+# Plane Tests
+
+This directory contains tests for the Plane application. The tests are organized using pytest.
+
+## Test Structure
+
+Tests are organized into the following categories:
+
+- **Unit tests**: Test individual functions or classes in isolation.
+- **Contract tests**: Test interactions between components and verify API contracts are fulfilled.
+  - **API tests**: Test the external API endpoints (under `/api/v1/`).
+  - **App tests**: Test the web application API endpoints (under `/api/`).
+- **Smoke tests**: Basic tests to verify that the application runs correctly.
+
+## API vs App Endpoints
+
+Plane has two types of API endpoints:
+
+1. **External API** (`plane.api`):
+   - Available at `/api/v1/` endpoint
+   - Uses API key authentication (X-Api-Key header)
+   - Designed for external API contracts and third-party access
+   - Tests use the `api_key_client` fixture for authentication
+   - Test files are in `contract/api/`
+
+2. **Web App API** (`plane.app`):
+   - Available at `/api/` endpoint
+   - Uses session-based authentication (CSRF disabled)
+   - Designed for the web application frontend
+   - Tests use the `session_client` fixture for authentication
+   - Test files are in `contract/app/`
+
+## Running Tests
+
+To run all tests:
+
+```bash
+python -m pytest
+```
+
+To run specific test categories:
+
+```bash
+# Run unit tests
+python -m pytest plane/tests/unit/
+
+# Run API contract tests
+python -m pytest plane/tests/contract/api/
+
+# Run App contract tests
+python -m pytest plane/tests/contract/app/
+
+# Run smoke tests
+python -m pytest plane/tests/smoke/
+```
+
+For convenience, we also provide a helper script:
+
+```bash
+# Run all tests
+./run_tests.py
+
+# Run only unit tests
+./run_tests.py -u
+
+# Run contract tests with coverage report
+./run_tests.py -c -o
+
+# Run tests in parallel
+./run_tests.py -p
+```
+
+## Fixtures
+
+The following fixtures are available for testing:
+
+- `api_client`: Unauthenticated API client
+- `create_user`: Creates a test user
+- `api_token`: API token for the test user
+- `api_key_client`: API client with API key authentication (for external API tests)
+- `session_client`: API client with session authentication (for app API tests)
+- `plane_server`: Live Django test server for HTTP-based smoke tests
+
+## Writing Tests
+
+When writing tests, follow these guidelines:
+
+1. Place tests in the appropriate directory based on their type.
+2. Use the correct client fixture based on the API being tested:
+   - For external API (`/api/v1/`), use `api_key_client`
+   - For web app API (`/api/`), use `session_client`
+   - For smoke tests with real HTTP, use `plane_server`
+3. Use the correct URL namespace when reverse-resolving URLs:
+   - For external API, use `reverse("api:endpoint_name")`  
+   - For web app API, use `reverse("endpoint_name")`
+4. Add the `@pytest.mark.django_db` decorator to tests that interact with the database.
+5. Add the appropriate markers (`@pytest.mark.contract`, etc.) to categorize tests.
+
+## Test Fixtures
+
+Common fixtures are defined in:
+
+- `conftest.py`: General fixtures for authentication, database access, etc.
+- `conftest_external.py`: Fixtures for external services (Redis, Elasticsearch, Celery, MongoDB)
+- `factories.py`: Test factories for easy model instance creation
+
+## Best Practices
+
+When writing tests, follow these guidelines:
+
+1. **Use pytest's assert syntax** instead of Django's `self.assert*` methods.
+2. **Add markers to categorize tests**:
+   ```python
+   @pytest.mark.unit
+   @pytest.mark.contract
+   @pytest.mark.smoke
+   ```
+3. **Use fixtures instead of setUp/tearDown methods** for cleaner, more reusable test code.
+4. **Mock external dependencies** with the provided fixtures to avoid external service dependencies.
+5. **Write focused tests** that verify one specific behavior or edge case.
+6. **Keep test files small and organized** by logical components or endpoints.
+7. **Target 90% code coverage** for models, serializers, and business logic.
+
+## External Dependencies
+
+Tests for components that interact with external services should:
+
+1. Use the `mock_redis`, `mock_elasticsearch`, `mock_mongodb`, and `mock_celery` fixtures for unit and most contract tests.
+2. For more comprehensive contract tests, use Docker-based test containers (optional).
+
+## Coverage Reports
+
+Generate a coverage report with:
+
+```bash
+python -m pytest --cov=plane --cov-report=term --cov-report=html
+```
+
+This creates an HTML report in the `htmlcov/` directory.
