TDD Approach for bank

Primary LanguageRuby

Bank tech test

Today, you'll practice doing a tech test.

For most tech tests, you'll essentially have unlimited time. This practice session is about producing the best code you can when there is a minimal time pressure.

You'll get to practice your OO design and TDD skills.

You'll work alone, and you'll also review your own code so you can practice reflecting on and improving your own work.

Specification

Requirements

  • You should be able to interact with your code via a REPL like IRB or the JavaScript console. (You don't need to implement a command line interface that takes input from STDIN.)
  • Deposits, withdrawal.
  • Account statement (date, amount, balance) printing.
  • Data can be kept in memory (it doesn't need to be stored to a database or anything).
