The file attribute of <testClass> node of XML test list can be wrong

[mondrake]

Q	A
PHPUnit version	10.5.38
PHP version	8.3
Installation Method	Composer

Summary

ListTestsAsXmlCommand builds the file attribute of each <testClass> node by getting the file path of the first test case method found in a class, and using the file path returned by calling $test->valueObjectForEvents()->file().

This is not accurate as this returns the file path of the file where the method is defined, not the file path of the class. The method could be defined in a parent base class, or in a trait, and then the file returned would not be the one where the TestCase class is contained.

Current behavior

See above.

How to reproduce

Make an abstract base TestCase class with test case methods in it, a separate concrete class with no methods extending the abstract, and run phpunit with the --list-tests-xml option. The file attribute of the concrete <testClass> will point to the abstract class file and not to the concrete one.

Expected behavior

The file path should match the class, as the autoloader will map.

Thank you for your report.

Please provide a minimal, self-contained, reproducing test case that shows the problem you are reporting.

Without such a minimal, self-contained, reproducing test case I will not be able to investigate this issue.

#6101 contains test changes to prove the bug. It targets 11.5, where this is visible in the XML output file. However, the underlying bug, that IMHO is the lack of a method to retrieve the file where the TestCase class is defined, goes down to 10.5 at least.
