Self-review

• Verified that the GetAllUserPostViewModel correctly transforms GetAllUserPostDto data.
• Ensured getAllPosts() controller method receives userId, perPage, and currentPage properly and handles exceptions.
• Confirmed that all response formats match expected frontend structure.
• Unit tests were created and passed for both ViewModel and Controller.

• This test only checks the response type. Consider adding assertions to verify the JSON body structure (e.g., status, data, pagination metadata) to ensure the controller returns the expected payload.

$this->assertInstanceOf(JsonResponse::class, $response);

src/app/Post/Presentation/Controller/PostController.php:55

• The JsonResponse type is not imported at the top of the file, causing an undefined class error. Add use Illuminate\Http\JsonResponse;.

The controller maps each item with ->toArray() directly but never constructs the GetAllUserPostViewModel. To ensure proper mapping from DTO to view model, apply GetAllUserPostViewModel::build($item)->toArray() instead of calling toArray() on the raw item.

Suggested change

	fn($item) => $item->toArray(),
	fn($item) => GetAllUserPostViewModel::build($item)->toArray(),
