When I run the test with 13.2 I get

RuntimeException: testInvalidVersionNumber registered its own error handler without restoring the previous one before or during tear down. This can cause unpredictable test results. Ensure the test cleans up after itself.

13.2 won't work with Drupal: PHPUnit 13.2 breaks Drupal's approach for ignoring deprecations #6705.

You need to bump to 13.3-dev (which the MR in the parent issue does, but that one also includes the change here, so do not expect a test failure with it). The issue here is occurring from 13.2, nevertheless.

Per #5 the easiest way to test this is to clone the MR from #3574681: [Nov 2026] Introduce support for PHPUnit 13.5, install the updated dependencies, then run the test:
phpunit core/tests/Drupal/Tests/Core/Extension/ExtensionVersionTest.php --filter testInvalidVersionNumber
The test will pass. Check out the test file to get it back to a failing state:
git checkout main -- core/tests/Drupal/Tests/Core/Extension/ExtensionVersionTest.php
Then run the test again. It will fail with the error specified by the issue summary:

The data provider specified ... is invalid
The key must not be an empty string

The fix in this MR is the same as that from #3574681. Because the test passes with this fix in place, it looks good to me. I didn't note any problems with the few code changes introduced.
