Story 12: Testing & Security Validation

[sapientpants]

Overview

Implement comprehensive testing suite and conduct security validation to ensure the implementation meets enterprise requirements.

Acceptance Criteria

• Unit tests for all OAuth components
• Integration tests for auth flows
• End-to-end tests with real IdPs
• Load testing (1000+ concurrent users)
• Security testing (OWASP Top 10)
• Penetration testing
• MCP compliance testing
• Performance benchmarks
• Chaos engineering tests
• Multi-tenant isolation tests

Test Scenarios

• Token validation edge cases
• Permission filtering accuracy
• Service account failover
• High concurrency handling
• Token expiration during long operations
• Network failures and retries
• Malicious input handling
• Cross-tenant data leakage prevention

Security Validation

• No token passthrough verification
• Audience validation testing
• PKCE flow validation
• Session fixation prevention
• CSRF protection validation

Performance Requirements

• <100ms token validation
• <500ms average request latency
• Support 1000+ concurrent users
• 99.9% uptime

Dependencies

• All implementation stories
