This is a ruby program that can be run in irb or pry, which has the following functionality developed using TDD and using OO principles: (See Specification below for more details).

Enter the following commands in your terminal to download the program:

• git clone https://github.com/shezdev/bank_tech_test.git
• cd into the bank_tech_test directory
• Please run bundle to install the necessary ruby gemfile dependencies

• Type the command pry in your terminal to run the example tests provided in .pryrc
• Alternatively, open irb and enter the following commands:

> bc = BankAccount.new

 => #<BankAccount:0x007fac528b0f78 @balance=0, @log=#<TransactionLog:0x007fac528b0f50 @transactions=[]>>

> bc.deposit("01/01/2012", 100)
 => [{:date=>"01/01/2012", :credit=>100, :debit=>0, :balance=>100}]

> bc.withdraw("02/01/2012", 10)
 => [{:date=>"01/01/2012", :credit=>100, :debit=>0, :balance=>100}, {:date=>"02/01/2012", :credit=>0, :debit=>10, :balance=>90}]

> bc.getStatement
 date      | credit | debit | balance
--------------------------------------
01/01/2012 |   100   |  0  |  100
02/01/2012 |   0   |  10  |  90

NOTE: The following commands will cause the program to exit with the message: "Withdrawal denied: insufficient funds" bc = BankAccount.new bc.withdraw("02/01/2012", 10)

• You should be able to interact with the 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).

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
