Iteration 1 - Ingredient and Pantry

There are 4 Possible Points in Iteration 1:

Ingredient Creation - including all attr_readers
Pantry Creation - including all attr_readers
Pantry #stock_check
Pantry #restock

Use TDD to build an Ingredient and a Pantry class that respond to the interaction pattern below:

pry(main)> require './lib/ingredient'
# => true

pry(main)> require './lib/pantry'
# => true

pry(main)> ingredient1 = Ingredient.new({name: "Cheese", unit: "oz", calories: 50})
# => #<Ingredient:0x007fe6041273d8...>

pry(main)> ingredient1.name
# => "Cheese"

pry(main)> ingredient1.unit
# => "oz"

pry(main)> ingredient1.calories
# => 50

pry(main)> ingredient2 = Ingredient.new({name: "Macaroni", unit: "oz", calories: 200})
# => #<Ingredient:0x007fd88582ed98...>

pry(main)> pantry = Pantry.new
# => #<Pantry:0x007fd8858863b8...>

pry(main)> pantry.stock
# => {}

pry(main)> pantry.stock_check(ingredient1)
# => 0

pry(main)> pantry.restock(ingredient1, 5)

pry(main)> pantry.restock(ingredient1, 10)

pry(main)> pantry.stock_check(ingredient1)
# => 15

pry(main)> pantry.restock(ingredient2, 7)

pry(main)> pantry.stock_check(ingredient2)
# => 7

Iteration 2 - Recipe and CookBook

There are 4 possible points in Iteration 2:

Recipe and CookBook Creation - including all attr_readers
Recipe #add_ingredient

For the add_ingredient method, the first argument is an Ingredient, and the second argument is the amount of the ingredient required for the Recipe.

Recipe #ingredients
CookBook #add_recipe

Use TDD to build a Recipe class and a CookBook class that respond to the following interaction pattern.

pry(main)> require './lib/ingredient'
# => true

pry(main)> require './lib/recipe'
# => true

pry(main)> require './lib/cook_book'
# => true

 pry(main)> ingredient1 = Ingredient.new({name: "Cheese", unit: "C", calories: 100})
# => #<Ingredient:0x007fe8438c7a70...>

 pry(main)> ingredient2 = Ingredient.new({name: "Macaroni", unit: "oz", calories: 30})
# => #<Ingredient:0x007fe843857f40...>

pry(main)> recipe1 = Recipe.new("Mac and Cheese")
# => #<Recipe:0x007fe84383d000...>

pry(main)> recipe1.name
# => "Mac and Cheese"

pry(main)> recipe1.ingredients_required
# => {}

pry(main)> recipe1.add_ingredient(ingredient1, 2)

pry(main)> recipe1.add_ingredient(ingredient1, 4)

pry(main)> recipe1.add_ingredient(ingredient2, 8)

pry(main)> recipe1.ingredients_required
# => {#<Ingredient:0x00007fd7811553c8...> => 6, #<Ingredient:0x00007fd78110b0e8...> => 8}

pry(main)> recipe1.ingredients
# => [#<Ingredient:0x007fe8438c7a70...>, #<Ingredient:0x007fe843857f40...>]

pry(main)> recipe2 = Recipe.new("Cheese Burger")

pry(main)> cookbook = CookBook.new
# => #<CookBook:0x00007faae6a42228 @recipes=[]>

pry(main)> cookbook.add_recipe(recipe1)

pry(main)> cookbook.add_recipe(recipe2)

pry(main)> cookbook.recipes
# => [#<Recipe:0x00007faae69c9698...>, #<Recipe:0x00007faae692a110...>]

Iteration 3

There are 4 possible points in Iteration 3:

Recipe #total_calories

The total_calories method should sum the calories of each ingredient. The calories for each ingredient can be calculated by multiplying the calories attribute of the Ingredient by the amount of the ingredient required for the recipe.

CookBook #ingredients
CookBook #highest_calorie_meal
Pantry #enough_ingredients_for

