E1506: Refactoring, testing and new features related to “users”

Overview

Code refactoring

Refactoring is a disciplined technique for restructuring an existing body of code, altering its internal structure without changing its external behavior<ref>Refactoring</ref>. Refactoring adds to the value of any program that has at least one of the following shortcomings<ref>Benefits of Code Refactoring Michael Hunger. Oct. 25, 2000</ref>:

• Programs that are hard to read are hard to modify;
• Programs that have duplicate logic are hard to modify;
• Programs that require additional behavior that requires you to change running code are hard to modify;
• Programs with complex conditional logic are hard to modify.
  

Rspec

RSpec is a behavior-driven development (BDD) framework for the Ruby programming language, inspired by JBehave. It contains its own mocking framework that is fully integrated into the framework based upon JMock. The framework can be considered a domain-specific language (DSL) and resembles a natural language specification<ref>Rspec</ref>.

O-O Design Principles

Object oriented design a process of planning a software system where objects will interact with each other to solve specific problems. Though an Object oriented language provides us with highly useful and important programming concepts like Inheritance, Polymorphism, Abstraction and Encapsulation which definitely makes the code more efficient, it is equally important to have the knowledge of using them in the code. Object Oriented Design Principles are core of OOPS programming<ref>[1] Javin Paul. Blogspot. March 3, 2012</ref>. It is important to know these design principles, to create clean and modular design. There are a number of design principles that help us produce a more understandable and elegant code.
