TestSuite in events does not have proper name set

[pawelbaranski]

Q	A
PHPUnit version	10.5.41
PHP version	8.1.31
Installation Method	Composer

Summary

I am using extension that registers subscriber, subscriber implements LoadedSubscriber (tried also with ExecutionStartedSubscriber, same result).

Current behavior

Loaded event that I'm getting has TestSuite object with name set with path to my phpunit.xml file instead of the test suite name that I run

How to reproduce

create extension

<?php

namespace My\Tests\extension;

use PHPUnit\Runner\Extension\Extension;
use PHPUnit\Runner\Extension\Facade;
use PHPUnit\Runner\Extension\ParameterCollection;
use PHPUnit\TextUI\Configuration\Configuration;

class RegisterSubscribersExtension implements Extension
{
	public function bootstrap(Configuration $configuration, Facade $facade, ParameterCollection $parameters): void
	{
		$facade->registerSubscribers(
			new IntegrationTestBootstrapExtension(),
		);
	}
}

create subscriber

<?php

namespace My\Tests\extension;

use PHPUnit\Event\TestRunner\ExecutionStarted;
use PHPUnit\Event\TestSuite\Loaded;
use PHPUnit\Event\TestSuite\LoadedSubscriber;

class IntegrationTestBootstrapExtension implements LoadedSubscriber
{
	public function notify(Loaded $event): void
	{
		var_dump($event->testSuite()->name());die;
	}
}

in phpunit.xml

<extensions>
    <bootstrap class="My\Tests\extension\RegisterSubscribersExtension"/>
</extensions>
<testsuites>
    <testsuite name="unit-panel">
    ...
    </testsuite>
    ...
</testsuites>

run tests (I run them with composer)

scripts in composer.json (I got it in "panel" subdirectory, relative to phpunit.xml)

"unit-tests": [
    "export APP=panel; phpunit -c ../phpunit.xml --testsuite=unit-panel"
],

run , with output

> composer -d panel unit-tests
> export APP=panel; phpunit -c ../phpunit.xml --testsuite=unit-panel
PHPUnit 10.5.41 by Sebastian Bergmann and contributors.

Runtime:       PHP 8.1.31
Configuration: /home/dev/public_html/phpunit.xml

/home/dev/public_html/tests/extension/IntegrationTestBootstrapExtension.php:13:
string(37) "/home/dev/public_html/phpunit.xml"

Expected behavior

I'd expect the TestSuite object to have name "unit-panel", not a path to phpunit.xml
