TDD Lab

Lab Objectives

• Practice class brainstorming
• Use TDD to implement Library classes

Brainstorm Classes

In small groups, review the requirements below. Brainstorm the classes and their attributes and methods that we would need to implement the functionality.

Library

We need to be able to create a library that has books and patrons.

A Patron should have a name and phone number.

A Book should have a title, author, and a patron (the patron will be null if the book is not checked out).

The library should be able to tell us which books are NOT checked out.

Stretch Goal: 
We would like the library to tell us which books a given patron has checked out.

Be ready to share your brainstorm! As a cohort, we will develop one class diagram that we will use to build our tests.

Build Tests

Individually

1. Create a new Console Application called Library.
2. Create the tests for the class diagram we created above.

In Small Groups

1. Review the tests that each member created. Ask questions, and reach out to your instructor for help, if needed!

Implement Classes

Before we implement these classes, let’s brainstorm some ideas for how to approach writing these classes.

Individually

1. Implement the classes, using your tests to guide the implementation.

In Small Groups

1. Review your implemented classes - remember that there are multiple ways to accomplish the same goals!
