bank_tech_test's Introduction

Bank Tech Test

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

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

Solution

Planning

To plan my solution, I created a Domain Model (initially with classes for Withdrawal and Deposit, but I have since iterated)

Noun	Verb
account	create balance reduce balance increase balance record transactions
statement	print statement
linebuilder	generate lines for statement

Stack

This application was built using the following:

Ruby 2.4.0
Rspec 3.6
Rubocop
Simple Cov

How to Use

Clone this repo

To clone the directory and view the test results:

git clone [email protected]:annalaise/bank_tech_test.git
bundle install
rspec

To see end to end features, within the cloned directory run irb and paste the following:

require './lib/account.rb'
require './lib/statement.rb'
require './lib/linebuilder.rb'
account = Account.new
account.deposit(1000)
account.deposit(2000)
account.withdrawal(500)
linebuilder = LineBuilder.new
statement = Statement.new(account.transactions, linebuilder)
statement.print_statement
