better-bank-tech-test

I'm challenging myself to re-do an tech test tech that was completed with makers.

##Requirements

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 Must have features for deposits and withdrawal Must have a feature to display account statement (date, amount, balance) Data can be kept in memory (it doesn't need to be stored to a database or anything)

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:

Planning

I previous compelted this task on makers here, but I wanted to attempt the challenge again and go further than the mvp that was provided by adding my own extra functionalities that would make sense in comparision to a bank account/atm.

I started by doing a simple diagram of how I waned to spilt the functionality between two classes and what addtional functionalities I wanted within in the project.

I've also focused on commiting before every failed test and passed test with commits to keep it consistent with addtional commits if there was a bug or a change needed.

How to use

Installing and testing

In the terminal of the folder input:

1. nvm install node
2. nvm use node
3. npm install jest
4. jest - this step is optional if you want to run the test.

Running the application

You need to be in the directory of the files for this to work

1. node
2. const BankAccount = require('./BankAccount')
3. const Statement = require('./Statement')
4. const account = new BankAccount

Bank Account functionality (optional)

All bank account start at a nil balance, so withdrawing when having a nil balance will throw an error

5. To make a deposit you use account.deposit(500) which would put 500 in the account.
6. To make a withdrawal you use account.withdraw(500) which takes 500 out of the account.
7. Check the balance of the account by account.getBalance();
8. You can alter the amount of the balance without the functions like this: account.balance = 500, which would make it 500 instead of the starting amount of 0

Statement Account functionality (optional)

9. const statement = new Statement(account) this puts the bank account in to the statment generator

10. statement.printStatement();

An example of this is below.
