Cash rules everything around me

The Bank Tech Test

Check the commit log for this, I've heavily annotated each commit to explain what I've been doing as I've cleaned up the code.

Resources

This solution was influenced by those done by Sandro Mancuso in Java:

• Bank Kata walkthrough - part 1
• Bank Kata walkthrough - part 2
• Bank Kata walkthrough - part 3
• Code for a slightly different version by Sandro

When in doubt, go for the simplest solution

Requirements

• Deposits, withdrawal
• Account statement (date, amount, balance)
• Statement printing

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

• Graphical interface