+
+## Migration from Old Tests
+
+Some tests are still in the old format in the `api/` directory. These need to be migrated to the new contract test structure in the appropriate directories.

+# Testing Guide for Plane
+
+This guide explains how to write tests for Plane using our pytest-based testing strategy.
+
+## Test Categories
+
+We divide tests into three categories:
+
+1. **Unit Tests**: Testing individual components in isolation.
+2. **Contract Tests**: Testing API endpoints and verifying contracts between components.
+3. **Smoke Tests**: Basic end-to-end tests for critical flows.
+
+## Writing Unit Tests
+
+Unit tests should be placed in the appropriate directory under `tests/unit/` depending on what you're testing:
+
+- `tests/unit/models/` - For model tests
+- `tests/unit/serializers/` - For serializer tests
+- `tests/unit/utils/` - For utility function tests
+
+### Example Unit Test:
+
+```python
+import pytest
+from plane.api.serializers import MySerializer
+
+@pytest.mark.unit
+class TestMySerializer:
+    def test_serializer_valid_data(self):
+        # Create input data
+        data = {"field1": "value1", "field2": 42}
+        
+        # Initialize the serializer
+        serializer = MySerializer(data=data)
+        
+        # Validate
+        assert serializer.is_valid()
+        
+        # Check validated data
+        assert serializer.validated_data["field1"] == "value1"
+        assert serializer.validated_data["field2"] == 42
+```
+
+## Writing Contract Tests
+
+Contract tests should be placed in `tests/contract/api/` or `tests/contract/app/` directories and should test the API endpoints.
+
+### Example Contract Test:
+
+```python
+import pytest
+from django.urls import reverse
+from rest_framework import status
+
+@pytest.mark.contract
+class TestMyEndpoint:
+    @pytest.mark.django_db
+    def test_my_endpoint_get(self, auth_client):
+        # Get the URL
+        url = reverse("my-endpoint")
+        
+        # Make request
+        response = auth_client.get(url)
+        
+        # Check response
+        assert response.status_code == status.HTTP_200_OK
+        assert "data" in response.data
+```
+
+## Writing Smoke Tests
+
+Smoke tests should be placed in `tests/smoke/` directory and use the `plane_server` fixture to test against a real HTTP server.
+
+### Example Smoke Test:
+
+```python
+import pytest
+import requests
+
+@pytest.mark.smoke
+class TestCriticalFlow:
+    @pytest.mark.django_db
+    def test_login_flow(self, plane_server, create_user, user_data):
+        # Get login URL
+        url = f"{plane_server.url}/api/auth/signin/"
+        
+        # Test login
+        response = requests.post(
+            url, 
+            json={
+                "email": user_data["email"],
+                "password": user_data["password"]
+            }
+        )
+        
+        # Verify
+        assert response.status_code == 200
+        data = response.json()
+        assert "access_token" in data
+```
+
+## Useful Fixtures
+
+Our test setup provides several useful fixtures:
+
+1. `api_client`: An unauthenticated DRF APIClient
+2. `api_key_client`: API client with API key authentication (for external API tests)
+3. `session_client`: API client with session authentication (for web app API tests)
+4. `create_user`: Creates and returns a test user
+5. `mock_redis`: Mocks Redis interactions
+6. `mock_elasticsearch`: Mocks Elasticsearch interactions
+7. `mock_celery`: Mocks Celery task execution
+
+## Using Factory Boy
+
+For more complex test data setup, use the provided factories:
+
+```python
+from plane.tests.factories import UserFactory, WorkspaceFactory
+
+# Create a user
+user = UserFactory()
+
+# Create a workspace with a specific owner
+workspace = WorkspaceFactory(owner=user)
+
+# Create multiple objects
+users = UserFactory.create_batch(5)
+```
+
+## Running Tests
+
+Use pytest to run tests:
+
+```bash
+# Run all tests
+python -m pytest
+
+# Run only unit tests with coverage
+python -m pytest -m unit --cov=plane
+```
+
+## Best Practices
+
+1. **Keep tests small and focused** - Each test should verify one specific behavior.
+2. **Use markers** - Always add appropriate markers (`@pytest.mark.unit`, etc.).
+3. **Mock external dependencies** - Use the provided mock fixtures.
+4. **Use factories** - For complex data setup, use factories.
+5. **Don't test the framework** - Focus on testing your business logic, not Django/DRF itself.
+6. **Write readable assertions** - Use plain `assert` statements with clear messaging.
+7. **Focus on coverage** - Aim for ≥90% code coverage for critical components.
