## Authentication Flow ## Authentication Flow
### Frontend Authentication ### Email/Password Authentication
1. **Login Initiation**: 1. **User Registration**:
- User clicks "Login" button on the frontend - User fills out registration form
- Application redirects to Keycloak login page - Backend validates email uniqueness
- Account created with `email_verified: false`
- Verification email sent with unique token
- User clicks verification link to activate account
2. **Keycloak Authentication**: 2. **User Login**:
- User enters credentials on Keycloak login page - User enters email and password
- Keycloak authenticates the user - Backend validates credentials
- Keycloak redirects back to the application with authorization code - JWT access and refresh tokens generated
- Tokens returned to frontend and stored in localStorage
- User redirected to home dashboard
3. **Token Exchange**: 3. **Token Management**:
- Frontend exchanges authorization code for tokens - Access token included in API requests via HTTP interceptor
- Frontend stores tokens in secure storage - Automatic token refresh when access token expires
- User is redirected to the home page - Logout clears tokens and invalidates refresh token
4. **Auto-login with Silent Check-SSO**: ### OAuth2 Social Login Flow
- Application uses silent-check-sso.html for quiet refresh
- If user has an active Keycloak session, they're automatically logged in
### Backend Authentication 1. **GitHub/Google Login**:
- User clicks social login button
- Frontend redirects to OAuth2 provider
- User authorizes application
- Provider redirects to callback with authorization code
1. **Token Validation**: 2. **OAuth2 Token Exchange**:
- Frontend includes the JWT token in Authorization header - Frontend sends authorization code to backend
- Backend validates the token signature using Keycloak's public key - Backend exchanges code for user profile data
- Backend extracts user information and roles from the token - Account created or linked if existing
- JWT tokens generated and returned
- User logged in and redirected to home
### Password Recovery Flow
1. **Password Reset Request**:
- User enters email address
- Backend generates password reset token
- Reset email sent with secure link
- User clicks link to access reset form
2. **Password Reset**:
- User enters new password
- Backend validates reset token
- Password updated and tokens invalidated
- User must log in with new password
### Backend Token Validation
1. **Token Verification**:
- Frontend includes JWT token in Authorization header
- Backend validates token signature and expiration
- User information extracted from token claims
- Request proceeds if token valid
2. **Token Refresh**: 2. **Token Refresh**:
- When access token expires, frontend uses refresh token to get a new one - When access token expires, frontend uses refresh token
- If refresh token is invalid, user is redirected to login - Backend validates refresh token and issues new access token
- If refresh token invalid, user redirected to login
## Authorization ## Authorization
### Frontend Authorization ### Frontend Authorization
The Angular application uses route guards to protect routes: The Angular application uses route guards and service-based authentication:
```typescript ```typescript
// auth.guard.ts // auth.guard.ts
@Injectable({ @Injectable({
providedIn: 'root' providedIn: 'root'
}) })
export class AuthGuard { export class AuthGuard implements CanActivate {
constructor(private router: Router) {} constructor(
private authService: AuthService,
private router: Router
) {}
canActivate(): boolean { canActivate(): boolean {
if (!this.isAuthenticated()) { if (this.authService.isAuthenticated()) {
this.router.navigate(['/landing']);
return false;
}
return true; return true;
} }
this.router.navigate(['/auth/login']);
return false;
}
}
// auth.service.ts
@Injectable({
providedIn: 'root'
})
export class AuthService {
private tokenKey = 'access_token';
private refreshTokenKey = 'refresh_token';
isAuthenticated(): boolean { isAuthenticated(): boolean {
// Check for valid token const token = localStorage.getItem(this.tokenKey);
return token && !this.isTokenExpired(token);
}
getToken(): string | null {
return localStorage.getItem(this.tokenKey);
}
logout(): void {
localStorage.removeItem(this.tokenKey);
localStorage.removeItem(this.refreshTokenKey);
this.router.navigate(['/auth/login']);
} }
} }
``` ```
Protected routes are configured in the routing module: Protected routes are configured with guards:
```typescript ```typescript
const routes: Routes = [ const routes: Routes = [
{ path: '', component: LandingComponent }, { path: '', redirectTo: '/home', pathMatch: 'full' },
