Today, you'll practice doing a tech test.
For most tech tests, you'll essentially have unlimited time. This practice session is about producing the best code you can when there is a minimal time pressure.
You'll get to practice your OO design and TDD skills.
You'll work alone, and you'll also review your own code so you can practice reflecting on and improving your own work.
- You should be able to interact with your code via a REPL like IRB or Node. (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 10-01-2023 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
Once you have completed the challenge and feel happy with your solution, here's a form to help you reflect on the quality of your code: https://docs.google.com/forms/d/1Q-NnqVObbGLDHxlvbUfeAC7yBCf3eCjTmz6GOqC9Aeo/edit
One-line command for the terminal that sets up RSpec and inits a git repo for project.
bundle init; bundle add rspec; rspec --init; mkdir lib; git init; git add .; git commit -m "setup"
As a user, so I can manage my money,
I'd like a bank account that keeps track of my balance.
As a user, so I can store my money,
I'd like to be able to deposit money into my bank account.
As a user, so I can spend my money,
I'd like to be able to withdraw my money.
As a user, so I can see a summary of all my transactions,
I'd like to be able to print a bank statement.
As a user, so I can get an overview of my spending,
I'd like to see the date, amounts in/out and my balance for each transaction on my bank statement.
Initial approach split different classes to eliminate each class function then combine to get to result.
- BankAccount- main
- Activity- deposit, withdraw
- Transaction-process tree
- Statement - sum of transactions
I have difficulty at the beginning to print out process after testing pass
- Clone this repo to your local machine using
git@github.com:RedPRO16/bank_tech_Ruby.git - Install dependencies:
$ bundle install
$ cd bank_tech_Ruby
Then open within irb:
$ irb -r './lib/bank_acc.rb'
Create a new bank account:
> acc = BankAcc.new
To make a deposit of 1000:
> acc.deposit(1000)
To make a deposit of 2000:
> acc.deposit(2000)
To make a withdrawal of 500:
> acc.withdraw(500)
To print statement:
> acc.print
This will produce the following output in line with acceptance criteria:
