Write Unit Tests for backend

---

Tasks

1. Set Up Testing Framework:

   • Install and configure pytest and pytest-flask for testing the application.

2. Write Unit Tests for Routes:

   • Test each endpoint for expected behavior (e.g., HTTP status codes, JSON response structure, query parameters, and path parameters).

3. Test Dependencies:

   • Mock external dependencies (e.g., databases, third-party APIs) using unittest.mock or pytest-mock.

4. Test Application Context:

   • Ensure proper testing of the Flask app context and configurations.

5. Organize Tests:

   • Place test files in the tests/ directory.
   • Use meaningful test function names and group related tests into separate files.

6. Document Test Instructions:

   • Update the project README or contributing guide with steps to run tests locally.

Acceptance Criteria

• All routes have at least one unit test.
• External dependencies are mocked and tested effectively.
• Tests are structured, organized, and easy to maintain.
• All tests pass when executed using pytest.
