2. On the Home screen select Setup WooCommerce Payments task to trigger KYC flow.
3. After KYC flow completion you should be redirected to the setup payment methods task screen.
4. Go to Payments > Settings page to confirm the account is created and its status displayed.
5. Before starting tests, double check the currency is set correctly for each country. If not, go to WooCommerce > Settings > General and change the currency.
6. Go to Payments > Settings page, and make sure all these payment methods are displayed for each country: Card payments, iDEAL, Bancontact, EPS, P24, Giropay, and SEPA.
7. Turn these payment methods on by selecting the checkbox near each method. Scroll down and click Save.
8. Open the store and add a product to the cart. Go to checkout and make sure all selected methods from the step before are showing in the payment form.
9. Pay for your order using a test card like 4242424242424242.
10. Once the order is completed, go to Payments > Transactions screen in WP Admin and make sure the transaction is showing correctly.
11. Back to the store, and add a new product to your cart.
12. Pay for the order via a payment method other than a card (iDEAL, SEPA... Pick one for each country, no need to test all of them)
13. Once the order is completed, go to Payments > Transactions screen in WP Admin and make sure the transaction is showing correctly.
14. Note: For Norway only, you might see incorrect amounts displayed, that's a known bug that will be fixed in another version of WooCommerce Core.
15. Now, back to the store, add a product to the cart, and head to the checkout screen. Now pay using the card 4000000000000259 to trigger a dispute.
16. Navigate to Payments > Disputes in WP Admin and make sure the dispute is showing correctly.
17. That's it. This process can be repeated for another country now.
