PHP Unit 5.5.x / 4.8.x Code-Coverage not working

Hello together,

I established some problems while trying to use code coverage in PHPStorm 2016.02.

The tests got executed, coverage-files are created, CodeCoverage-Data window shows up.. but then there is no coverage shown (0%) and no lines getting colored...

OS: OS X El Capitan 10.11.6

PHP Version: 7.0.8

XDebug: 2.4.0

PHP Unit: 5.5.5 / 4.8  

phpunit.xml:

<?xml version="1.0" encoding="UTF-8"?>
<phpunit>
    <filter>
        <whitelist>
            <directory suffix=".php">src</directory>
        </whitelist>
    </filter>
</phpunit>

PHPUnit Output:

/usr/local/opt/php70/bin/php -dxdebug.coverage_enable=1 /Applications/XAMPP/htdocs/projekte/deltatecc-intern/ArticleCategoryMapper/vendor/phpunit/phpunit/phpunit --coverage-clover /Users/deltatecc/Library/Caches/PhpStorm2016.2/coverage/ArticleCategoryMapper$ArticleCategoryMapperTest_testGetCategory.coverage --configuration /Applications/XAMPP/htdocs/projekte/deltatecc-intern/ArticleCategoryMapper/phpunit.xml --filter "/::testGetCategory( .*)?$/" deltatecc\ArticleCategoryMapper\ArticleCategoryMapperTest /Applications/XAMPP/htdocs/projekte/deltatecc-intern/ArticleCategoryMapper/tests/src/ArticleCategoryMapperTest.php --teamcity
