Solution Code

##You-Do: Solution 1:

it "has a String for an Name" do
  dog = Dog.new("Rover", 10)
  expect(dog.name).to be_a(String)
end

##You-Do: Solution 2:

it "has a hunger level thats an Integer" do
  dog = Dog.new("Rover", 10)
  expect(dog.hunger_level).to be_a(Integer)
end

##You-Do: Solution 3:

describe "#set_hunger_level" do
  context "when new hunger level" do
    context "is less than 0" do
      it "sets the hunger level to 0" do
        @dog = Dog.new("Rover", 10)
        @dog.set_hunger_level(-1)
        expect(@dog.hunger_level).to eq(0)
      end
    end
    context "is greater than 0" do
      it "sets our hunger level to the new hunger level" do
        @dog = Dog.new("Rover", 10)
        @dog.set_hunger_level(2)
        expect(@dog.hunger_level).to eq(2)
      end
    end
  end
end

Subject:

require "rspec"
