Assignment:

Overview- You are required to document, test and refactor an existing application. You will be given a copy of an existing C# application which is responsible for taking bookings for a cruise ship, this application is badly in need of refactoring and even a casual viewing of the source code reveals many examples of the "code smells" discussed by Fowler.

Learning Outcomes-

Knowledge:

Explain the significance of detailed project planning and control, good communication and documentation and the use of appropriate tools in order to provide a quality product;

Discriminate between software engineering and programming, and thus the distinction between a software configuration and a program;

Skills:

Analyse source code and develop comprehensive unit test suites

Operate CASE software to document the design of a piece of software

Apply refactoring to identify poor programming practice in existing source code and improve its structure and readability

Assessment Details-

You are required to document, test and refactor an existing application. You will be given a copy of an existing C# application which is responsible for taking bookings for a cruise ship, this application is badly in need of refactoring and even a casual viewing of the source code reveals many examples of the "code smells" discussed by Fowler.

There are eight types of cabin which may be booked. Standard costs are as follows:

• Balcony Suite ($5000 per cabin)
• Suite ($4000 per cabin)
• Deck 3 - Outside Twin ($3500 per cabin)
• Deck 2 - Outside Twin ($3400 per cabin)
• Deck 1 - Outside Twin ($3300 per cabin)
• Deck 3 - Inside Twin ($3400 per cabin)
• Deck 2 - Inside Twin ($3300 per cabin)
• Deck 1 - Inside Twin ($3200 per cabin)

Requirements

• Report detailing any "code smells" present in the code and how you intend to refactor them out of the code

• A refactored version of the system eliminating all identified code smells

• A class diagram illustrating the initial code and another class diagram illustrating the final refactored code (including all relevant dependencies)

• A sequence diagram illustrating how the final refactored system processes a new booking

• Extensive NUnit tests for methods SetupShip and BookPassage in the FedUniCruises class

• Add a loyalty rewards system. People who are bronze members of the loyalty rewards program receive a 5% discount on all bookings, people who are silver members receive 7.5% discount, while gold members receive 10% off the cost of their bookings.

• Add a platinum membership to the loyalty rewards program which entitles the holder to 50% off the cost of booking on decks 1, 2 and 3 and 25% off the cost of bookings for all suites.
