Run npm start from the root directory. Use postman or some other HTTP tool to send a GET request to localhost:8080/cart with a JSON body following this pattern

{
  "cart": {
    "reference": "2d832fe0-6c96-4515-9be7-4c00983539c1",
    "lineItems": [
      { "name": "Peanut Butter", "price": "39.0", "collection": "BEST-SELLERS" },
      { "name": "Banana Cake", "price": "34.99", "collection": "DEFAULT" },
      { "name": "Cocoa", "price": "34.99", "collection": "KETO" },
      { "name": "Fruity", "price": "32", "collection": "DEFAULT" }
    ]
