Change class namespace rises coupling between objects violation

[astronom]

• PHPMD version: 2.12.0
• PHP Version: 8.0.18
• Installation type: composer
• Operating System: Docker container php:8.0.17-fpm-alpine3.15

Current Behavior

Before changes. SomeHandlerTest has coupling between objects - 12 (13 is the max default value)

namespace App\Tests\functional\Action\Handler\SomeHandler;

use ....;
use App\Tests\functional\ApiTestCase;

final class SomeHandlerTest extends ApiTestCase
{
.... some code here
}

PHPMD reports that there is no violations

Then we want to replace namespace App\Tests\functional to App\Tests\Functional

After changes. No other code changed

namespace App\Tests\Functional\Action\Handler\SomeHandler;

use ....;
use App\Tests\Functional\ApiTestCase;

final class SomeHandlerTest extends ApiTestCase
{
.... some code here
}

PHPMD reports:

FILE: /var/www/html/tests/functional/Action/Handler/Player/PersonalBonus/SomeHandlerTest.php
----------------------------------------------------------------------------------------------------------
 24 | VIOLATION | The class CheckPersonalBonusHandlerTest has a coupling between objects value of 14. Consider to reduce the number of dependencies under 13.
