Teaching Software Testing using Data Structures

Author 1: Ingrid A. Buckley Author 2: Winston S. Buckley

Software testing is typically a rushed and neglected activity that is done at the final stages of software development. In particular, most students tend to test their programs manually and very seldom perform adequate testing. In this paper, two basic data structures are utilized to highlight the importance of writing… Read full abstract & cite →
