Why does Laravel Livewire test with PHPUnit return a NotFoundHttpException when API returns all User records?

I'm having trouble running a test on my API that returns all records from the user model. It's simple. The goal is to retrieve all data from this model. It is working fine both in the browser, in any mode, and in Postman. It always returns the data as JSON. Perfect. That's it.
I created both the tests and controllers with Livewire. I'm using the latest version of Laravel, Livewire, etc.
I'll share with you guys, the code of the controller that works perfectly, as well as the test code, my routes file, etc.
First, here's the error message that appears in my test.

I have already changed the order of routes, I have placed the route in the routes/web.php file. I have cleared the config:clear, cache, etc. I have used the named route, I have undone the named route.
I have tested it in Postman and in any browser. It works.
It is not a Unit test. It is a Feature Test.
It should return the status 200, and the test should not fail with the 404 error.

Please Help.

My Controller File: app/Http/Livewire/Api/ApiBuzCard.php

      return response($users, 200);
    }

My Route File: routes/api.php

<?php

use App\Http\Livewire\Api\ApiBuzCard;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Route;

Route::get('users', [ApiBuzCard::class, 'getAllUsers'])->name('api.users');

Route::middleware('auth:sanctum')
    ->get('/user', function (Request $request) {
        return $request->user();
    });

Route::get('user/{id}', [ApiBuzCard::class, 'getUser']);

Route::post('users', [ApiBuzCard::class, 'createUser'])
    ->middleware('api');
Route::put('user/{id}', [ApiBuzCard::class, 'updateUser'])
    ->middleware('api');
Route::delete('user/{id}', [ApiBuzCard::class, 'deleteUser'])
    ->middleware('api');

My Test File tests/Feature/ApiBuzCardTest.php

<?php

namespace Tests\Feature\Livewire\Api;

use App\Http\Livewire\Api\ApiBuzCard;
use App\Models\User;
use Livewire\Livewire;
use Tests\TestCase;

class ApiBuzCardTest extends TestCase
{
    /** @test */
    public function the_api_return_all_users()
    {
        $this->withoutExceptionHandling();

        $user = User::factory()->create();

        $response = $this->get('/api/users');
        $response->assertStatus(200);
    }

I found the solution on the link below. The User Sergiu17 suggested that the problem was the following configuration in my phpunit.xml file:

<server name="APP_URL" value="http://devlab03.mshome.net/virtual-card"/>

It needs to be changed to <env name="APP_URL" value="https://localhost"/>
Although I couldn't find anything in the official documentation, I believe that the Laravel testing environment can only work with this configuration on localhost.
Thank you.
