Online MusicCD Store MSE Project Presentation II Presented by: Reshma Sawant Major Professor: Dr. Daniel Andresen

Phase II Presentation Outline  Action Items from Phase I  Architecture Design  Formal Requirement Specification  Formal Inspection Checklist  Test Plan  Questions

Action Items from Phase I 1) Additions to Vision Document  Description of “Pagination” feature on Product.aspx Web Page  Specify Browser requirements – IE or Mozilla Firefox  More flexibility when searching a Music CD  Search by AlbumName, Artist, Style, Price range

Action Items from Phase I 2) Goals for Performance Testing (Test Plan)  Tests to be performed  Different environments for testing  Expected load (number of concurrent users and requests)

Additional Functionality 1) “Song Recommendation” feature for User Actor  Based on Purchase History of past Users  Order details of each product will be saved in order table

Song Recommendation Based on Purchase History

Additional Functionality 1) “Song Recommendation” feature for Customer Actor  Based on data gathered from other users with similar preferences  Data Mining Technique called Case-Based Reasoning Process  Retrieve  Reuse  Revise  Retain

Song Recommendation Based on similar preferences of other users

Additional Functionality 2) “Manage Orders” functionality for Administrator  View User Order History  Update Order status to completed, uncompleted, verified, unverified  Delete Orders having status uncompleted and unverified

Formal Requirement Specification Constraints  The UserId for each user must be unique  Products are not shared across Genres  Price of the product should be positive  Each Shopping Cart belongs to exactly one user  Shopping Cart exists only when it contains a cart item  Each Order belongs to exactly one user  Each Order must have a status as completed, uncompleted, verified, unverified.

 The symbols used in Class diagrams conform to UML standards.  The classes in the Class diagram have a corresponding description provided in Architecture Design Document  Classes in the Architecture Design correspond to the classes in USE Model Inspection Checklist

 The multiplicities in the USE Model are reflected in Class diagram  The attributes in the USE Model are compatible with attributes of the corresponding class diagram  All the requirements on Software Requirement Specification have been covered in Architecture Design document  Sequence Diagram matches Class diagram

Test Plan  Unit Testing using NUNIT tool  Performance Testing using JMeter tool

Test Plan – Sample UNIT Test Case Purpose: Test that clicking Update Quantities will update the cart summary accordingly. Incorrect Input: Negative input number or input other than integer number, input number greater than ‘max’ count specified in “Quantity” field Pass criteria: An appropriate message should be displayed and information should not be updated in Shopping Cart.
