Additional Exercises

1. Project -- Draft Specifications: In class, we outlined some features that might be useful in a program or package that would allow students to test their Scheme programs and to submit their programs to their instructor.
   
   Working individually or in groups of 2 or 3, write a detailed list of desired features for such a program.
   
   These specifications should be written from the users' perspective. Some questions to address are:
   
   
   • What should a user do to run the program (either in a terminal window or on the Web, if desired)?
   • What information should a user supply for each feature, and what information should be returned by the program?
   • How are test cases entered into the system, and to what extent are the test cases secret?
   • In testing by the package, what constitutes a correct solution (e.g., should the format of the output matter, should labeling of output matter, should the order of answers matter, etc.)?
   • Suppose a program goes into an infinite loop during its execution of a test case. How should this be detected, and how should the user be notified? (Note: Computer Science theory indicates that it is impossible to detect all infinite loops, so detection might require a time-out feature, or the testing program might just loop forever.)
   • For testing, how should results of the automated test cases be reported?
   • How should Scheme programs be submitted to the instructor by the user?
   • Presumeably, the instructor would see both the program and the results of the testing. Should other cases be allowed?
