ShouldCallParentMethodsRector

PHPUnit based tests should call parent methods (setUp, tearDown)

 namespace Drupal\Tests\Rector\Deprecation\PHPUnit\ShouldCallParentMethodsRector\fixture;

 use Drupal\KernelTests\KernelTestBase;

 final class SetupVoidTest extends KernelTestBase {

     protected function setUp(): void
     {
+        parent::setUp();
         $test = 'doing things';
     }

     protected function tearDown(): void
     {
+        parent::tearDown();
         $test = 'doing things';
     }

 }

Configure your rector.php:

<?php

use DrupalRector\Rector\PHPUnit\ShouldCallParentMethodsRector;
use Rector\Config\RectorConfig;

return RectorConfig::configure()
    ->withRules([
        ShouldCallParentMethodsRector::class,
    ]);
