Full stack testing in web development refers to testing all layers of a web application — from the front-end (client side) to the back-end (server side), and sometimes including the database and external services. The goal is to ensure that the entire system works together as expected.

In full stack application testing, key layers refer to the different parts of the application that should be tested to ensure the entire system works correctly. Here are the main layers:

1. Unit Testing Layer

  • Purpose: Tests individual components or functions.

  • Focus: Logic correctness at the smallest testable parts (e.g., functions, methods).

  • Tools: Jest, Mocha, JUnit, Pay Test.

2. Integration Testing Layer

  • Purpose: Tests interactions between modules or services.

  • Focus: Ensures components work together correctly (e.g., database calls, API connections).

  • Tools: Postman, Super Test, N Unit, pay test- Django.

3. API Testing Layer

  • Purpose: Tests the backend API endpoints.

  • Focus: Verifies request/response formats, status codes, data handling, and security.

  • Tools: Postman, REST Assured, Insomnia, Playwright (for API + UI).

4. End-to-End (E2E) Testing Layer

  • Purpose: Simulates real user scenarios.

  • Focus: Full user flow from frontend to backend (e.g., login, checkout).

  • Tools: Playwright, Cypress, Selenium.

5. UI Testing Layer

  • Purpose: Tests the frontend user interface.

  • Focus: Layout, styling, user interactions, responsiveness.

  • Tools: Playwright, Cypress, Selenium, Percy (for visual testing).

6. Performance & Load Testing Layer
