- Requirements
- You should be able to interact with your code via a REPL like IRB or Node.
- Deposits, withdrawal.
- Account statement (date, amount, balance) printing.
- Data can be kept in memory
Given a client makes a deposit of 1000 on 10-01-2023
And a deposit of 2000 on 13-01-2023
And a withdrawal of 500 on 14-01-2023
When she prints her bank statement
Then she would see
date || credit || debit || balance
14/01/2023 || || 500.00 || 2500.00
13/01/2023 || 2000.00 || || 3000.00
10/01/2023 || 1000.00 || || 1000.00
- Clone this repo to your local machine with
git clone https://github.com/JordanManu/bank-tech-test.git - Run
bundle installto install gems - To run the tests using Rspec, you can run the command
rspecin your terminal - To check the quality of the code, use the command
rubocopto run rubocop - To use the program, start by opening irb in your terminal
- To load the program into irb use the command
require "./lib/bank_account.rb" - From there, you can create a new instance of the BankAccount class using
bank = BankAccount.new - To deposit money into the account, use the command bank.deposit(money) eg.
bank.deposit(30) - To withdraw money from the account, use the command bank.withdraw(money) eg.
bank.withdraw(20) - To view a bank statement, use the command
bank.print_statement - Happy depositing!
- My approach to this challenge was to first create the user stories below from the specification given.
- I then used a TDD approach to create simple and effective code.
- I started by having one BankAccount class, then after that was completed and working, I separated it into two classes - BankAccount and Statement.
- The BankAccount class is responsible for handling the transactions, and the Statement class is responsible for printing the Statement.
As a user,
So that I can put money in my account,
I'd like to be able to deposit money in my account
As a user,
So that I can access my money,
I would like to be able to withdraw money from my account
As a user,
So that I know when I accessed my account,
I would like to see the date the transactions took place
As a user,
So that I can see the activity of my account,
I would like to see a transcript of withdrawals with the date and amounts
As a user,
So that I can see my recent account activity first,
I would like to see my transactions in order from most recent to least.
As a user,
So that my account will not go into overdraft,
I would like to not be able to withdraw more money than my account has.
