| Abstract | A trend in software testing is reducing the size of a test suite while preserving its overall quality. Given a test suite and a set of requirements covered by the suite, test suite reduction aims at selecting a subset of test cases that cover the same set of requirements. Even though this problem has received considerable attention, finding the smallest subset of test cases is still challenging and commonly-used approaches address this problem only with approximated solutions. When executing a single test case requires much manual effort (e.g., hours of preparation), finding the minimal subset is needed to reduce the testing costs. In this paper, we introduce a radically new approach to test suite reduction, called FLOWER, based on a search among network maximum flows. From a given test suite and the requirements covered by the suite, FLOWER forms a flow network (with specific constraints) that is then traversed to find its maximum flows. FLOWER leverages the Ford-Fulkerson method to compute maximum flows and Constraint Programming techniques to search among optimal flows. FLOWER is an exact method that computes a minimum-sized test suite, preserving the coverage of requirements. The experimental results show that FLOWER outperforms a non-optimized implementation of the Integer Linear Programming approach by 15-3000 times in terms of the time needed to find an optimal solution, and a simple greedy approach by 5-15% in terms of the size of reduced test suite. . |

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.