Use TDD to update your Recipe, CookBook and Pantry classes so that they respond to the following interaction pattern:

pry(main)> require './lib/pantry'
# => true

pry(main)> require './lib/ingredient'
# => true

pry(main)> require './lib/recipe'
# => true

pry(main)> require './lib/cook_book'
# => true

pry(main)> pantry = Pantry.new
# => #<Pantry:0x007fd8858863b8...>

pry(main)> cookbook = CookBook.new
# => #<CookBook:0x00007faae6a42228 @recipes=[]>

pry(main)> ingredient1 = Ingredient.new({name: "Cheese", unit: "C", calories: 100})
# => #<Ingredient:0x00007faae6a207e0...>

pry(main)> ingredient2 = Ingredient.new({name: "Macaroni", unit: "oz", calories: 30})
# => #<Ingredient:0x00007faae69e3cf0...>

pry(main)> recipe1 = Recipe.new("Mac and Cheese")
# => #<Recipe:0x00007faae69c9698...>

pry(main)> recipe1.add_ingredient(ingredient1, 2)

pry(main)> recipe1.add_ingredient(ingredient2, 8)

pry(main)> ingredient3 = Ingredient.new({name: "Ground Beef", unit: "oz", calories: 100})
# => #<Ingredient:0x00007faae6950860...>

pry(main)> ingredient4 = Ingredient.new({name: "Bun", unit: "g", calories: 75})
# => #<Ingredient:0x00007faae694bb80...>

pry(main)> recipe2 = Recipe.new("Cheese Burger")
# => #<Recipe:0x00007faae692a110...>

pry(main)> recipe2.add_ingredient(ingredient1, 2)

pry(main)> recipe2.add_ingredient(ingredient3, 4)

pry(main)> recipe2.add_ingredient(ingredient4, 1)

pry(main)> recipe1.total_calories
# => 440

pry(main)> recipe2.total_calories
# => 675

pry(main)> cookbook.add_recipe(recipe1)

pry(main)> cookbook.add_recipe(recipe2)

pry(main)> cookbook.ingredients
# => ["Cheese", "Macaroni", "Ground Beef", "Bun"]

pry(main)> cookbook.highest_calorie_meal
# => #<Recipe:0x00007faae692a110...>

pry(main)> pantry.restock(ingredient1, 5)

pry(main)> pantry.restock(ingredient1, 10)

pry(main)> pantry.enough_ingredients_for?(recipe1)
# => false

pry(main)> pantry.restock(ingredient2, 7)

pry(main)> pantry.enough_ingredients_for?(recipe1)
# => false

pry(main)> pantry.restock(ingredient2, 1)

pry(main)> pantry.enough_ingredients_for?(recipe1)
# => true

Iteration 4

There are 2 possible points in iteration 4

CookBook #summary

For the summary, ingredients are listed in order of calories. This is the amount of calories that ingredient contributes to the total calories of the recipe, not the amount of calories per single unit of the ingredient.

CookBook #date

Hint: your test will need to be able to pass on any day it is run, not just today.

Use TDD to build a CookBook class that responds to the following interaction pattern.

pry(main)> require './lib/cook_book'
# => true

pry(main)> require './lib/ingredient'
# => true

pry(main)> require './lib/recipe'
# => true

pry(main)> cookbook = CookBook.new
# => #<CookBook:0x00007faae6a42228 @recipes=[]>

pry(main)> ingredient1 = Ingredient.new({name: "Cheese", unit: "C", calories: 100})
# => #<Ingredient:0x00007faae6a207e0...>

pry(main)> ingredient2 = Ingredient.new({name: "Macaroni", unit: "oz", calories: 30})
# => #<Ingredient:0x00007faae69e3cf0...>

pry(main)> recipe1 = Recipe.new("Mac and Cheese")
# => #<Recipe:0x00007faae69c9698...>

pry(main)> recipe1.add_ingredient(ingredient1, 2)

pry(main)> recipe1.add_ingredient(ingredient2, 8)

pry(main)> ingredient3 = Ingredient.new({name: "Ground Beef", unit: "oz", calories: 100})
# => #<Ingredient:0x00007faae6950860...>

pry(main)> ingredient4 = Ingredient.new({name: "Bun", unit: "g", calories: 1})
# => #<Ingredient:0x00007faae694bb80...>

pry(main)> recipe2 = Recipe.new("Burger")
# => #<Recipe:0x00007faae692a110...>

pry(main)> recipe2.add_ingredient(ingredient3, 4)

pry(main)> recipe2.add_ingredient(ingredient4, 100)

pry(main)> cookbook.add_recipe(recipe1)

pry(main)> cookbook.add_recipe(recipe2)

pry(main)> cookbook.summary
# => [{:name=>"Mac and Cheese", :details=>{:ingredients=>[{:ingredient=>"Macaroni", :amount=>"8 oz"}, {:ingredient=>"Cheese", :amount=>"2 C"}], :total_calories=>440}}, {:name=>"Burger", :details=>{:ingredients=>[{:ingredient=>"Ground Beef", :amount=>"4 oz"}, {:ingredient=>"Bun", :amount=>"100 g"}], :total_calories=>500}}]

# The 'date' method should return the date the cookbook is created as "mm-dd-yyyy"
pry(main)> cookbook.date
# => "06-14-2022"
