py-cryptocurrency's Introduction

Cryptocurrency

You have some amount of cryptocurrency "Matecoin" in your online wallet. You also bought a program (function get_exchange_rate_prediction) that can predict the exchange rate of your cryptocurrency for the next day.

Write tests for cryptocurrency_action function. This function takes current_rate - current exchange rate of cryptocurrency. This function should return:

  • "Buy more cryptocurrency", if predicted exchange rate is more than 5% higher from the current.
  • "Sell all your cryptocurrency", if predicted exchange rate is more than 5% lower from the current.
  • "Do nothing", if difference is not that much.

Mock get_exchange_rate_prediction function.
