query-orchestration/internal/cognitoauth/cognitotest/auto_refresh_test.go

// Package cognitotest provides end-to-end integration tests for the Cognito authentication system.
//
// This package contains comprehensive tests that validate the complete authentication flow,
// including the critical auto-refresh token functionality. The tests use real browser automation
// via chromedp to simulate actual user interactions and test the full authentication lifecycle.
//
// Key Features Tested:
//   - Full OAuth/PKCE authentication flow with AWS Cognito
//   - Automatic token refresh when tokens expire
//   - Cookie-based token storage and management
//   - Integration with Permit.io for authorization
//   - Real browser interaction using Chrome/Chromium
//   - Natural token expiration testing (5-minute tokens)
//
// Test Requirements:
//   - Valid AWS Cognito configuration
//   - Test user credentials
//   - Chrome/Chromium browser available
//   - ENABLE_REFRESH_TESTS=true environment variable
//
// The tests are designed to catch regressions in the authentication system and ensure
// that users can maintain authenticated sessions without manual re-authentication.

// setupEnvironmentForRefresh ensures all required environment variables are set for refresh testing.
//
// This function validates that all necessary Cognito configuration and test credentials
// are available in the environment. It's a prerequisite step that must pass before any
// authentication testing can begin.
//
// Required Environment Variables:
//   - USER: Test user email/username for Cognito authentication
//   - PASSWORD: Test user password for Cognito authentication  
//   - COGNITO_DOMAIN: AWS Cognito hosted UI domain URL
//   - AWS_REGION: AWS region where Cognito user pool is located
//   - COGNITO_CLIENT_SECRET: OAuth client secret for Cognito app client
//   - COGNITO_USER_POOL_ID: Cognito user pool identifier
//   - COGNITO_CLIENT_ID: Cognito app client identifier
//   - HEADLESS: Optional, controls if browser runs in headless mode (defaults to "true")
//   - DEBUG: Set to "false" for cleaner test output
//
// The function will fail the test immediately if any required variable is missing,
// ensuring tests don't run with incomplete configuration.
//
// Parameters:

// setupTestServerForRefresh creates and configures an Echo server for refresh testing.
//
// This function sets up a complete web server with authentication middleware that
// mimics the production environment. It's essential for testing the auto-refresh
// functionality because it provides the protected endpoints that trigger token
// refresh when accessed with expired tokens.
//
// Server Configuration:
//   - Listens on localhost:8080 (matches Cognito redirect URI configuration)
//   - Uses Echo web framework with logging and recovery middleware
//   - Registers complete Cognito auth middleware stack
//   - Configures Permit.io authorization for protected routes
//   - Sets up structured logging at debug level for detailed test output
//
// Test Endpoints Created:
//   - /home: Public endpoint that shows authentication status and user info
//   - /query: Protected endpoint requiring "exporters", "uploaders", or "querybuilders" role
//   - All Cognito auth routes: /login, /login-callback, /logout
//
// The /query endpoint is crucial for auto-refresh testing because:
//   - It requires valid authentication (triggers token validation)
//   - It's protected by Permit.io authorization (requires valid user context)
//   - It returns a success response when auth succeeds
//   - It's the endpoint we hit to trigger auto-refresh when tokens expire
//
// Parameters:
//   - t: Testing context for logging and test control
//
// Returns:
//   - *http.Server: Configured HTTP server ready to start
//   - *auth.CognitoConfig: Auth configuration used by the server
//
// Usage:
//   - Server must be started in a goroutine: go server.ListenAndServe()
//   - Server should be gracefully shutdown after test: server.Shutdown(ctx)
//   - Config contains auth paths needed for browser navigation

