Coverage ask me to cover uses?

[steevanb]

Q	A
php-code-coverage version	10.1.1
PHP version	8.2.5
Driver	PCOV / Xdebug (same behavior)
PCOV version (if used)	1.0.11
XDebug version (if used)	3.2.1
Installation Method	Composer
Usage Method	PHPUnit
PHPUnit version (if used)	10.1.2

When i execute code coverage with PHPUnit 10.1, i have a lower covered percent than i have with exactly the same code but PHPUnit 9.5.

After some research, i've found PHPUnit 9.5 do not found files who contains only an Enum, but PHPUnit 10 found them, so i have to add coverage on my methods in Enum. That's ok.

The problem is with another difference: PHPUnit 10.1 ask me to cover "some" uses (not for all files, and i don't understand why?)

I've tried with pcov and xdebug, same behavior.

My command to execute PHPUnit (exaclty same command for PHPUnit 9.5 and 10.1):

php \
    bin/ci/phpunit.php \
        --configuration "${ROOT_PATH}"/config/ci/phpunit.xml \
        "${ROOT_PATH}"/tests

bin/ci/phpunit.php:

#!/usr/bin/env php
<?php

declare(strict_types=1);

if (ini_get('date.timezone') === false) {
    ini_set('date.timezone', 'UTC');
}

define('PHPUNIT_COMPOSER_INSTALL', dirname(__DIR__, 2) . '/vendor/autoload.php');
require PHPUNIT_COMPOSER_INSTALL;
exit((new \PHPUnit\TextUI\Application())->run($GLOBALS['argv']));

config/ci/phpunit.xml (for PHPUnit 10.1):

<?xml version="1.0" encoding="UTF-8"?>
<!-- https://phpunit.readthedocs.io/en/latest/configuration.html -->
<phpunit
