Pull Request Overview

This PR attempts a major version upgrade of PHPUnit from 9.5.28 to 13.1.14. This transition introduces significant breaking changes that are not addressed in the current diff. Specifically, PHPUnit 10 introduced a total rewrite of the event system and a required XML schema migration for phpunit.xml, while PHPUnit 11+ requires PHP 8.2 or higher.

Since this PR only modifies the dependency version without updating the test suite's configuration or refactoring legacy test cases (e.g., migrating DocBlock annotations to PHP attributes), the test suite is guaranteed to fail in its current state. These architectural gaps must be resolved before this PR can be considered for merging.

About this PR

• The PR performs a major version jump from PHPUnit 9 to 13. PHPUnit 10 introduced massive breaking changes, including a complete rewrite of the event system, the removal of several legacy TestCase methods (like at()), and the migration of metadata from DocBlock annotations to PHP attributes. The absence of changes to existing test files or configuration files in this PR suggests that the test suite will likely fail upon merging.

Test suggestions

• Verify that all existing tests pass using PHPUnit 13's runner.
• Verify that the phpunit.xml configuration file is migrated to the schema required for PHPUnit 10 and above.

Prompt proposal for missing tests

Consider implementing these tests if applicable:
1. Verify that all existing tests pass using PHPUnit 13's runner.
2. Verify that the `phpunit.xml` configuration file is migrated to the schema required for PHPUnit 10 and above.

_{🔴 HIGH RISK}

Bumping PHPUnit from version 9 to 13 introduces significant breaking changes. The phpunit.xml configuration file requires a schema migration for PHPUnit 10+, and the minimum PHP version requirement has increased (PHPUnit 11 requires PHP 8.2+). Without these updates, the test suite will fail. You should update phpunit.xml to the latest schema and verify that the environment meets the new PHP version requirements.
