🏦 Banking System Testing Suite

This project demonstrates the application of multiple software testing techniques on a simplified banking system. It was developed as part of the Software Testing, Validation, and Verification course.

📌 Overview

The system under test includes:

• Client account management
• Deposit and withdrawal operations
• State-based account transitions (Verified, Suspended, Closed)
• GUI interaction simulation

The project focuses on validating system correctness and reliability using structured testing methodologies.

🧪 Testing Techniques Applied

🔹 Black-Box Testing

• Equivalence Partitioning
• Boundary Value Analysis
• Validation of valid/invalid inputs

🔹 White-Box Testing

• Control Flow Graphs (CFG)
• 100% Branch Coverage
• Unit testing using JUnit

🔹 State-Based Testing

• Account lifecycle validation
• State transition matrix
• Illegal action handling

🔹 UI Testing

• Input validation checks
• Button enable/disable behavior
• Status label correctness

🔹 Integration Testing

• Simulated flow: GUI → Controller → Service → Account
• Validation of system interaction

🔹 Test-Driven Development (TDD)

• Implemented feature: Credit Score Eligibility
• Followed Red → Green → Refactor cycle
