Impact of Fault-Prone Components on Effective Software Testing: An Industrial Survey

摘要

In a real-time software system, often a small portion of the components holds the major operations of the system. Thus, the rate of failure of those portions is high, which leads to major loss to the system. In order to develop cost-effective and high-quality software systems, those fault-prone components must be identified and tested rigorously. This paper analyzes the industrial questionnaire survey with a focus on the significance of early identification of fault-prone components within a system and importance of the fault-prone components-based testing. From the survey results, it has been inferred that, fault-prone components can be identified using software models, formal specifications and appropriate metrics and measures; which would, in turn, reduce the cost of defect and testing. Furthermore, the present study endeavours to investigate as to how far research efforts are essential in providing guidelines in the adoption of fault-prone components-based development, thus improving the quality of software development.
