Problems with Unit Testing - HTTP Feature Testing - CI4

Hello, i'm trying to make a simple test using 'HTTP Feature testing' as described in Documentation. But, after hours of trying I couldn't achieve it.

This is my implementation class:

PHP Code:

<?php

namespace App\Controllers;

//use App\Libraries\Traits\ExtendedController;
use CodeIgniter\Controller;

class Home extends Controller
{
   // use ExtendedController;

    public function index()
    {
        return view('welcome_message');
    }

} 


And this is my Test class:

PHP Code:

<?php
namespace Tests;

use CodeIgniter\Test\FeatureTestCase;

class TestHome extends FeatureTestCase
{

    public function setUp()
    {
        parent::setUp();
    }

    public function tearDown()
    {
        parent::tearDown();
    }

    public function testIndex()
    {
        $result = $this->call('get', site_url());
        $this->assertSee('Welcome to CodeIgniter');
    }
} 


And this is the error thrown:

Code:

There was 1 error:

In my phpunit.xml, i've defined my env app.baseUrl as:    

Code:

<php>
       <env name="app.baseURL" value="http://ci4.extctrl.docker:8080/"/>
