phpunit doesn't display any errors

I started learn testing in Laravel but I have a little problem. So phpunit never display any errors. It's simple example

<?php

namespace Tests\Unit;

use Tests\TestCase;
use Illuminate\Foundation\Testing\RefreshDatabase;

class ExampleTest extends TestCase
{
    /**
     * A basic test example.
     *
     * @return void
     */
    public function testBasicTest()
    {
        $this->visit('/sdsdsdsd')->see('dasdadasdasd');

    }
}

I wrote phpunit in console but I doesn't any errors. Why?
