You can test your WooCommerce checkout before going live by enabling Test Mode in the Ziina payment settings.
How to enable Test Mode:
Log in to your WordPress dashboard
Go to WooCommerce → Settings
Click on the Payments tab
Select Ziina
Enable the option called Test Mode
Click Save Changes
Once Test Mode is enabled, you can simulate payments on your website.

Important:
Test transactions do not charge the customer’s card
No real money is processed
Test payments will not reflect in your balance
Before launching your website, make sure to disable Test Mode so you can start accepting real payments.
