DrupalPractice_Project::getInfoFile() assumes there is a file; won't work with piping code to PHPCS

        $pathParts = pathinfo($phpcsFile->getFilename());

        // Search for an info file.
        $dir = $pathParts['dirname'];

This assumes that the $phpcsFile object has a filename to work with. This is not necessarily the case if you're running a string through a pipe to the phpcs command, or calling the PHPCS code directly with a string.
