Abstract Programmers tasked with the fixing of a bug prefer working on a minimal test case where every single bit is needed to reproduce the failure. However, cutting off the excess parts of a potentially large test case can be a tedious and time-consuming task if performed manually, which has led to the research and development of automated test case reduction techniques. The decade-old Hierarchical Delta Debugging (HDD) algorithm targets structured test inputs, parses them with the help of grammars and applies the minimizing Delta Debugging algorithm to the built trees. We have investigated this algorithm and its implementation, and propose improvements in this paper to address the found shortcomings. We argue that using extended context-free grammars with HDD is beneficial in several ways and the experimental evaluation of our modernized HDD implementation, called Picireny, supports the outlined ideas: the reduced outputs are significantly smaller (by circa 25â 40%) on the investigated test cases than those produced by the reference HDD implementation using standard context-free grammars. These results, together with the technical improvements that ease the use of the modernized tool, can hopefully help spreading the adaptation of HDD in practice. .

About National Digital Library of India (NDLI)
NDLI logo

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
