Bank tech_test

IRB app which displays account total, allows to withdraw and deposit money, displays statement.

My approach

My approach to this challenge was to first understand the requirements, which made me chose Ruby as a language since I am the most familiar with it. Next I wrote user stories, so I could direct the development and develop the features. I used TDD to avoid errors and move in small steps. I have separated the logic into multiple classes to follow SOLID principles as best as I could. Have I had more time I would implement future updates, see below.

Set Up

• Clone the repo [email protected]:Edy1988/bank_test.git
• Run the command bundle to install dependencies

MVP User Stories

As a user,
So I can manage my money
I have an account.

As a user,
So I can use my account,
I can deposit money.

As a user,
So I can use my account,
I can withdraw money.

As a user,
So I can keep track of my funds,
I can view statement in this format:
date || credit || debit || balance
14/01/2012 || || 500.00 || 2500.00
13/01/2012 || 2000.00 || || 3000.00
10/01/2012 || 1000.00 || || 1000.00

To set up the project

Clone the repo [email protected]:Edy1988/bank_test.git and then run:

$ bundle

To run the app in IRB:

• Open irb and run require './lib/account.rb'
• Follow the instructions below:

account = Account.new
=> creates a new bank account instance

account.deposit(100)
 => adds funds to account

account.withdraw(10)
 => deducts funds from account

account.print_statement
=> Date || Credit || Debit || Balance
05/12/2018 || 0 || 10 || 90
05/12/2018 || 100 || 0 || 100

To run tests:

rspec

To run linting:

rubocop

Future updates

1. Add confirmation when transaction was made.
2. Fixed 'line too long' linter errors.
