PROG Exercise: Brush up, Student

In this exercise you must brush up some of your knowledge from 1st and 2nd semester.

You must program a class Student, Unit test the class, and finally document the class.

Getting started

Make a new project in Visual Studio. Type: "Class Library (Portable)".

Class Student

Make a class Student with properties like

• Name, at least 2 characters
• Address, not null
• Semester, 1 <= semester <= 8
• Gender, Enum with values Male and Female

Your class probably needs a constructor to deal with the invariants (requirements) mentioned.
Avoid duplicate code!

Unit test the class Student

Your unit test must have a good coverage.

Document the class Student

Document your class Student using /// (triple slash comments).

Document all public parts of your class.

Class Teacher

Make another class Teacher with properties like

• Name, at least 2 characters
• Address, not null
• Salary, salary >= 0
• Gender, Enum with values Male and Female

Refactor: Superclass

The classes Student and Teacher has a lot in common.

Put the common stuff (properties and methods) in a common superclass Person.

Run the tests after the refactoring.

Extras (if you have extra time...)

Override methods from class Object

• ToString()
• Equals(...)
• GetHashCode()

Extract an interface IStudent from the Student class. Use the interface in your test - and maybe elsewhere.

Extra extra (if you want to try something really interesting ...)

Make another class Student2 using CodeContracts.

Introduction to CodeContracts.

Use the same/similar Unit test as in the first part of this exercise.
