Writing tests for a Python-based full stack app involves testing both backend and frontend components to ensure the application functions as expected. Here's a structured approach:

1. Unit Tests (Backend):
   Test individual functions, classes, and modules using frameworks like unittest or pytest. Mock external dependencies to isolate logic.

   • Example: Testing a function that processes user input or interacts with a database model.

2. Integration Tests:
   Verify how components work together, such as database access, APIs, and third-party services.

   • Use tools like pytest with test databases or Docker for environment consistency.

3. API Tests:
   Test RESTful or GraphQL endpoints using requests, pytest, or tools like Postman and pytest-django/Flask-Testing.

   • Validate response codes, headers, and payloads.

4. Frontend Unit Tests:
   If using a frontend framework (e.g., React), use Jest and React Testing Library to test components, state changes, and rendering logic.

5. End-to-End (E2E) Tests:
   Simulate real user interactions using tools like Selenium, Playwright, or Cypress. These test the entire stack from the browser to the database.

6. Test Data Management:
   Use fixtures or factories (pytest fixtures, Factory Boy) to create predictable and reusable test data.

7. Continuous Integration:
   Automate test execution in CI pipelines (e.g., GitHub Actions, GitLab CI) to ensure code quality with every change.

A solid testing strategy combines these layers to catch bugs early, improve confidence, and support fast, safe deployments.
