MOSS

Current SIU ProblemCurrent SIU Problem

• Believe it or not, there are some CS students at SIU that do NOT code their own programming assignments.

• Instructors need a way to check multiple programming assignments for similarity.

• Doing this by hand takes way too long.

• There exists an application hosted by U.C. at Berkeley called MOSS (Measure Of Software Similarity) that compares programs, but currently, the process of requesting MOSS services is not convenient.

MOSS

Current MOSS ProblemsCurrent MOSS Problems

• Command line interface to run a Perl script for UNIX.

• Not integrated with SIU student drop boxes.

• No GUI or MOSS I/O automation.

• 2 week lifetime of MOSS reports.

• No locality of MOSS reports.

MOSS

Requirements AnalysisRequirements Analysis

MOSS

Requirements AnalysisRequirements Analysis

• Client interview sessions.

• Perl script analysis and functional decomposition.

• Prototype of MOSS service requests.

• Subsequent review of MOSS reports.

• Constant review with client.

Test Plan

The Lead Tester is responsible for developing a system of testing which includes:

• Lo-fi and Hi-fi prototyping at the early stages of development.

• Making sure that all features agreed upon are in the application.

• Debugging and Testing of all Routines.

MOSS

Test Plan (cont.)

Documentation will include:

• Why the test is being conducted

• How the test will be conducted

• Where the test will be conducted

• When the test will be conducted

• Who will conduct the test

Every test will be documented

MOSS

Deployment Plan

• Installation on CS Dept. Windows 2000 Server

• Entire CodeCop application will be in one place

• Training

• Client and other instructors will need to learn the UI

• Student Web Interface (optional per Instructor)

MOSS

Deployment Plan (cont.)

• Operation (continued)

• CodeCop System will need very little maintenance

• Requires server to be up and running

• Requires server to maintain a connection to network
