# 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.
