I already add xdebug.coverage_enable = On in my php.ini file so I don't understand why the system say that :/
Maybe someone can help me ? Thank you a lot for help me !

Xdebug v3.0.0RC1
PHPUnit 7.5.20
Either upgrade PHPUnit to the version that knows about Xdebug 3 ... or downgrade Xdebug to 2.x (2.9.8 is the latest).
Thing is: xdebug.coverage_enable is the Xdebug 2 option. That option does nothing in Xdebug 3 where you should use xdebug.mode = coverage instead.
Xdebug 3 uses different config options than v2 and your version of PHPUnit is simply not aware of that. Xdebug 3 will simply report an empty value/0 for no-longer-used Xdebug 2 options.
https://3.xdebug.org/docs/upgrade_guide#Changed-Configuration-Settings
P.S. You should see a warning when you run php -i with Xdebug 3 -- it should complain if such a wrong/outdated option is present in your php.ini (unless you have configured PHP to not to report any startup errors I guess).
In either case: run php -i and see the actual live values from Xdebug section: what value that option has.
