Test case prioritization using ant colony optimization

Abstract

Regression testing is primarily a maintenance activity that is performed frequently to ensure the validity of the modified software. In such cases, due to time and cost constraints, the entire test suite cannot be run. Thus, it becomes essential to prioritize the tests in order to cover maximum faults in minimum time. In this paper, ant colony optimization is used, which is a new way to solve time constraint prioritization problem. This paper presents the regression test prioritization technique to reorder test suites in time constraint environment along with an algorithm that implements the technique.
