Test TDD lesson 1 No tests found in class "Tests\Feature\ProjectsTest".

I'm following this first lesson -> https://laracasts.com/series/build-a-laravel-app-with-tdd/episodes/2?autoplay=true

I wrote this test:

namespace Tests\Feature;

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

class ProjectsTest extends TestCase
{
    use WithFaker, RefreshDatabase;

    public function a_user_can_create_a_project()
    {

        $this->withoutExceptionHandling();

        $attributes = [
            'title' => $this->faker->sentence,
            'description' => $this->faker->paragraph,
        ];

        $this->post(['/projects', $attributes

        ]);

        $this->assertDatabaseHas('projects',$attributes);
    }
}

in the phpunit.xml file I changed so:

<php>
    <server name="APP_ENV" value="testing"/>
    <server name="BCRYPT_ROUNDS" value="4"/>
    <server name="CACHE_DRIVER" value="array"/>
     <server name="DB_CONNECTION" value="sqlite"/>
     <server name="DB_DATABASE" value=":memory:"/>
    <server name="MAIL_MAILER" value="array"/>
    <server name="QUEUE_CONNECTION" value="sync"/>
    <server name="SESSION_DRIVER" value="array"/>
    <server name="TELESCOPE_ENABLED" value="false"/>
</php>

when i run the test i get this:

vendor/bin/phpunit tests/Feature/ProjectsTest.php
