Testing our app is pretty easy. You'll just have to place a test order after going through the onboarding/settings setup.
Test in-checkout validation
Add a product to your cart and go to checkout
Enter an address without a house number (e.g. "Musterstraße, 12345 Berlin")
If in-checkout validation is active, you'll see an error message blocking the purchase
Test post-checkout validation
Add a product to your cart and go to checkout
Enter an address with a deliberate error – e.g. a non-existent house number or a misspelled street
Complete the purchase
On the Thank You page, you should see an AddressHero popup prompting you to review and correct the address
✅ Tip: Use a Shopify development store or a test payment method (e.g. Bogus Gateway) to test without creating real orders.
