FizzBuzz – TDD & BDD Example

📘 Overview

This project is a simple student exercise demonstrating the use of TDD (Test-Driven Development)
and BDD (Behavior-Driven Development) through a classic example: FizzBuzz.

The implementation uses:

• Java 21
• Cucumber (BDD)
• JUnit 4
• GitHub Actions CI
• TDD Cycle: Red → Green → Blue

The project starts by defining behavior in Gherkin, generating failing tests (Red), implementing minimal solutions ( Green), and finishing with refactoring (Blue).

🧪 FizzBuzz Rules

• Multiples of 3 → "Fizz"
• Multiples of 5 → "Buzz"
• Multiples of 15 → "FizzBuzz"
• Otherwise, → return the number as a string

All behaviors are fully covered by Gherkin scenarios (fizz_buzz.feature).