// parseJWTTokenExpiration extracts the expiration time from a JWT token without verification.
//
// This function performs client-side JWT parsing to extract the token's expiration time
// without requiring signature verification or external dependencies. It's specifically
// designed for testing scenarios where we need to know when a token expires so we can
// wait for natural expiration and test auto-refresh functionality.
//
// JWT Structure Parsing:
//   - Expects standard JWT format: header.payload.signature
//   - Extracts and base64-decodes the payload (middle section)
//   - Parses JSON payload to access claims
//   - Specifically looks for the "exp" (expiration) claim
//
// Key Features:
//   - No signature verification (testing purposes only)
//   - Handles base64 URL encoding with proper padding
//   - Converts Unix timestamp to Go time.Time
//   - Robust error handling for malformed tokens
//
// Security Note:
//   This function is for testing only and should never be used in production
//   code where token signature verification is required for security.
//
// Parameters:
//   - tokenString: Raw JWT token string (header.payload.signature format)
//
// Returns:
//   - time.Time: Token expiration time in UTC
//   - error: Error if token is malformed or missing expiration claim
//
// Error Conditions:
//   - Invalid JWT format (not 3 parts separated by dots)
//   - Failed base64 decoding of payload
//   - Invalid JSON in payload
//   - Missing "exp" claim
//   - Invalid expiration value type (not a number)
//
// Usage in Testing:
//   This enables the test to calculate exactly how long to wait for token
//   expiration, allowing for precise timing of auto-refresh scenarios.

// TestAutoRefreshFlow runs the complete end-to-end test for auto refresh functionality.
//
// This is the main integration test that validates the entire auto-refresh token lifecycle
// using real browser automation and natural token expiration. It's designed to catch
// regressions in the authentication system that could break seamless user sessions.
//
// Test Flow Overview:
//   1. Environment Setup: Validates all required configuration
//   2. Server Setup: Creates test server with auth middleware
//   3. Browser Setup: Configures Chrome with appropriate options
//   4. Initial Authentication: Complete OAuth/PKCE login flow
//   5. Token Extraction: Parses JWT to determine expiration time
//   6. Expiration Wait: Waits for natural token expiration (up to 5+ minutes)
//   7. Auto-Refresh Test: Triggers refresh by accessing protected endpoint
//   8. Verification: Confirms new token and continued access
//
// Key Testing Aspects:
//   - Uses real AWS Cognito for authentication (not mocked)
//   - Uses real browser (Chrome/Chromium) for authentic user experience
//   - Tests natural token expiration (5-minute tokens from Cognito)
//   - Validates cookie-based token storage and retrieval
//   - Tests non-rotating refresh token handling
//   - Verifies Permit.io authorization integration
//   - Confirms seamless user experience (no re-authentication required)
//
// Browser Automation Details:
//   - Supports both headless and visible browser modes
//   - Handles Cognito's hosted UI authentication forms
//   - Waits for OAuth redirects and callback handling
//   - Captures and analyzes HTTP cookies for token storage
//   - Tests protected endpoint access before and after refresh
//
// Time Requirements:
//   - Test duration: 5-10 minutes (depends on token expiration time)
//   - Extended timeout: 15 minutes to handle longer token lifecycles
//   - Progress logging: Shows wait progress every 30 seconds
//
// Test Phases (Subtests):
//   1. "Initial Authentication": Complete login flow and cookie capture
//   2. "Extract Token and Log Expiration": JWT parsing and timing calculation
//   3. "Wait for Token Expiration": Patient wait for natural expiration
//   4. "Test Auto Refresh Functionality": Core auto-refresh validation
//   5. "Verify Continued Access After Refresh": Confirms sustained access
//
// Success Criteria:
//   - User successfully authenticates with Cognito
//   - JWT tokens are properly stored in HTTP cookies
//   - Token expiration time is correctly parsed and tracked
//   - Auto-refresh triggers when accessing protected endpoints with expired tokens
//   - New tokens are generated and stored without user intervention
//   - Protected endpoints remain accessible after token refresh
//   - Token expiration times are extended after refresh
//
// Failure Detection:
//   - Missing or invalid authentication tokens
//   - Failed access to protected endpoints
//   - Redirect to login page (indicates failed auto-refresh)
//   - Same token before and after refresh attempt
//   - Earlier expiration time after refresh attempt
//
// Environment Requirements:
//   - ENABLE_REFRESH_TESTS=true (test is skipped otherwise)
//   - Valid Cognito configuration (domain, client ID, secret, etc.)
//   - Test user credentials (USER, PASSWORD environment variables)
//   - Chrome/Chromium browser available on system
//   - Network access to AWS Cognito services
//
// This test is crucial for ensuring users don't experience authentication
// interruptions during long sessions, maintaining a smooth user experience.
