Test Framework Layers

• Test Layer: Contains test scripts that simulate attacks and check authentication flows (e.g., brute force, session fixation).
• Page Object Layer: Encapsulates UI elements and actions for login, password reset, and MFA pages to keep tests clean.
• Utility Layer: Provides helper functions for HTTP requests, token handling, and generating test data like invalid passwords.
• Configuration Layer: Holds environment settings, credentials, and security parameters to run tests against different setups.
• Reporting Layer: Collects test results and generates readable reports for quick vulnerability assessment.

Configuration Patterns

• Environment Config: Use config.yaml to define URLs, API endpoints, and environment types (dev, staging, prod).
• Credentials Management: Store sensitive data like usernames and passwords securely in secrets.yaml and load them at runtime.
• Browser and API Settings: Define browser types or API headers in config to switch easily between test targets.
• Parameterization: Use fixtures or config files to run tests with different user roles and attack vectors without code changes.

Test Reporting and CI/CD Integration

• Generate HTML or XML reports after test runs to summarize passed and failed authentication vulnerability tests.
• Integrate with CI/CD pipelines (e.g., Jenkins, GitHub Actions) to run tests automatically on code changes or deployments.
• Use alerts or dashboards to notify security teams immediately if critical authentication vulnerabilities are detected.
• Keep historical reports in the reports/ folder for audit and trend analysis.

Framework Design Principles

1. Separation of Concerns: Keep test logic, page interactions, and utilities separate for easy maintenance.
2. Data-Driven Testing: Use external data files or fixtures to test multiple authentication scenarios and attack types.
3. Explicit Waits and Validation: Wait for UI elements or API responses to ensure tests check real application behavior.
4. Secure Handling of Credentials: Never hardcode sensitive data; use secure config and environment variables.
5. Reusable Components: Build common functions for repeated actions like login attempts or token validation to reduce duplication.

Self Check

Where in this folder structure would you add a new test script to verify if the application properly locks an account after multiple failed login attempts?

Key Result

Organize authentication vulnerability tests with clear layers for tests, page objects, utilities, config, and reporting to ensure maintainability and security.
