| Abstract | Even for small programs, the input space is huge - often unbounded. Partition testing divides the input space into disjoint equivalence classes and combinatorial testing selects a subset of all possible input class combinations, according to criteria such as pairwise coverage. The down side of this approach is that the partitioning of the input space into equivalence classes (input classification) is done manually. It is expensive and requires deep domain and implementation understanding. In this paper, we propose a novel approach to classify test inputs and their dependencies automatically. Firstly, random (or automatically generated) input vectors are sent to the system under test (SUT). For each input vector, an observed "hit vector" is produced by monitoring the execution of the SUT. Secondly, hit vectors are grouped into clusters using machine learning. Each cluster contains similar hit vectors, i.e., similar behaviors, and from them we obtain corresponding clusters of input vectors. Input classes are then extracted for each input parameter straightforwardly. Our experiments with a number of subjects show good results as the automatically generated classifications are the same or very close to the expected ones. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
