Bank tech test

Banking test allows user to interact on a command line

• Open a new bank account
• Deposit and Withdraw fund
• Print or view statement

How to start

• Clone repo to your local machine git clone https://github.com/becc-mu/bank_tech_test
• Run gem install bundle to install dependencies

How to use

• You should be able to use any of your preferred REPL program irb or pry
• Require files
• require './lib/statement'
• require './lib/account'
• Create new account by typing account = Account.new
• Deposit money account.credit(1000)
• Withdraw money account.debit(500)
• To print a statement print account.print_statement

Language and Running tests

• It is written in Ruby and all the tests have passed with Rspec and RuboCop is used for linting.
• Run rspec on command line for tests.

My approach

I started off with two classes Account and Statement.

• Account class is responsible for recording debit and credits
• Statement class is responsible for printing transactions.

After completion of the implementation and the test coverage to 100%, I focused on code quality by extracting responsibility from Account class so each class has no more than one responsibility.

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).

Acceptance criteria

Given a client makes a deposit of 1000 on 10-01-2012 And a deposit of 2000 on 13-01-2012 And a withdrawal of 500 on 14-01-2012 When she prints her bank statement Then she would see
