Description

Dependencies

• Symfony 7.2
• PHPUnit 11.5

Scenario

Given a PHPUnit test that invokes code that in turn invokes trigger_deprecation
(in my case it was the Constraints/Url constructor from symfony/validator but that doesn't really matter).

Also assume to have stopOnDeprecation="true" in your PHPUnit configuration.

Now if you run PHPUnit, it will exit once it hits the test that indirectly invokes trigger_deprecation, and while doing so will not give any indication what happened. It will look like everything went fine (no warnings, exit code 0).

Only if you run PHPUnit with --debug you will see something like this in the output:

Test Triggered Deprecation (namespace\of\Test::testMethod, issue triggered by third-party code, suppressed using operator)
Since symfony/validator 7.1: Not passing a value for the "requireTld" option to the Url constraint is deprecated. Its default value will change to "true".

trigger_error invoked by trigger_deprecation indeed uses the silence operator, so this explains the behavior.

Request

Document (on the symfony/deprecation-contracts GitHub page) how the package may affect PHPUnit test execution and what can be done to mitigate it (add <source ignoreSuppressionOfDeprecations="true"> to the PHPUnit configuration).

Maybe it's worth pursuing to change the behavior of PHPUnit there as well but I'm only concentrating on getting the current state documented here.