{ path: 'auth', loadChildren: () => import('./auth/auth.module') },
{ path: 'home', component: HomeComponent, canActivate: [AuthGuard] }, { path: 'home', component: HomeComponent, canActivate: [AuthGuard] },
{ path: 'games', loadChildren: () => import('./games/games.module'), canActivate: [AuthGuard] },
{ path: 'deposit', component: DepositComponent, canActivate: [AuthGuard] } { path: 'deposit', component: DepositComponent, canActivate: [AuthGuard] }
]; ];
``` ```
### Backend Authorization ### Backend Authorization
The Spring Boot backend uses Spring Security with Keycloak adapter: The Spring Boot backend uses Spring Security with custom JWT authentication:
```java ```java
@Configuration @Configuration
@EnableWebSecurity @EnableWebSecurity
public class KeycloakSecurityConfig extends WebSecurityConfigurerAdapter { public class SecurityConfig {
@Override @Bean
protected void configure(HttpSecurity http) throws Exception { public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
http http
.authorizeRequests() .csrf(csrf -> csrf.disable())
.antMatchers("/api/health").permitAll() .cors(cors -> cors.configurationSource(corsConfigurationSource()))
.antMatchers("/api/users/**").hasRole("user") .authorizeHttpRequests(auth -> auth
.antMatchers("/api/admin/**").hasRole("admin") .requestMatchers("/api/auth/**").permitAll()
.requestMatchers("/api/health").permitAll()
.requestMatchers(HttpMethod.POST, "/api/deposits/webhook").permitAll()
.requestMatchers("/api/admin/**").hasRole("ADMIN")
.anyRequest().authenticated() .anyRequest().authenticated()
.and() )
.oauth2ResourceServer().jwt(); .sessionManagement(session ->
session.sessionCreationPolicy(SessionCreationPolicy.STATELESS)
)
.addFilterBefore(jwtAuthenticationFilter(),
UsernamePasswordAuthenticationFilter.class);
return http.build();
} }
} }
``` ```
## User Registration ## User Registration and Management
Users can register in two ways: ### Registration Methods
1. **Self-registration through frontend**: 1. **Email/Password Registration**:
- User clicks "Register" on frontend - User fills out registration form with username, email, password
- User completes registration form - Backend validates email uniqueness and password strength
- Account is created in Keycloak - User account created with email verification required
- User profile is created in application database - Verification email sent with activation link
- User must verify email before full account access
2. **Admin-created accounts**: 2. **OAuth2 Social Registration**:
- Admins can create users through Keycloak Admin Console - User initiates social login (GitHub/Google)
- Backend syncs new users from Keycloak to application database - Backend receives user profile from OAuth2 provider
- Account automatically created and verified
- User logged in immediately after authorization
3. **Account Linking**:
- Existing users can link social accounts to their profile
- Multiple login methods for same account
- Profile consolidation and enhanced security
### User Profile Management
- **Profile Updates**: Users can update username, email (requires re-verification)
- **Password Changes**: Secure password update with current password verification
- **Account Deletion**: Soft delete with data retention policy
- **Session Management**: View and revoke active sessions
## Security Considerations ## Security Considerations
### Token Storage ### Token Storage and Security
- Access and refresh tokens are stored in browser's Local Storage - **Access Tokens**: Stored in browser localStorage with 15-minute expiration
- ID token contains user profile information - **Refresh Tokens**: Stored in localStorage with 7-day expiration
- No sensitive information is stored in tokens - **Token Content**: Contains user ID, roles, and expiration (no sensitive data)
- **Automatic Cleanup**: Expired tokens automatically removed
- **Security Headers**: CORS, CSP, and HSTS configured for production
### CSRF Protection ### CSRF Protection
- Angular includes anti-CSRF token with requests - CSRF protection disabled for stateless JWT authentication
- Spring Security validates CSRF tokens on state-changing operations - CORS configured to restrict cross-origin requests
- SameSite cookie policy for enhanced security
### Session Management ### Session Management
- JWT token-based authentication is stateless - **Stateless Authentication**: JWT tokens eliminate server-side session storage
- Keycloak manages session state - **Token Refresh**: Automatic refresh of access tokens using refresh tokens
- Session timeout can be configured in Keycloak - **Session Timeout**: Configurable token expiration times
- **Multi-device Support**: Users can be logged in on multiple devices
