Bank Kata (Technical Test for Skypay)

This project is my solution for the Bank Kata technical test as part of my application for the QA and Test Automation Engineer position at Skypay. The goal was to implement a simple bank account system while applying Mockist principles and acceptance testing with Cucumber.

Objectives and Constraints

This implementation adheres to the following requirements:

🔹 Implement a class Account that conforms to the given interface

🔹 Use Mockist approach to drive the architecture and validate interactions with dependencies.

🔹 Simulate bank statement printing via a mocked StatementPrinter class.

🔹 Write JUnit and Cucumber tests to validate functionality and ensure non-regression.

Technologies Used

• Java 17
• Spring Boot for application framework
• Maven for dependency management
• JUnit 5 for unit testing
• Mockito for mocking dependencies
• Cucumber for BDD-style acceptance testing
• IntelliJ IDEA for development and test execution
