Laravel 5.4 - Disable Exception Handling for tests, with reminder to enable it when green

TestCase.php

<?php

namespace Tests;

use App\Exceptions\Handler;
use Exception;
use Illuminate\Contracts\Debug\ExceptionHandler;
use Illuminate\Foundation\Testing\TestCase as BaseTestCase;

abstract class TestCase extends BaseTestCase
{
    use CreatesApplication;

    private $isExceptionHandlingDisabled = false;

    protected function tearDown()
    {
        parent::tearDown();

        // Reminder to remove $this->disableExceptionHandling() from your test once it passes.
        // Marks the test as incomplete until it's removed.
        if ($this->isExceptionHandlingDisabled) {
            $this->markTestIncomplete('Exception handling is disabled.');
        }
    }

    protected function disableExceptionHandling()
    {
        $this->isExceptionHandlingDisabled = true;

        // Shout out to Adam Wathan (@adamwathan) for this
        $this->app->instance(ExceptionHandler::class, new class extends Handler {
            public function __construct() {}
            public function report(Exception $e) {}
            public function render($request, Exception $e) {
                throw $e;
            }
        });
    }
}

Is this needed for Laravel 10? I am doing Interia / Vue / Laravel tests & following an old series of Jeffreys on Laracast.
However, I feel that doing the tests doesn't require exception handling. 🔢
