adds the option to provide a custom phpunit command via args

[jayhof]

This feature extends the php-unit hook to allow a custom command for the php-unit tests. This is useful if you want to use https://github.com/fiunchinho/phpunit-randomizer or if you have a more complicated php configuration running as a docker-container.

To illustrate, here's short excerpt from a composer.json

"scripts": {
  "docker-run": "docker run --rm -v $PWD:/var/www dockerimage:latest",
  "php-unit": "@composer run docker-run -- ./var/www/vendor/bin/phpunit-randomizer -c /var/www/phpunit.xml --order rand",
  "test": "@composer run php-unit"
}

By running composer run test the scripts will start a docker-container and run the unit tests on it instead on your local php installation.

To configure the hook you would use:

id: php-unit
args: ["composer run php-unit"]
