I added another test to check that discount and tax were working together just to make sure.

The Beginning I’m a big fan of Zoran Horvat’s courses on Pluralsight and I follow him on Twitter. I saw that he posted this kata as a challenge to another person who was arguing against hime about coding paridaims (procedural vs oop vs functional).

I mentioned it to my team and they said they would join me, although we will see if they follow through :)

Ingredients 4 cups coffee concentrate* 4 cups whole milk 1/2 cup caramel syrup Directions Mix coffee concentrate and milk in 1/2 gallon pitcher. Stir in caramel syrup and refrigerate. Pour over ice and enjoy! I use Torani caramel sauce personally. Using that, I calculate 1 cup of the finished mixture is about 205 calories. *Coffee concentrate directions. Make coffee using 1 cup of coffee to 4 cups of water. I do the cold brew method and let it sit overnight.
