A minimal PHPUnit suite covers pure-logic parts of the plugin (status mapping, API response validation) without booting a Shopware kernel. It uses its own standalone dev dependencies under tests/vendor (see tests/composer.json), independent of the plugin's own composer.json and of the parent Shopware project, so running it never requires shopware/core/shopware/storefront to be installed.

Setup (once):

cd tests && composer install

Run the tests (from the plugin root):

php tests/vendor/bin/phpunit

tests/vendor and .phpunit.cache are git-ignored and are not part of the release zip built by pack.sh.
