Allow to limit the reporting of deprecations, notices, and warnings to specified directories

[sebastianbergmann]

As of PHPUnit 10.0, the test runner prints D, N, and W, respectively, for tests that execute code which triggers E_DEPRECATED, E_USER_DEPRECATED, E_NOTICE, E_USER_NOTICE, E_STRICT, E_WARNING, or E_USER_WARNING events.

Detailed information (which notices was triggered where, for instance) is only printed when --display-deprecations, --display-notices, or --display-warnings is used.

The test runner should support limiting the reporting of deprecations, notices, and warnings to "your code", excluding code from directories such as vendor, for example.

This depends on #5294.

Commenting here as I was notified by this superseding another issue I opened some time ago: #5191

The test runner should support limiting the reporting of deprecations, notices, and warnings to "your code", excluding code from directories such as vendor, for example.

I actually think it makes more sense the other way around. It can be useful to be notified about the usage of deprecated third party code, as it's easy for the deprecations to be unknown until it's "too" late.

As per the project's own code, the usage of deprecated symbols is probably known and there's plans to stop using them. It is also likely they were deprecated just to avoid using them by mistake in new code, but you don't need to be warned about your own code.

But of course I'm biased here and probably missing the big picture 😅
