 **Current setup:**
 PHP version 8.2.15
 WordPress version 6.4.3
 PHPUnit version 11.0.3

 **Issue:**
 Trying to get unit testing for plugin development running but there is a
 call to a deprecated/no-longer present method the following file:

  /tmp/wordpress-tests-lib/includes/abstract-testcase.php


 {{{
 Error: Call to undefined method
 PHPUnit\Util\Test::parseTestMethodAnnotations()

 /tmp/wordpress-tests-lib/includes/abstract-testcase.php:546
 /tmp/wordpress-tests-lib/includes/abstract-testcase.php:137
 /var/www/html/wp-content/plugins/solomons-services/vendor/yoast/phpunit-
 polyfills/src/TestCases/TestCasePHPUnitGte8.php:60
 }}}


 **What I discovered**
 Strictly this a breaking change in the PHPUnit codebase implied by the
 class annotation:

  ''@internal This class is not covered by the backward compatibility
 promise for PHPUnit''.

 The method
 [https://github.com/sebastianbergmann/phpunit/blob/9.6.16/src/Util/Test.php#L334
 parseTestMethodAnnotations() was present upto and including 9.6.16] of
 PHPUnit however the file underwent a massive change and it's
 [https://github.com/sebastianbergmann/phpunit/blob/10.0.0/src/Util/Test.php
 not been present since 10.0.0].


 **Workaround**
 Comment out the call to PHPUnit\Util\Test::parseTestMethodAnnotations() in
 abstact-testcase.php and the tests will run with a deprecation warning
 related to metadata and annotations but that doesn't affect this issue. I
 don't at this stage know if there's any other side effects as a result of
 this workaround.