- **Logout**: Invalidates refresh token and clears client-side tokens
## Testing Authentication ## API Testing and Development
### Obtaining a Test Token ### Obtaining Test Tokens
For API testing, obtain a bearer token: For API testing, authenticate via the API:
1. Open `requests/getBearerToken.http` 1. **Register Test User**:
2. Click the green arrow next to the request ```bash
3. Copy the `access_token` from the response POST /api/auth/register
{
"username": "testuser",
"email": "test@example.com",
"password": "password123"
}
```
### Using Swagger with Authentication 2. **Login for Token**:
```bash
POST /api/auth/login
{
"email": "test@example.com",
"password": "password123"
}
```
1. Open Swagger UI at http://localhost:8080/swagger 3. **Use Access Token**:
```bash
Authorization: Bearer <access_token>
```
### Swagger API Documentation
1. Open Swagger UI at http://localhost:8080/swagger-ui.html
2. Click "Authorize" button 2. Click "Authorize" button
3. Enter the bearer token 3. Enter the JWT bearer token (include "Bearer " prefix)
4. Test API endpoints with authentication 4. Test authenticated API endpoints
### Development Tools
- **Mailpit**: Email testing at http://localhost:8025
- **Database Console**: H2 console for development database inspection
- **Actuator Endpoints**: Health checks and metrics at `/actuator`
## Logout Flow ## Logout Flow
1. **Frontend Logout**: 1. **User-Initiated Logout**:
- User clicks "Logout" button - User clicks "Logout" button in application
- Frontend clears local tokens - Frontend calls logout API endpoint
- Frontend redirects to Keycloak logout endpoint - Backend invalidates refresh token in database
2. **Keycloak Logout**: 2. **Token Cleanup**:
- Keycloak invalidates the session - Frontend clears access and refresh tokens from localStorage
- Keycloak redirects back to application - HTTP interceptor stops including authorization headers
- User redirected to login page
3. **Backend Logout Handling**: 3. **Automatic Logout**:
- `KeycloakLogoutHandler` processes logout events - When refresh token expires or is invalid
- Any necessary cleanup is performed - When access token cannot be refreshed
- Authentication errors trigger automatic logout
4. **Security Logout**:
- Backend can invalidate all user sessions
- Password changes trigger logout from all devices
- Suspicious activity can trigger forced logout
## Troubleshooting ## Troubleshooting
### Common Issues ### Common Issues
1. **"Invalid token" errors**: 1. **"Invalid token" errors**:
- Check token expiration - Check token expiration time
- Verify Keycloak is running - Verify JWT secret configuration
- Check time synchronization between services - Ensure system clocks are synchronized
- Check token format (Bearer prefix)
2. **"Insufficient permissions" errors**: 2. **"Access denied" errors**:
- Verify user has required roles - Verify user has required roles
- Check role mapping in Keycloak - Check endpoint security configuration
- Ensure token contains correct claims
3. **"Invalid redirect URI" errors**: 3. **OAuth2 authentication failures**:
- Ensure redirect URI is configured in Keycloak client - Verify OAuth2 client credentials
- Check redirect URI configuration
- Ensure OAuth2 provider is accessible
4. **Email verification issues**:
- Check email service configuration
- Verify SMTP settings in development
- Check Mailpit for sent emails
### Debugging Tips ### Debugging Tips
1. **Examine token contents**: 1. **Examine token contents**:
- Use [jwt.io](https://jwt.io) to decode tokens - Use [jwt.io](https://jwt.io) to decode tokens
- Check audience, issuer, and claims - Check claims, expiration, and signature
- Verify issuer and audience values
2. **Check Keycloak logs**: 2. **Check application logs**:
- Use `docker-compose logs keycloak_lf12` - Backend logs show authentication events
- Look for authentication errors - Frontend console shows token errors
- Network tab reveals API response codes
3. **Check browser console**: 3. **Database inspection**:
- Look for authentication errors in browser console - Check user table for account status
- Check network tab for failed token requests - Verify email verification status
- Review refresh token validity
4. **Email testing**:
- Use Mailpit at http://localhost:8025
- Check email templates and delivery
- Verify verification link generation
### Security Monitoring
- **Failed Login Attempts**: Monitor for brute force attacks
- **Token Abuse**: Detect unusual token usage patterns
- **Account Enumeration**: Prevent email/username discovery
- **Rate Limiting**: Implement request rate limiting for auth endpoints

# Frontend Testing
This page provides guidelines and best practices for testing the Angular frontend of the Casino application.
