• Transaction Throughput: Simulate high volumes of concurrent transactions to assess system stability and response times.
• Battery Consumption: Monitor application battery usage, especially during background processes like notifications or data synchronization.
• API Response Times: Track response times for all critical API calls to ensure a smooth user experience.

Security Checks Specific to Neobank Apps

• Authentication & Authorization:
• MFA Robustness: Test all MFA methods (SMS, email, authenticator apps, biometrics) for security and reliability.
• Session Management: Verify secure session handling, including timeouts, logout procedures, and prevention of session hijacking.
• Brute-Force Protection: Implement and test measures against brute-force login attempts.
• Data Protection:
• Encryption: Confirm that sensitive data (account numbers, PII, transaction details) is encrypted both in transit (TLS/SSL) and at rest.
• Input Validation: Test for vulnerabilities related to SQL injection, XSS, and other injection attacks on all user input fields.
• Transaction Security:
• Tamper Detection: Verify that transaction details cannot be altered post-submission.
• API Security: Test API endpoints for OWASP Top 10 vulnerabilities, including broken authentication, excessive data exposure, and security misconfigurations.
• Cross-Session Tracking: Ensure that sensitive actions are not vulnerable to cross-session manipulation.
• Device Security: Test for vulnerabilities related to rooted/jailbroken devices and insecure local storage.

Accessibility Checks

• WCAG 2.1 AA Compliance:
• Perceivable: Test for sufficient color contrast, resizable text, and alternative text for non-text content.
• Operable: Verify keyboard navigability, focus management, and sufficient time limits for interactions.
• Understandable: Ensure clear language, predictable navigation, and helpful error identification.
• Robust: Test compatibility with assistive technologies like screen readers (VoiceOver, TalkBack).
• Persona-Based Accessibility:
• Visually Impaired: Simulate usage with screen readers and magnification tools.
• Motor Impaired: Test for alternative input methods and simplified gestures.
• Cognitively Impaired: Evaluate for clear instructions and reduced cognitive load.

Edge Cases Specific to Neobank Apps

• Network Interruption: Test application behavior during intermittent or complete network loss, especially during active transactions.
• Low Battery/Storage: Verify graceful degradation or informative warnings when device resources are critically low.
• Time Zone Changes: Test how the application handles date and time calculations when the device's time zone is altered.
• Concurrent Operations: Simulate users performing multiple actions simultaneously (e.g., checking balance while initiating a transfer).
• Large Data Sets: Test performance and stability when handling extensive transaction histories or numerous linked accounts.
• Internationalization/Localization: Verify currency formatting, date/time formats, and language translations for all supported regions.

Common Bugs in Neobank Apps

• Transaction Duplication: A single transaction appearing multiple times in the history due to race conditions or failed acknowledgments.
