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
