| Abstract | Researchers have argued that for failure to be observed the following three conditions must be met: 1) the defect is executed, 2) the program has transitioned into an infectious state, and 3) the infection has propagated to the output. Coincidental correctness arises when the program produces the correct output, while conditions 1) and 2) are met but not 3). In previous work, we showed that coincidental correctness is prevalent and demonstrated that it is a safety reducing factor for coverage-based fault localization. This work aims at cleansing test suites from coincidental correctness to enhance fault localization. Specifically, given a test suite in which each test has been classified as failing or passing, we present three variations of a technique that identify the subset of passing tests that are likely to be coincidentally correct. We evaluated the effectiveness of our techniques by empirically quantifying the following: 1) how accurately did they identify the coincidentally correct tests, 2) how much did they improve the effectiveness of coverage-based fault localization, and 3) how much did coverage decrease as a result of applying them. Using our better performing technique and configuration, the safety and precision of fault-localization was improved for 88% and 61% of the programs, respectively. |

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.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
