Assignment 7 – Implementation

Purpose

The purpose of this assignment is to continue with our design modeling of the ITOT Case Study.

 

 For the Manage Shopping Cart use case, you will create a test scenario, and two test cases.  You will also create a persistent UML class diagram and SQL statements for ShoppingCart and ShoppingCartItem.  Finally you will map your domain classes ShoppingCarat and ShoppingCartItem to Java statemens.  Use you domain class diagram with attributes and operations.

 You will create two test cases following the format described in your design specification.  In testing, test cases are developed first and then tested later by a different team. You will not be able to exercise your test cases (so you won’t have Actual Results) but you can create the test case. You will also  create SQL statements including constraints forShoppingCart and ShoppingCartItem.  You will also create sample Java statements for ShoppingCart and ShoppingCartItem design classes.

In this assignment you complete the following sections in your Design Specification

Sections 6, 6.1, 6.2, 6.2.1, 6.3, 6.3.1 on test cases, Sections 7, 7.1, 7.1.2, 7.2, 7.2,1 on SQL, and Sections 8, 8.1, 8.2  on Java. 

 

 Instructions

1.  Review the Quick Resources listed at the end of this assignment.

Test Scenario and Test Cases

2.  Section 6, 6.1. You will identify and document one test scenario (name and description) based on the Manage Shopping Cart use case and complete Sections 6 and 6.1 in your design specification.  A test scenario is not the same thing as a test case!

3.  You will create and discuss two test cases for your scenario above for Manage Shopping Cart including test Case Name, Description, Prerequisites, Steps, Input, Expected Result, Actual Result, Status. The steps of the test case must be numbered!

    3.1  You will create Test Case 1 based on your scenario for Manage Shopping Cart and add it in the table format in Section 6.2 of your design specification.

       3.1.1  You will add a discussion of Test Case 1 to Section 6.2.1 in your design specification. 

    3.2  You will create Test Case 2 based on your scenario for Manage Shopping Cart  and add it in the table format in Section 6.3 of your design specification.

      3.2.1  You will add a discussion of Test Case 2 to Section 6.3.1 in your design specification. 

4.  Your entity (persistent) classes will most likely become tables in a relational database. In database design, we would follow normalization and functional decomposition guidelines to normalize our entities (classes) into valid relations.  Then we would create SQL (Structured Query Language) statements to create the tables and add constraints. After that, we could populate our tables with data. We will assume our classes are normalized for this exercise.

Persistent Class Diagram

    4.1  Create a persistent UML class diagram (without operations) of persistent data.  You most likely already have this. Make certain that you include ShoppingCart and ShoppingCartItem. Designate primary and foreign keys.  Add this to Section 7.1 in your design specification.

    4.2  Include a discussion of your persistent class diagram in Section 7.1.2 in your design specification. 

SQL Statements for ShoppingCart and ShoppingCartItem

5.  You will use two classes (ShoppingCart and ShoppingCartItem) from your persistent UML class diagram and create the SQL statements to implement the tables and constraints. You will need to include primary key and foreign key constraints. Add the SQL Statements to Section 7.2 of your design specification.    

5.1  Include a discussion of your SQL statements in Section 7.2.1 in your design specification

6.  Complete Section 7 of your design specification.

Java for ShoppingCart and SoppingCartItem

7.  Using Chapter 18 examples in your textbook or your resources below, create Java statements for ShoppingCart and ShoppingCartItem detailed design classes.  Note that ShoppingCart and ShoppingCartItem have a composition type of part whole relationship. See the Engine and Piston example at 

https://coderanch.com/t/443002/java/Java-Coding-UML-Aggregation-Composition

.  Add them to Section 8.1 of your design specification and complete Section 8 and 8.2 discussion.  You need to map the attributes and methods.

 

Submission Directions

1.   When you submit your Word file, use your name as part of the file name, e.g., ENTD321Assignment7_FirstNameLastName
