10/01/2012 || 1000.00 || || 1000.00

My Domain Model

Technologies

• Ruby
• Rspec
• Rubocop

Set up Appplication

In terminal / command line enter following commands

git clone https://github.com/KKOA/bank-tech-test
cd bank-tech-test
bundle install

Run in the terminal/command prompt:

 cd bank-tech-test
 irb

Create a bank account by creating an instance of the bank account constructor object.
The constructor takes two optional arguments.

• start balance
• date account created

  account = Account.new([start_balance,date]);

  If no arguments are submitted then account is created balance of 0 and date created as today date in day/month/year format.

Account Class has 3 methods

• deposit
• withdraw
• current_balance

Both deposit and withdraw take mandatory amount argument and optional date of transcation.
Date of transcation by default is current date.
Current does not require any argument and returns the current balance

account.deposit(amount[,date])
account.withdraw(amount[,date])
account.current_balance()

To print account statement you must creating an instance of the printer constructor object and pass an account as argument. You can then call print on the object to output the account statement.

printer = Printer.new(account.logs)
puts printer.print()
