Extendable to other programming languages, besides Java.
- Enabled for professional workflows and tools, e.g. bug tracking systems, continuous integration tools, IDEs.
