Test Yourself on Ruby Object Model

Introduction

Our previous post looked at defining private methods inside ruby class methods. While writing that post I came to the realisation that my understanding of the ruby object model was somewhat deficient.

I decided to brush up on my knowledge of the subject (see References), and I thought this might be another good opportunity for a short quiz, allowing readers to test themselves on this important topic.

Have a go at the short quiz below to see how well you know the ruby object model.