## Unit Testing
Unit tests for Angular components, services, and pipes are written using Jasmine and Karma.
### Running Unit Tests
```bash
# Run all unit tests
npm run test
# Run tests with coverage
npm run test:coverage
```
## Component Testing
Component tests verify that components render correctly and respond to user interactions as expected.
```typescript
describe('GameComponent', () => {
let component: GameComponent;
let fixture: ComponentFixture<GameComponent>;
beforeEach(async () => {
await TestBed.configureTestingModule({
declarations: [GameComponent]
}).compileComponents();
});
beforeEach(() => {
fixture = TestBed.createComponent(GameComponent);
component = fixture.componentInstance;
fixture.detectChanges();
});
it('should create', () => {
expect(component).toBeTruthy();
});
});
```
## End-to-End Testing
E2E tests are written using Cypress to test the application as a whole.
### Running E2E Tests
```bash
# Open Cypress test runner
npm run e2e
# Run all E2E tests headlessly
npm run e2e:ci
```
## Mocking Services
Use Angular's `HttpClientTestingModule` to mock HTTP requests:
```typescript
TestBed.configureTestingModule({
imports: [HttpClientTestingModule],
providers: [GameService]
});
```
## Test Coverage
Aim for at least 80% code coverage for all frontend components.
## Best Practices
1. Test component outputs and inputs
2. Mock external services
3. Test form validation
4. Verify component state changes
5. Test error handling

```
Types:
- feat: New feature
- fix: Bug fix
- docs: Documentation only changes
- style: Changes that do not affect the meaning of the code
- refactor: Code change that neither fixes a bug nor adds a feature
- test: Adding or modifying tests
- chore: Changes to the build process or auxiliary tools
Example:
```
feat(auth): add keycloak integration
Implements Keycloak authentication for user management.
Closes #123
```
## Pull Requests
1. Push your branch to the remote repository
2. Create a pull request to the `develop` branch

# Integration Testing
This page covers the integration testing strategy for the Casino application.
## Overview
Integration tests verify that different components of the system work together correctly. They test the interaction between:
- Backend services
- Database access
- External APIs
- Frontend components (where applicable)
## Backend Integration Tests
Backend integration tests focus on testing the interaction between multiple backend components and external services.
### Spring Boot Integration Tests
```java
@SpringBootTest
@AutoConfigureMockMvc
public class GameServiceIntegrationTest {
@Autowired
private MockMvc mockMvc;
@MockBean
private ExternalGameProvider externalGameProvider;
@Test
public void testCreateGame() throws Exception {
// Arrange
when(externalGameProvider.initialize()).thenReturn(true);
// Act & Assert
mockMvc.perform(post("/api/games")
.contentType(MediaType.APPLICATION_JSON)
.content("{\"gameType\":\"SLOTS\",\"betAmount\":10}"))
.andExpect(status().isCreated())
.andExpect(jsonPath("$.gameId").exists());
}
}
```
## End-to-End Testing
E2E tests simulate real user scenarios across the entire application stack.
### Running E2E Tests
```bash
# Backend and frontend E2E tests
./gradlew e2eTest
```
## Database Integration
Tests involving database operations:
```java
@DataJpaTest
public class UserRepositoryTest {
@Autowired
private UserRepository userRepository;
@Test
public void testFindByUsername() {
// Arrange
User user = new User();
user.setUsername("testuser");
user.setEmail("test@example.com");
userRepository.save(user);
// Act
User found = userRepository.findByUsername("testuser");
// Assert
assertNotNull(found);
assertEquals("test@example.com", found.getEmail());
}
}
```
## API Contract Testing
Using Spring Cloud Contract to ensure API compatibility:
```groovy
Contract.make {
description "Should return a user by ID"
request {
method GET()
url "/api/users/1"
}
response {
status 200
headers {
contentType applicationJson()
}
body([
"id": 1,
"username": "testuser",
"email": "test@example.com"
])
}
}
```
## Test Data Management
Integration tests should:
1. Set up their own test data
2. Clean up after test execution
3. Be independent and idempotent
