+  - Error handling
+
+## Running Tests
+
+### Using Frappe Test Runner
+```bash
+# Run all tests
+bench --site [site-name] run-tests --app jwt_auth
+
+# Run specific test file
+bench --site [site-name] run-tests jwt_auth.jwt_auth.doctype.jwt_auth_settings.test_jwt_auth_settings
+
+# Run specific test class
+bench --site [site-name] run-tests jwt_auth.tests.test_auth.TestJWTAuthUnit
+
+# Run with verbose output
+bench --site [site-name] run-tests --app jwt_auth --verbose
+```
+
+### Using pytest (if available)
+```bash
+# Run all tests
+pytest jwt_auth/tests/
+
+# Run specific test file
+pytest jwt_auth/tests/test_auth.py
+
+# Run with coverage
+pytest jwt_auth/tests/ --cov=jwt_auth
+```
+
+## Test Design Principles
+
+### 1. Frappe Conventions
+- Uses `frappe.tests.UnitTestCase` for unit tests
+- Uses `frappe.tests.IntegrationTestCase` for integration tests
+- Follows Frappe naming conventions and patterns
+- Properly handles test record dependencies
+
+### 2. No External Dependencies
+- All external API calls are mocked
+- Cloudflare Access interactions are simulated
+- No actual network requests are made during testing
+- JWT token validation uses mock keys and payloads
+
+### 3. Comprehensive Coverage
+- Tests all public methods and functions
+- Tests both success and failure scenarios
+- Tests edge cases and error conditions
+- Tests integration between components
+
+### 4. Isolation and Cleanup
+- Each test is isolated and doesn't affect others
+- Proper setup and teardown methods
+- Test data is cleaned up after each test
+- Mock objects are reset between tests
+
+## Mock Strategy
+
+### External APIs
+- **Cloudflare JWKS endpoint**: Mocked with realistic response structure
+- **JWT token validation**: Mocked with various token scenarios
+- **Network requests**: All `requests.get()` calls are mocked
+
+### Frappe Framework
+- **frappe.local**: Mocked for request/session simulation
+- **frappe.db**: Mocked for database operations
+- **frappe.cache**: Mocked for caching operations
+- **Document operations**: Mocked for create/read/update/delete
+
+### JWT Library
+- **jwt.decode()**: Mocked to return various claim scenarios
+- **jwt.algorithms.RSAAlgorithm**: Mocked for key handling
+- **JWT exceptions**: Simulated for error testing
+
+## Test Data
+
+### Valid JWT Claims
+```python
+{
+    "aud": ["test-secret"],
+    "email": "test@example.com",
+    "exp": <future_timestamp>,
+    "iat": <current_timestamp>,
+    "iss": "https://test-team.cloudflareaccess.com",
+    "sub": "1234567890",
+    "common_name": "test@example.com"
+}
+```
+
+### Cloudflare JWKS Response
+```python
+{
+    "keys": [
+        {
+            "alg": "RS256",
+            "kty": "RSA",
+            "use": "sig",
+            "kid": "cloudflare-key-1",
+            "n": "example_n_parameter",
+            "e": "AQAB"
+        }
+    ]
+}
+```
+
+## Test Scenarios Covered
+
+### Authentication Flow
+1. Valid JWT token authentication
+2. Expired JWT token handling
+3. Invalid audience token handling
+4. Missing token scenarios
+5. User registration with/without existing contacts
+6. Login/logout redirects
+
+### Provider Integration
+1. Cloudflare URL generation
+2. JWKS key retrieval
+3. Multiple key handling
+4. Network error handling
+5. URL encoding edge cases
+
+### Settings Validation
+1. Mandatory field validation
+2. Conditional field requirements
+3. Password field handling
+4. Default value verification
+
+### Hooks Functionality
+1. Contact field synchronization
+2. Contact renaming logic
+3. User profile updates
+4. Error page rendering
+
+## Contributing
+
+When adding new functionality to JWT Auth:
+
+1. **Add corresponding tests** for new functions/methods
+2. **Update existing tests** if changing behavior
+3. **Add mock scenarios** for new external dependencies
+4. **Test both success and failure paths**
+5. **Follow existing naming conventions**
+6. **Add docstrings** explaining test purpose
+7. **Update this README** if adding new test categories
+
+## Common Test Patterns
+
+### Mocking External Calls
+```python
+@patch('jwt_auth.auth.requests.get')
+def test_external_api(self, mock_requests):
+    mock_requests.return_value.json.return_value = {...}
+    # Test implementation
+```
+
+### Testing JWT Validation
+```python
+@patch('jwt_auth.auth.jwt.decode')
+def test_jwt_validation(self, mock_jwt_decode):
+    mock_jwt_decode.return_value = {'email': 'test@example.com'}
+    # Test implementation
+```
+
+### Testing Frappe Documents
+```python
+def test_document_operation(self):
+    doc = frappe.get_doc('DocType', 'name')
+    # Modify doc
+    doc.save()
+    # Assert changes
+```
