Summary
Call to undefined function CodeIgniter\Test\helper() for CIUnitTestCase

I'm trying codeigniter4 testing tutorial.
testing-feature

PHP Code:

// ci4_batches/batches/tests/app/Controllers/TestHome.php
<?php
namespace App;

use CodeIgniter\Router\Exceptions\RedirectException;
use CodeIgniter\Test\CIUnitTestCase;
use CodeIgniter\Test\ControllerTestTrait;
use CodeIgniter\Test\DatabaseTestTrait;
use Exception;

class TestHome extends CIUnitTestCase
{
    use DatabaseTestTrait;
    use ControllerTestTrait;
    
    protected function setUp(): void
    {
        parent::setUp();
        
        // $this->myClassMethod();
    }
    
    protected function tearDown(): void
    {
        parent::tearDown();
        
        // $this->anotherClassMethod();
    }
    
    /**
    * @throws RedirectException
    * @throws Exception
    */
    public function testIndex()
    {
        // Get a simple page
        $result = $this->call('get', '/');
        
        $result->assertOK();
    }
} 


phpStorm will be pop up this message.

Why can't I do it?

Did you ever get this to work?

The call method is defined in the CodeIgniter\Test\FeatureTestTrait trait but you didn't add it.

I found it while organizing past posts.
I can't remember exactly what I detail, but the reason I wasn't able to test with PHPStorm is probably that I didn't specify the interpreter as phpunit.

Thank you everyone.
