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

clone this reposition, run bundle install in your terminal and you can interact with the code via IRB. In IRB require './lib/app.rb' type in account = Account.new and then you can make transactions with account.deposit(amount), make a transaction with transaction = Transaction.new(value, type, date ) put it in the log like so log = TransactionLog.new and then log.log_transaction(transaction, account) Make a statement statement = Statement(log) and display it display = Display.new and display.print(statement) If you want to print the transactions just type account.print You'll see all the transactions, last one first.

My approach for this test was TDD. I first wrote a test, tried to pass it and when it passed, I tried to refactor the code written. Then I went on writing another test and so on, until I had all the requirements working. This Red/Green/Refactor cycle helped me get a good structure for this challenge.

I used Ruby for this challenge, Rspec for testing, Simplecov for the testcoverage and Rub0Cop as code analyzer
