Bank account app written in Ruby and interacted with through CLI

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).

My approach

• I began by reading through the requirements and decomposed them into user stories in order to better determine the objects and functionality required

User stories

• As a user of the bank the new account I should be able to see the balance is 0
• As a user of the bank I want to deposit my money in the bank and receive a confirmation and my current balance
• As a user of the bank I want to query my balance any time while using the app
• As a user of the bank I want to withdraw a given amount of money and receive a confirmation and my current balance
• As a user of the bank, to see my recent activity, I would like to see a print out of my statement showing my activity in reverse chronological order

How to use

• Use Ruby version 2.5.0
• Clone this repo
• Change directory into 'bank_test_ruby'
• Run 'bundle install'
• Run specs through 'rspec'
• run ruby app.rb in CLI

Improvements

• Refactor into classes
• Check tests are not tightly coupled to code
