Something wrong with my first test file?

Hello, all my tests seem to be failing no matter what and im wondering if perhaps something is wrong with the code below.

Following this tutorial: https://laracasts.com/series/build-a-voting-app/episodes/10 I did everything as André himself said, we had to first and foremost create an idea via php artisan make:test IdeaShowTest command, afterwards uncomment this portion: <server name="DB_CONNECTION" value="sqlite"/> from phpunit.xml and then write the following code below:

<?php

namespace Tests\Feature;

use Tests\TestCase;
use App\Models\Idea;
use Illuminate\Foundation\Testing\WithFaker;
use Illuminate\Foundation\Testing\RefreshDatabase;

class ShowIdeasTest extends TestCase
{
    use RefreshDatabase;

    public function list_of_ideas_shows_on_main_page()
    {
        $ideaOne = Idea::factory()->create([
            'title' => 'My First Idea',
            'description' => 'Description of my first idea',
        ]);

        $ideaTwo = Idea::factory()->create([
            'title' => 'My Second Idea',
            'description' => 'Description of my second idea',
        ]);

        $response = $this->get(route('idea.index'));

        $response->assertSuccessfull();
        $response->assertSee($ideaOne->title);
        $response->assertSee($ideaOne->description);
        $response->assertSee($ideaTwo->title);
        $response->assertSee($ideaTwo->description);
    }
}

But as it turns out it's not working and I don't know why. I'll share with you a portion from the messages that I got, in total there should be 15 errors and it's obvious to me, seems like it wants to know about my database but Im at a loss here since this is my first time checking out the tests functionality within Laravel, so was there a database prerequisite other than uncommenting that line on phpunit.xml? Should I had added a new env var ? I read through the docs but couldn't find anything worth mentioning.. Please let me know, thanks!
