+# Security Module Tests
+
+This directory contains comprehensive unit tests for the security module of the LearnHouse API.
+
+## Test Structure
+
+The security tests are organized into the following files:
+
+### Core Security Tests
+- **`test_security.py`** - Tests for password hashing, JWT constants, and core security functions
+- **`test_auth.py`** - Tests for JWT authentication, user authentication, and token management
+
+### Role-Based Access Control (RBAC) Tests
+- **`test_rbac.py`** - Tests for RBAC authorization functions and user permissions
+- **`test_rbac_utils.py`** - Tests for RBAC utility functions like element type checking
+
+### Feature Usage Tests
+- **`test_features_utils.py`** - Tests for feature usage tracking and limits
+
+### Comprehensive Tests
+- **`test_security_all.py`** - Comprehensive test suite that imports and validates all security modules
+
+## Test Coverage
+
+### Security Core (`test_security.py`)
+- ✅ Password hashing with `security_hash_password()`
+- ✅ Password verification with `security_verify_password()`
+- ✅ JWT constants validation
+- ✅ Edge cases (special characters, unicode, long passwords)
+- ✅ Password consistency and security
+
+### Authentication (`test_auth.py`)
+- ✅ JWT token creation and validation
+- ✅ User authentication flow
+- ✅ Anonymous user handling
+- ✅ Token expiry and validation
+- ✅ Error handling for invalid tokens
+- ✅ Settings and configuration validation
+
+### RBAC (`test_rbac.py`)
+- ✅ Public element authorization
+- ✅ User author verification
+- ✅ Role-based permissions
+- ✅ Organization admin status
+- ✅ Combined roles and authorship
+- ✅ Anonymous user restrictions
+
+### RBAC Utils (`test_rbac_utils.py`)
+- ✅ Element type detection for all supported types
+- ✅ Singular form conversion
+- ✅ ID identifier generation
+- ✅ Edge cases and error handling
+- ✅ Consistency validation
+
+### Feature Usage (`test_features_utils.py`)
+- ✅ Feature limit checking
+- ✅ Usage tracking (increase/decrease)
+- ✅ Redis integration
+- ✅ Organization configuration validation
+- ✅ Unlimited feature handling
+- ✅ Error handling for missing configs
+
+## Running the Tests
+
+### Run All Security Tests
+```bash
+# From the project root
+pytest src/tests/security/ -v
+
+# Run with coverage
+pytest src/tests/security/ --cov=src.security --cov-report=html
+```
+
+### Run Specific Test Files
+```bash
+# Run only core security tests
+pytest src/tests/security/test_security.py -v
+
+# Run only authentication tests
+pytest src/tests/security/test_auth.py -v
+
+# Run only RBAC tests
+pytest src/tests/security/test_rbac.py -v
+
+# Run only feature usage tests
+pytest src/tests/security/test_features_utils.py -v
+```
+
+### Run Comprehensive Tests
+```bash
+# Run the comprehensive test suite
+pytest src/tests/security/test_security_all.py -v
+```
+
+## Test Dependencies
+
+The tests use the following dependencies:
+- `pytest` - Testing framework
+- `pytest-asyncio` - Async test support
+- `unittest.mock` - Mocking and patching
+- `fastapi` - HTTP exception testing
+- `sqlmodel` - Database session mocking
+
+## Mock Strategy
+
+The tests use comprehensive mocking to isolate the security functionality:
+
+1. **Database Sessions** - Mocked to avoid actual database connections
+2. **Redis Connections** - Mocked to avoid actual Redis dependencies
+3. **External Services** - Mocked to test error conditions
+4. **Configuration** - Mocked to test different config scenarios
+
+## Test Patterns
+
+### Async Testing
+All async functions are properly tested with `@pytest.mark.asyncio` decorators.
+
+### Error Handling
+Tests verify that appropriate HTTP exceptions are raised with correct status codes and messages.
+
+### Edge Cases
+Tests cover edge cases like:
+- Empty or null values
+- Invalid UUIDs
+- Disabled features
+- Missing configurations
+- Network failures
+
+### Type Safety
+Tests ensure type safety by using proper type annotations and handling type checking errors.
+
+## Adding New Tests
+
+When adding new security functionality:
+
+1. **Create a new test file** following the naming convention `test_<module_name>.py`
+2. **Add comprehensive test cases** covering success, failure, and edge cases
+3. **Use proper mocking** to isolate the functionality being tested
+4. **Add async support** if the function is async
+5. **Update this README** to document the new tests
+
+## Test Data
+
+The tests use mock data that represents realistic scenarios:
+- Mock users with different permission levels
+- Mock organizations with various configurations
+- Mock resources with different access patterns
+- Mock Redis usage data
+
+## Continuous Integration
+
+These tests are designed to run in CI/CD pipelines and provide:
+- Fast execution (no real database/Redis connections)
+- Comprehensive coverage of security functionality
+- Clear error messages for debugging
+- Reliable results across different environments
+
+## Security Considerations
+
+The tests are designed to validate security without exposing sensitive information:
+- No real passwords or tokens in test data
+- Mocked authentication flows
+- Isolated testing of security functions
+- No actual encryption/decryption of sensitive data
+
+## Contributing
+
+When contributing to security tests:
+
+1. Follow the existing patterns and conventions
+2. Ensure all edge cases are covered
+3. Use descriptive test names and docstrings
+4. Add appropriate error handling tests
+5. Update documentation as needed
