Notes From "Practical Object-Oriented Design In Ruby" by Sandi Metz

Chapter 1 - Object Oriented Design

The purpose of design is to allow you to do design later, and it's primary goal is to reduce the cost of change.

SOLID Design:

  • Single Responsibility Principle: a class should have only a single responsibility
  • Open-Closed Principle: Software entities should be open for extension, but closed for modification (inherit instead of modifying existing classes).
  • Liskov Substitution: Objects in a program should be replaceable with instances of their subtypes without altering the correctness of that program.
  • Interface Segregation: Many client-specific interfaces are better than one general-purpose interface.

MiniTest::Spec

use must for positive expectations and wont for negative expectations.

  • must_be | list.size.must_be :zero?
  • must_be_close_to | subject.size.must_be_close_to 1,1
  • must_be_empty | list.must_be_empty
  • must_be_instance_of | list.must_be_instance_of Array
  • must_be_kind_of | list.must_be_kind_of Enumerable
You can’t perform that action at this time.
