Random Generation of Test Inputs for Implicitly Defined Subdomains

Content Provider ACM Digital Library
Author Coppit, David Murphy, John A.
Abstract In traditional random testing, samples are taken from the set of all possible values for the input types. However, for many programs testing effectiveness can be improved by focusing on a relevant subdomain defined implicitly by the program behavior. This paper presents an algorithm for identifying and randomly selecting inputs from implicitly defined subdomains. The algorithm dynamically constructs and refines a model of the input domain and is biased toward sparsely covered regions in order to accelerate boundary identification and uniform coverage. This method has several desirable qualities: (1) it requires no knowledge of the source code of the software being tested, (2) inputs are selected from an approximately uniform distribution across the subdomain, and (3) algorithmic running time overhead is negligible. We present the requirements for a solution and our algorithm. We also evaluate our solution for both an artificial model and a real-world aircraft collision-avoidance program.

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.
