[FEAT]: Retrieve Product Details

[theijhay]

Description:

Develop a backend API endpoint to allow logged-in users to retrieve the details of a specific product. This functionality is part of the product management system and requires user authentication.

Acceptance Criteria:

Endpoint security:

Only authenticated users can have access to the endpoint A user must have the appropriate permissions to access the endpoint Each request to the endpoint must include a valid authentication token in the

1. Retrieve Product Details:

• Method: GET
• URL: /api/v1/products/:id
• Request:
  • Headers:
  • Authorization: Bearer <JWT_token>
• Response: On successful retrieval:

  {
  "status": "success",
  "message": "Product details retrieved successfully",
  "status_code": 200,
  "data": {
    "id": 1,
    "name": "string",
    "price": 45.0
    "description": "string",
  }
  }

  On error (e.g., product not found):

  {
  "status": "error",
  "message": "Product not found",
  "status_code": 404
  }

  On error (e.g., unauthorized access):

  {
  "status": "error",
  "message": "Unauthorized access",
  "status_code": 401
  }

  Validation:

• Validate the JWT auth token.
• Validate that the id exists and the user is authorized to view the product.

Purpose: To provide a secure and authenticated endpoint for retrieving details of a specific product, ensuring only authorized users can access this information.

Expected Outcome: A fully functional backend API endpoint that allows logged-in users to retrieve product details, with proper validation and error handling.

Tasks:

• [x] Implement the GET endpoint to retrieve product details.
• [x] Validate inputs and handle errors appropriately.
• [x] Write unit tests for the endpoint to ensure it handles valid and invalid inputs correctly.

Test Scenarios:

1. Successful product retrieval: Verify that a logged-in user can retrieve product details with a valid product ID.
2. Product not found: Verify that the endpoint returns a 404 status code when the product does not exist.
3. Unauthorized access: Verify that the endpoint returns a 401 status code when the user is not authorized to view the product.
4. Validation error: Verify that the endpoint returns a 400 status code when required parameters are missing or incorrectly formatted.
