Release testing instructions for the WooCommerce Stripe payment gateway 5.6.0

How to test the new payment experience - Universal Payment Element (UPE)

Background

The new payment experience, also known as Universal Payment Element (UPE) provides a new checkout experience, supporting multiple local payment methods in the same UI component. Please read "UPE element" as the new UI checkout component, and "UPE payment methods" as the payment methods supported under this new checkout component.

Test activating UPE enables the correct payment methods.

1. Go to WooCommerce -> Settings -> Payments
2. Note which Stripe payment gateways are enabled.
3. Click Manage next to the main Stripe Gateway.
4. Check Try the new payment experience.
5. Click Save Changes at bottom of the page.
6. When page reloads check that the enabled payments methods at the bottom of the page match the same stripe payment gateways which were enabled before UPE was enabled, except Multibanco and Alipay which are not supported by UPE.
7. Toggle a few payment methods.
8. Disable UPE by un-checking Try the new payment experience.
9. Click Save Changes at bottom of the page.
10. View which gateways are enabled on the main WooCommerce -> Settings -> Payments page. They should match what was enabled in the UPE settings.

Test UPE element reasonably matches current theme

Install and activate several WordPress themes and check:

• CSS rules are read from the theme and passed to the UPE iFrame on the checkout page.
• The selected payment method in the UPE should have the same color as the place order button.
• The text inputs in the UPE element should have the same background and border colors as the rest of the inputs on the page.
