Softwares requiered

• Docker

Assumptions

• Multiple promotions cannot be applied to the same product
• Product in the follow format:

[
  {
    "code":"B",
    "price_cents":1000,
    "promotion":{
      "type":"combination",
      "product_code":"E",
      "price_cents":0
    }
  },
  {
    "code":"C",
    "price_cents":125,
    "promotion":{
      "type":"group",
      "quantity":6,
      "price_cents":600
    }
  }
]

• All keys for a product should be present in the product data, else the code will throw an exception.
• Current output price will be in USD.

To use a new sample data

Please look at bin/process.rb file, you can change the sample_products.json file to use a new sample data.

TODO

• Add support for multiple promotions
• Add CI
• Add support for other currencies
• Add better exception handling on invalid data
