Emphasizing Software Quality in Undergraduate Programming Laboratories

对于使用和开发软件的组织来说，软件质量正成为一个日益重要的问题。教育工作者需要在本科计算机科学教育中强调质量为基础的理念。这个项目概述了一种新的方法，称为对抗性测试，它鼓励学生开发高质量的程序并为该程序开发测试用例。这种方法可以很容易地结合到任何涉及大量编程实验室练习的课程中。在对抗性测试中，学生受到自然竞争本能的驱使，试图揭露同学解决方案中的错误，同时针对同学提出的揭示错误的测试用例进行辩护。这项技术使学生更深入地了解软件中的错误来源，以及构建可靠、健壮的软件的不同技术。该项目使用基于万维网的测试服务器，该服务器管理与课程和学生相关的程序和测试数据，执行测试，并累积和报告测试结果。对抗性测试被引入到计算机科学课程的五门必修课和两门选修课中。在这些课程的背景下，对让学生用对抗性测试解决编程实验室练习的短期和长期效果进行了实证研究。*

Software quality is becoming an increasingly important issue to organizations that use and develop software. Educators need to emphasize quality as a foundation concept in undergraduate computer science education. This project outlines a novel approach, called adversarial testing, that encourages students to develop high quality programs and to develop test cases for that program. This approach can be easily incorporated into any course that involves significant programming laboratory exercises. In adversarial testing, students are motivated by natural competitive instincts to attempt to expose faults in their classmates' solutions while at the same time defending against fault-revealing test cases produced by their classmates. This technique leads students to a deeper understanding of the sources of faults in software and of different techniques for building reliable, robust software. This project uses a World Wide Web-based testing server that manages the program and test data associated with courses and students, performs the tests, and accumulates and reports the results of testing. Adversarial testing is introduced into five required and two elective courses in the computer science curriculum. In the context of these courses, both the short-term and long-term effects of having students solve programming laboratory exercises with adversarial testing is studied empirically. *
