TECH TEST in Elixir

Question

How to test

git clone https://github.com/GishaJamesB/tech-test-elixir
cd tech-test-elixir
mix test

How to test with new values

iex -S mix
product =
      [
        %{quantity: 1, name: "imported bottle of perfume", price: 27.99},
        %{quantity: 1, name: "bottle of perfume", price: 18.99},
        %{quantity: 1, name: "packet of headache pills", price: 9.75},
        %{quantity: 1, name: "imported box of chocolates", price: 11.25}
      ]
Tax.display_tax(product)

Currently you would be able to test these products only

imported box of chocolates
imported bottle of perfume
book
packet of headache pills
music cd
chocolate bar
bottle of perfume

But in real applications, you can save the products in a database , categorise it , update the product list etc.
