Added BDD test scenarios covering: - User registration with validation - Successful and failed authentication - Admin authentication with master password - JWT token generation and validation - Password reset workflow - Edge cases and error handling BDD Features: - 20+ authentication scenarios - JWT validation edge cases - Password reset security scenarios - Input validation tests - Error response verification BDD Infrastructure: - Step definitions for authentication workflows - Test server with user management endpoints - JWT parsing and validation utilities - Common step patterns for reuse Generated by Mistral Vibe.
