Introduction
The testing strategy for BankChase is a multi-layered framework designed to ensure the security, reliability, and performance of a production-ready banking application. It encompasses automated End-to-End (E2E) testing, unit testing, performance benchmarking, and comprehensive security auditing. The strategy prioritizes critical banking flows such as authentication, fund transfers, and data isolation.
The framework utilizes Playwright for E2E workflows and browser automation, Jest for unit testing of components and utilities, and a structured CI/CD pipeline via GitHub Actions to maintain code quality throughout the development lifecycle. This ensures that features like Role-Based Access Control (RBAC) and durable transaction workflows are verified before deployment.

Testing Architecture
The BankChase testing ecosystem is divided into three primary layers, ensuring coverage from individual code units to full user journeys.
Multi-Layer Testing Model
The testing layer hierarchy ensures that basic code quality is verified before expensive E2E and API tests are executed.

Framework Components
| Framework | Scope | Key Features |
|---|---|---|
| Playwright | E2E & UI | Multi-browser support (Chromium, Firefox, WebKit), Mobile emulation, Visual regression. |
| Jest | Unit & Integration | Coverage reporting, watch mode, component isolation. |
| GitHub Actions | Automation | Triggers on push/PR, artifact generation, automated build verification. |

End-to-End (E2E) Testing
E2E testing is powered by Playwright and focuses on validating real-world user scenarios across multiple platforms and viewports.
DNS and Infrastructure UI
Automated tests verify complex administrative interfaces, specifically DNS management. These tests cover CRUD operations, validation handling, and responsive design.
- Operations Tested: Creation of A, CNAME, MX, and TXT records; record updates and deletions.
- UI Verification: Table filtering, sorting, copy-to-clipboard, and pagination.
- Accessibility: Heading hierarchy, button labels, and keyboard navigation support.

Cloudflare & R2 API Integration
The system includes dedicated tests for external service integrations, ensuring the banking platform interacts correctly with cloud infrastructure.
- DNS API: Listing zones and record creation validation.
- R2 Storage: Object listing, file uploads, and presigned URL generation.
- Error States: Rate limiting (429), missing authentication, and malformed JSON handling.

Security and Compliance Auditing
Given the banking context, the QA process includes a rigorous security checklist to verify data isolation and protection.
RBAC and Authorization Verification
The testing suite ensures that Role-Based Access Control is strictly enforced at both the API and UI levels.
Logic flow for Role-Based Access Control verification during security testing.

Core Security Requirements
- Authentication: Verification of 2FA codes (5-minute expiration), JWT signing, and session revocation.
- Data Protection: Parameterized queries to prevent SQL injection, XSS blocking, and sanitization of sensitive data in logs.
- PIN Management: Bcrypt hashing for PINs, lockout mechanisms after 3 failed attempts (15-minute duration), and format validation.

Testing Checklists and Scenarios
The project utilizes structured checklists to ensure manual and automated verification covers all edge cases before deployment.
Functional Testing Scenarios
| Scenario | Category | Expected Outcome |
|---|---|---|
| Rate Limiting | Performance | /api/transfers/send limited to 10/min; returns 429 status. |
| Drift Analysis | Behavioral | High drift score triggers biometric review or additional validation. |
| Receipt Generation | Transactions | Unique receipt number generated with correct balances and currency. |
| Zero-Balance | Data Integrity | New accounts must start with exactly $0.00 balance. |

Browser and Device Support
QA includes verification across the following targets:
- Browsers: Chrome, Firefox, Safari, Edge (Latest versions).
- Mobile: Pixel 5 emulation, Mobile Safari (iOS), Chrome Mobile (Android).
- Viewports: Mobile (375x667), Tablet (768x1024), and Desktop.
