AssertOptionSelectedRector

Fixes deprecated AssertLegacyTrait::assertOptionSelected() calls

-$this->assertOptionSelected('options', 2);
+$this->assertTrue($this->assertSession()->optionExists('options', 2)->hasAttribute('selected'));

Configure your rector.php:

<?php

use DrupalRector\Drupal9\Rector\Deprecation\AssertOptionSelectedRector;
use Rector\Config\RectorConfig;

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