🧪 Add tests for Clientes_model::add

[cezargf]

🎯 What: Added tests for the Clientes_model::add() function, which lacked tests for returning the correct insert_id and handling DB errors.
📊 Coverage: Covered 3 scenarios: Success (returns insert ID), Failure due to zero affected rows (returns false), Failure due to database error (returns false).
✨ Result: Increased code coverage by adding unit tests that properly isolate and verify CodeIgniter's database interactions for this model method. Tests can be run via ./application/vendor/bin/phpunit --bootstrap application/tests/bootstrap.php application/tests/models/ClientesModelTest.php.

Code Review

This pull request introduces unit testing infrastructure by adding a bootstrap file, unit tests for the Clientes_model, and including PHPUnit in the development dependencies. Feedback includes addressing a PHP version conflict in composer.json where the platform version is lower than the required version, and updating a mock expectation in the ClientesModelTest to verify the table argument passed to the insert_id method.

[gemini-code-assist]

The platform PHP version 8.3.6 conflicts with the requirement ^8.4 specified in the require section of this file. This will cause Composer to fail during dependency resolution because the platform version does not satisfy the minimum required version. Please ensure the platform version is at least 8.4.0 or update the requirement to ^8.3 if the project is intended to support PHP 8.3.

[gemini-code-assist]

The mock expectation for insert_id should verify that it is called with the $table argument, as the Clientes_model::add method passes this argument when calling $this->db->insert_id($table).

            ->method('insert_id')
            ->with($table)
            ->willReturn($expectedInsertId);
