Any idea how i could make phpunit start correctly ? Thanks

You appear to have a project-local version of PHPUnit installed using Composer but instead of invoking that (using ./vendor/bin/phpunit) you invoke another version of PHPUnit (using phpunit, for instance).

Thanks a lot, but if i use this version

../../../vendor/bin/phpunit -c multisite.xml

I still get a fatal error

Fatal error: Class PHPUnit_Util_Test may not inherit from final class (PHPUnit\Util\Test) in /private/var/folders/j3/t3yfbrhd6q3f__6dhfcmxnjc0000gn/T/wordpress-tests-lib/includes/phpunit6-compat.php on line 18

What should i do, remove the phpunit installed via composer and use the one delivered with MAMP ?
