| Abstract | In continuous integration development environments, software engineers frequently integrate new or changed code with the mainline codebase. This can reduce the amount of code rework that is needed as systems evolve and speed up development time. While continuous integration processes traditionally require that extensive testing be performed following the actual submission of code to the codebase, it is also important to ensure that enough testing is performed prior to code submission to avoid breaking builds and delaying the fast feedback that makes continuous integration desirable. In this work, we present algorithms that make continuous integration processes more cost-effective. In an initial pre-submit phase of testing, developers specify modules to be tested, and we use regression test selection techniques to select a subset of the test suites for those modules that render that phase more cost-effective. In a subsequent post-submit phase of testing, where dependent modules as well as changed modules are tested, we use test case prioritization techniques to ensure that failures are reported more quickly. In both cases, the techniques we utilize are novel, involving algorithms that are relatively inexpensive and do not rely on code coverage information -- two requirements for conducting testing cost-effectively in this context. To evaluate our approach, we conducted an empirical study on a large data set from Google that we make publicly available. The results of our study show that our selection and prioritization techniques can each lead to cost-effectiveness improvements in the continuous integration process. . |

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.
