If there is an completely empty file with only one line without a trailing linebreak in your coverage folder, the coverage can't be created, because the value for $linesOfCode after counting \n is 0, whereas the calculated amount of comments is 1 and results in an exception of type SebastianBergmann\LinesOfCode\NegativeValueException.
Fatal error: Uncaught SebastianBergmann\LinesOfCode\NegativeValueException: $nonCommentLinesOfCode must not be negative in /.../vendor/phpunit/phpunit/src/TextUI/Command.php on line 103
