Preconditions and environment

• Magento 2.4.9 Alpha 3
• Anything else that would help a developer reproduce the bug

Steps to reproduce

Take a freshly installed Magento 2.4.9 Alpha 3, and try to run an integration test. I've run this test:

class ExampleTest extends \PHPUnit\Framework\TestCase
{
    /**
     * The only goal of this test is to check if test can be run successful.
     */
    public function testSuccess()
    {
        $this->assertTrue(true);
    }

    /**
     * @magentoConfigFixture current_store general/store_information/name Magento 2 test store
     */
    public function testCanUseConfigFixture(): void
    {
        $result = ObjectManager::getInstance()->get(ScopeConfigInterface::class)->getValue(
            'general/store_information/name',
            \Magento\Store\Model\ScopeInterface::SCOPE_STORE
        );

        $this->assertEquals('Magento 2 test store', $result);
    }
}

With this command:

cd /data/dev/tests/integration/ && ../../../vendor/bin/phpunit /data/vendor/michielgerritsen/exampletest/Test/Integration/ExampleTest.php

This module is nothing more than a composer.json, registration.php, a module.xml, and this test, all installed through Composer.

Expected result

I would expect that the test runs successfully.

Actual result

I'm getting this error:

Hello @michielgerritsen,

Thank you for your report and collaboration!

We have tried to reproduce the issue in both 2.4.9-alpha3 and the latest development branch i.e. 2.4-develop but the issue is not reproducible for us.

The integration test is successfully completed at our end. Please refer to the below screenshot and the attached module:

Issue40234.zip

Let us know if we missed anything.

Hello @engcom-Hotel,

It seems that running bin/magento setup:di:compile is the culprit. I took these steps:

• Set up a fresh Magento installation and run the install command.
• Install the module you provided through Composer (I'm not sure if this matters), run bin/magento module:enable.

Now the important steps:

Running the integration tests will run fine:

cd dev/tests/integration && ../../../vendor/bin/phpunit ../../../extensions/Issue40234/Test/Integration/ExampleTest.php

But the moment I run setup:di:compile the tests wil fail:

php bin/magento setup:di:compile && cd /var/www/html/dev/tests/integration && ../../../vendor/bin/phpunit ../../../extensions/Issue40234/Test/Integration/ExampleTest.php

I think, but I would have to investigate more, that this is caused by the fact that setup:di:compile generates the generated/metadata/global.php file. Because that file exists, this if statement never results true:
https://github.com/magento/magento2/blob/2.4-develop/lib/internal/Magento/Framework/App/ObjectManagerFactory.php#L139-L144

If I remove the generated/metadata/ folder, I can once again run the test successfully.
