Product Price Updater

A utility that fetches product data from an API and applies pricing transformations during the JSON parsing process.

Capabilities

Price Markup Application

Apply a percentage-based markup to product prices as the JSON data streams in.

  • Given a product with price 100 and markup 10%, the transformed price is 110 @test
  • Given a product with price 50 and markup 20%, the transformed price is 60 @test
  • Given multiple products with prices [100, 200, 50] and markup 15%, the transformed prices are [115, 230, 57.5] @test

Currency Conversion

Convert prices from one currency to another during JSON parsing.

  • Given a product price of 100 USD with conversion rate 1.2 to EUR, the converted price is 120 @test
  • Given multiple products with USD prices and a conversion rate of 0.85 to GBP, all prices are converted correctly @test
