Brewery Design Problem

• The brewery application manages physical inventory, a library of beer recipes, and production of beer.
• The production system supervises the creation, movement and bottling of beer.
• Beer is made according to a recipe which specifies ingredients and amounts.
• Ingredients are mixed in a mixing vat to create a batch of beer. After a batch is mixed, it is moved to a fermenting vat, where readings of its specific gravity will be taken daily.
• While fermenting, beer temperature will be monitored and kept within a tolerance of the temperature as specified in a recipe.
• After it has finished fermenting, beer is moved to another vat to settle, then moved again to a bottling vat where it is bottled on an external bottling line.
• The brewery includes a network of interconnected pipes and vats, an inventory of ingredients, a collection of recipes, and batches of beer both in production and already bottled.

Feature: Summing numbers
  In order to understand the gherkin syntax
  As someone new to cucumber
  I want a simple example

  Scenario: Summing two positive numbers
    Given the first number is 1
    And the second number is 2
    When I sum the numbers
    Then the answer is 3

Week 1 Homework

• Complete the ruby koans
• Use RSpec to test-drive a solution to either:
  • Bowling Kata, or
  • Harry Potter Kata
• Write a 10 minute presentation about the topic card you pick
• BONUS: clone Corey Haines' [practice repo] [1], and use it to help you complete a Game of Life solution.
  • You will need to research [cucumber] [2] and [bundler] [3]
• Use cucumber and rspec to help guide your code
