mvn spring-boot:run

Features

• Create account
• Add credit to account
• Debit account
• Get Account details and Balance
• Get all Accounts and Balances
• Transaction history for all Accounts, including unsuccessful transactions
• Unit tests to cover core features

Constraints

• All transactions, both credit and debit, must have unique id's. If not, an exception is thrown
• A debit transaction will be deemed unsuccessful if the debited amount is greater that the current balance

Notes

• Due to the scope of the assignment, I have decided to use a simple JSON file to act as the database for the application.
• The JSON file containing the accounts can be found at: src/main/resources/accounts.json
• Please do not manually change values stored in the accounts.json file. Values should only be updated through API calls/requests
• The application will run on port 8080
