A tech test to practice code quality.

Specification · Installation · Running locally · Testing · Process · Feedback

Specification

• 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).

Acceptance criteria

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
