Automated Testing of Unix Command-line and Scripting Skills

摘要

This paper describes the use of LinuxGym - software which assists a student's learning of Linux scripting, from directory listing to advanced Perl programming. The software randomly generates new tasks for each student and is used to check their attempts for the purpose of both formative and summative assessment. While the tasks are smaller than an assignment-sized software development project, they are nevertheless actual Linux usage (rather than a simulation) and enable a large number of practice and feedback loops, rather than just one or two large submissions. As a result, there has been a far lower failure rate and student surveys indicate a high level of motivation and satisfaction with its use.
