My first test....

I was going to write my first test ever and failed already... from the docs I found this piece and saved it at tests/app/Libraries/fooTest.php

PHP Code:

<?php

namespace App\Libraries;

use CodeIgniter\Test\CIUnitTestCase;

class FooTest extends CIUnitTestCase
{
    public function testFooNotBar()
    {
        $response = $this->get('/');
    }
} 


When I run the test now via 'vendor/bin/phpunit' I get the error message

Code:

There was 1 error:

1) App\Libraries\FooTest::testFooNotBar
Error: Call to undefined method App\Libraries\FooTest::get()

/var/www/html/bofewo/web/tests/app/Libraries/fooTest.php:11

So apparently I am missing something but not experienced enough to know what. Can someone point me the right direction please?

Feature testing requires that all of your test classes use the CodeIgniter\Test\DatabaseTestTrait and CodeIgniter\Test\FeatureTestTrait traits.
