The brief
Design, implement and test a command-line library management system in Python. Submit your code with a report covering requirements, design, implementation decisions and testing. 2,000 words excluding code, IEEE referencing.
Why this sample works
What a marker would single out, and what to look for as you read.
- Requirements traced through to design and tests
- Class design justified, including what was deliberately left out
- Test plan with normal, boundary and erroneous cases
- Honest evaluation of limitations and next steps

Design and testing report for a Python library management system
1. Introduction
This report documents the design, implementation and testing of a command-line library management system written in Python 3.12. The system allows staff to add and remove books, register members, issue and return loans, and calculate overdue fines. Data persists between sessions in JSON files. The report explains the reasoning behind the main design decisions and provides evidence that the system meets its requirements.
2. Requirements
- FR1: Staff can add, search for and remove books by ISBN, title or author
- FR2: A member may hold a maximum of five loans at once
- FR3: Fines accrue at 20p per day overdue, capped at the book's replacement cost
- NFR1: Invalid input must never crash the program
3. System design
The design separates domain objects from storage and from the user interface. Book, Member and Loan are plain data classes with validation in their constructors. A Library class holds the business rules, such as the loan limit and fine calculation, and depends on a Repository interface rather than on JSON directly. This separation made the rules testable in isolation, since tests use an in-memory repository and never touch the file system [1].
