You can enable the test gateway and test your store checkout view and purchase transactions in your WooCommerce store. To enable test payments, go to FunnelKit Settings ⇨ One Click Upsells. Enable the Test Gateway By FunnelKit from there. Then test purchase an item from your store by going to the checkout flow and selecting Test Gateway by FunnelKit on the checkout page. This allows you to test your checkout process by completing a test transaction in your WooCommerce store.
