Banking Kata Java

Java kata for practicing banking-domain behavior with BDD/TDD style tests.

Purpose

This repository is a learning kata. It is useful for practicing domain modeling, test-driven development, and behavior-driven scenarios in a small banking context.

Example Scenarios

• Deposit money and print the account statement.
• Deposit, withdraw, and verify the final balance.
• Withdraw into a negative balance and verify the behavior.

How To Use

Run the test suite from the IDE or command line.

mvn test

Status

Learning kata. The next upgrade is to clarify the domain rules, add example outputs, and modernize dependencies if this repo becomes active again.

Validation

The core validation path is the behavior test suite. Add scenarios whenever a new business rule is introduced.

Engineering Notes

The important engineering signal is not the framework choice; it is whether the domain language, examples, and tests make the banking rules unambiguous.
