Create unit tests

[firepenguindisopanda]

As a backend developer
I need to create unit tests for the backend API
So that I can ensure the functionality and reliability of the application

Details and Assumptions

• Unit tests will focus on individual components of the backend (controllers, models) to ensure each part behaves as expected.
• Testing frameworks and libraries such as Jest, Mocha, or Supertest will be utilized for testing.
• A testing database will be set up to isolate tests from production data.
• Test cases will be written to cover both successful and failure scenarios.

Acceptance Criteria

Given the backend API is implemented
When I run the unit tests
Then all unit tests should pass without errors
