[laurentmuller]

I'm using this greate tool for everydays. Thank You !

I will now update phpunit to version 11.0.

But this plugin require the nikic/php-parser 5.0 instead of version 4.0.

I'ts possible to merge this 2 versions in the composer.json file like as follow:

"require": {

    "nikic/php-parser": "^4.0 || ^5.0"
