Introduced by PHPUnit 10.0.12.

Current behavior

PHPUnit 10.0.12 by Sebastian Bergmann and contributors.

Runtime:       PHP 8.1.14
Configuration: /path/phpunit-10-test/phpunit.xml

.S                                                                  2 / 2 (100%)

An error occurred inside PHPUnit.

Message:  assert($this->currentTestCase !== null)
Location: /path/phpunit-10-test/vendor/phpunit/phpunit/src/TextUI/TestRunner.php:68

#0 /path/phpunit-10-test/vendor/phpunit/phpunit/src/TextUI/Application.php(142): PHPUnit\TextUI\TestRunner->run()
#1 /path/phpunit-10-test/vendor/phpunit/phpunit/phpunit(90): PHPUnit\TextUI\Application->run()
#2 /path/phpunit-10-test/vendor/bin/phpunit(123): include('...')
#3 {main}

How to reproduce

</phpunit>

tests/FooTest.php

<?php

declare(strict_types=1);

use PHPUnit\Framework\Attributes\RequiresPhpExtension;
use PHPUnit\Framework\Attributes\RunInSeparateProcess;
use PHPUnit\Framework\TestCase;

class FooTest extends TestCase
{
    public function testOne(): void
    {
        $this->assertTrue(true);
    }

    #[RunInSeparateProcess]
    #[RequiresPhpExtension('notinstalled')]
    public function testTwo(): void
    {
        $this->assertTrue(true);
    }
}

Expected behavior

PHPUnit 10.0.11 by Sebastian Bergmann and contributors.

Runtime:       PHP 8.1.14
Configuration: /path/phpunit-10-test/phpunit.xml

.S                                                                  2 / 2 (100%)

OK, but some tests were skipped!
Tests: 2, Assertions: 1, Skipped: 1.
