| Abstract | In dynamically typed programming languages, type errors can occur at runtime. Executing the test suites that often accompany programs may provide some confidence about absence of such errors, but generally without any guarantee. We present a program analysis that can check whether a test suite has sufficient coverage to prove a given type-related property, which is particularly challenging for program code with overloading and value dependent types. The analysis achieves a synergy between scalable static analysis and dynamic analysis that goes beyond what can be accomplished by the static analysis alone. Additionally, the analysis provides a new coverage adequacy metric for the completeness of a test suite regarding a family of type-related properties. Based on an implementation for Dart, we demonstrate how such a hybrid static/dynamic program analysis can be used for measuring the quality of a test suite with respect to showing absence of type errors and inferring sound call graph information, specifically for program code that is difficult to handle by traditional static analysis techniques. . |

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.
