@kinglozzer I am getting
Indirect modification of overloaded property SilverCommerce\TaxAdmin\Tests\Model\TestProduct::$extension_instances has no effect
That’s weird… I don’t know what might be overloading it 😬
Can you post some code?
Ah, the event hook itself is added by an extension, that might cause issues
Basically I want to test this extension hook: https://github.com/silvercommerce/tax-admin/blob/1.0/src/extensions/PricingExtension.php#L191
