Environmental Variations of Software Features: A Logical Test Cases' Perspective

An important activity of requirements-based testing (RBT) is to generate logical test cases to verify whether the requirements have been implemented correctly. A recent RBT method uses linguistic clues based on actions and conditions to develop logical test cases. In this paper, we extend this RBT method to analyze the feature tests written by a Web application's developers, as well as to test the features released by the vendors of a proprietary software system. The results confirm the applicability and effectiveness of the linguistic clues in identifying environmental variations, thereby showing the potentials to improving the test coverage and revealing bugs.
