Finding min-repros in database software

Content Provider ACM Digital Library
Author Bruno, Nicolas Nehme, Rimma V.
Abstract Testing and debugging database system applications is often challenging and time consuming. A database tester (or DB tester for short) has to detect a problem, determine why it happened, set up an environment to reproduce it, and then create a fix to resolve the problem. In many cases, problems appear in complex scenarios, and thus the setup to reproduce a problem may be large and difficult to understand. This makes the task of finding the root cause of a problem very challenging. As a consequence, a very arduous task for a DB tester is finding a min-repro -- a process of weeding out irrelevant inputs and finding the simplest way to reproduce a problem. Currently, a great deal of searching for minrepros is carried out manually using non-database-specific tools, which is both slow and error-prone. In this paper, we present a system designed to ease and speed up searches for minrepros in database-related products. The min-repro system employs several effective tools, including: the novel simplification transformations, the high-level language for creating custom scripts and automation, the record-and-replay functionality, and the visualization of results and the search space. In addition to the standard application mode, the min-repro system can be interacted with in the game mode. The latter can provide an intrinsically motivating environment for developing successful search strategies, which can be data-mined and generalized into search patterns and used as recommendations for DB testers.

About National Digital Library of India (NDLI)
NDLI logo

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.
