Enumerations cannot be targeted for code coverage

[doppynl]

Q	A
PHPUnit version	12.0.1
PHP version	8.4.2
Installation Method	Composer
Code coverage	XDebug 3.4.0

Summary

Unable to configure code coverage for Enums.

Current behavior

When configuring coverage or usage using coversClass or usesClass attributes it gives me the following error:
Class ..... is not a valid target for code coverage

I tried configuring coverage using coversNamespace but got a similar error.

How to reproduce

Create an Enum and try to configure coverage in a TestCase.

Expected behavior

I can configure coverage for an Enum on my TestCases.

Maybe with specific attributes like coversEnum and usesEnum, but the ...Class attributes might work just fine if they accept enums.

I keep forgetting that enumerations in PHP are more than just enumerations, sorry. Are you telling me that enumerations could be targetted with CoversClass and UsesClass in PHPUnit 10 and PHPUnit 11? If so, this would indeed be a regression in PHPUnit 12.

[doppynl]

No need to be sorry, it happens. PHPUnit 12 already found a couple of minor issues in my testcode that are now fixed.

I used coversClass and usesClass for a couple of Enums in PHPUnit 11 without any problems. (not sure about 10, but I guess the same).

I've no problem with changing the configuration to something new/different, but right now it appears it isn't possible to configure coverage for enums at all in PHPUnit 12.

[sebastianbergmann]

Okay, this is a regression then.

[sebastianbergmann]

Should have been fixed by 68403fa. I have released version 12.0.1 of this library with that change.

Confirmed it is now working fine for me.
Thnx!
