Type error on executing functional tests for typo3DatabasePort, must be integer

[kanow]

What are you trying to achieve?

Execute functional tests.

What do you get instead?

Error:

TypeError: mysqli::real_connect(): Argument #5 ($port) must be of type ?int, string given

How to reproduce the issue?

Not sure about a specific environment settings to reproduce that error. We ware executing functional tests in our local dev environment. Tests are excuted in docker container with:

vendor/bin/phpunit -c vendor/undkonsorten/our-package-folder/Tests/FunctionalTests.xml

We are settings typo3DatabasePort=3306 as environment variable in our test container.

Additional information you would like to provide?

If I cast $databasePort to int in line 476 of project/vendor/typo3/testing-framework/Classes/Core/Testbase.php then the error is gone.

Specify some data of the environment

• TYPO3 testing framework version: 8.2.3
• TYPO3 version: 13.3-dev-main
• TYPO3 installation type: composer
• PHP version: 8.2
• Web server used + version: apache

Thanks for the report. Can you plese provide more insights like a stack trace leading to this ? TYPO3 Connection Pool converts the port to an integer. Stacktrace would help to identify things.
