Time

  • 15 minutes - Puesdo-Code and mapping
  • 1 hour - First pass through Vending Machine with core functions - add_coin, enough_change?, check_curr_coin. Spent most of the time with enough_change?. Orginally function was used to calculate the change to be returned to the user.
  • 1.5 hour - refractor core functions and add smaller DRY functions
  • 30 minutes - Dealing with @cash conversion. Eventually went with BigDecimal to remove issues with floats.
  • 45 minutes - Interface.
  • 30 minutes - Cleaning up interface for readability.
