Pull Request Overview

This PR modernizes test data providers in the database test suite by making them static methods and adding explicit array return type declarations. This aligns with PHPUnit's best practices where data providers should be static to avoid unnecessary object instantiation before the test execution.

Key Changes:

• Data provider methods changed from public function to public static function
• Added : array return type declarations to all data provider methods
• Updated internal references from $this-> to self::/static:: where methods became static
