laravel unit testing not giving right response with “phpunit”

Question

I need to make unit tests for my laravel app. So far I have started to code the test, but when i ran it it returned not what i expected, so far i have not seen this anywhere on the internet. So I must be doing somethng stupid or missing something, right?

my testing class in tests/tests.php

<?php

use Illuminate\Foundation\Testing\WithoutMiddleware;
use Illuminate\Foundation\Testing\DatabaseMigrations;
use Illuminate\Foundation\Testing\DatabaseTransactions;

class Tests extends TestCase
{
public function testLoad(){
    $this->call('GET', '/');

    $this->assertResponseOk();

    $response = $this->action('GET', 'mainController@load');

    $this->visit('/')
         ->see('Todo seznam');

    $this->assertViewHas('tasks');
}

public function dbTest(){
    $this->call('GET', '/delete');

    $this->assertHasOldInput();
}
}

so I presumed i have to install phpunit (I'm on ubuntu 16.04) and then I ran it in root of my project with "phpunit" like everyone else who succeded but got this result:

a bunch of files i have done no changes to whasoever.

Then i figured i would just make a new project and phpunit there but the result was the same, but even more errors.
