Stateless Code

This is the 17th video in the NerdDice create a RubyGem series. In this video, Mike finishes refactoring the specs from the previous videos and then comments out the refresh_seed! method and simulates redoing test-driven development to ensure the specs all fail without the code and pass with it. He refactors longer methods out into…

This is the 16th video in the NerdDice create a RubyGem series. In this video, Mike refactors the specs from the previous video using a module in the spec/support directory and uses RSpec shared examples to avoid multiple expectations in the same “it” block. He also fixes some RuboCop violations from the previous 2 videos.

This is the 15th video in the NerdDice create a RubyGem series. In this video, Mike finishes up writing specs for the other scenarios (seed options, technique option) of the refresh_seed! method.

This is the 14th video in the NerdDice create a RubyGem series. In this video, Mike adds a method to (NerdDice.refresh_seed!) to reset the seed on the random number generators and writes the specs for the no argument (default) scenario.

This is the 13th video in the NerdDice create a RubyGem series. In this video, Mike adds the NerdDice logo to the GitHub repo and adjusts some of the class methods so that the execute_die_roll method is public and directly covered by specs. Also due to the release of Ruby 3, the securerandom gem is…

This is the 12th video in the NerdDice create a RubyGem series. In this video, Mike takes the configuration that was developed in video 10 (Make the gem configurable) and applies it to the total_dice method so that users can specify their preferred random number generation method. We also take this opportunity to refactor repeated…

This is the 11th video in the NerdDice create a RubyGem series. In this video, Mike provides an overview of the pseudo-random number generation options in Ruby (Random.rand(), Kernel.rand(), Random.new(), SecureRandom.rand()) as well as a demonstration of the determined and replayable order of random events if the seed is known.

This is the 10th video in the NerdDice create a RubyGem series. In this video, Mike adds a configuration class to NerdDice, allowing users to supply configuration for different properties of the gem and customize use of it using a common Ruby design pattern.
