PHPUnit does nothing Gitlab-ci

When Gitlab-ci execute the script : php vendor/phpunit/phpunit --colors --verbose --configuration phpunit.xml

PHPUnit seems to do nothing this is the output from Gitlabci :

$ php vendor/phpunit/phpunit --colors --verbose --configuration phpunit.xml
Job succeeded

I've tried with no option for PHPUnit and it's still the same i don't understand why, it's working properly on my local

I'm working with the framework Laravel
