Suppressed deprecations not included in baseline when ignoreSuppressionOfDeprecations is true

[winterwald]

Q	A
PHPUnit version	11.1.3
PHP version	8.3.7
Installation Method	Composer

Summary

I encountered unexpected behavior when using the Baseline Generator with suppressed deprecations. In my project, deprecation notices are suppressed using @trigger_error('This is a test deprecation', E_USER_DEPRECATED);. When configuring PHPUnit with ignoreSuppressionOfDeprecations="true", I expected suppressed deprecations to be included in the generated baseline file. However, these suppressed deprecations are not included in the baseline. Consequently, rerunning PHPUnit with that baseline fails because the suppressed deprecations are still triggered.

But the deprecations end up in baseline if I change differen attribute ignoreSuppressionOfPhpWarnings="true".

Current behavior

Suppressed deprecations are not included in the baseline file, even with ignoreSuppressionOfPhpWarnings="true" added to the phpunit/source in PHPUnit configuration file.

How to reproduce

I set up an example project using only PHPUnit 11.1.0 to demonstrate the issue.

You can find it here: https://github.com/winterwald/phpunit-baseline-example

Refer to the README file for additional details.

Expected behavior

If I add ignoreSuppressionOfDeprecations="true" to phpunit/source in configuration file then suppressed deprecations should end up in baseline file.

I tried to resolve the issue for PHPUnit 10.5 (oldest supported version having baseline support) myself: #5848
