   -----------------       ---------------       -------------------------
   PHPUnit 8                PHP 7.2 / 7.3         "phpunit/phpunit": "^8"
   PHPUnit 7                PHP 7.1               "phpunit/phpunit": "^7"
   PHPUnit 6                PHP 7.0               "phpunit/phpunit": "^6"
   PHPUnit 5                PHP 5.6               "phpunit/phpunit": "^5"
