Release testing instructions for WC Payments 2.6.0

Testing for Customer Multi-Currency Feature

Customer Multi-Currency allows a shop to allow their customers to choose which currency they'd like to use to see and pay for products.

Pre-requisites/Setup:

Set _wcpay_feature_customer_multi_currency option in the wp_options table to 1. Or use the following snippet: update_option( '_wcpay_feature_customer_multi_currency', '1' ); in the Code Snippet plugin.
Once you have the _wcpay_feature_customer_multi_currency option set to 1, you should be able to see a "Multi-Currency" settings tab on the settings page after clicking on Payments > Settings. Make sure this is present, in order to test the scenarios below.

Go to WP Admin and click on the "Multi-Currency" tab on the WooCommerce > Settings page.
On the settings page, click the Add Currencies button. A modal should appear.
Verify that the search box works as expected by searching for a currency and verifying that the currency list updates only the expected currency displays.
Tick the Danish Krone option in the currency list then click Update selected. The UI should update and Danish Krone should now be in the list of enabled currencies.
Click the bin icon to the right of Danish Krone. A modal should appear. Click Remove Currency. Verify that Danish Krone gets removed from the list of enabled currencies.

As an admin:

In WP Admin, click on Appearance > Widgets. Verify you can see "Currency Switcher" in the list of available widgets.
Click on the currency switcher widget and add it to the sidebar of the site. Tick both the Display currency symbols and Display flags options.

As a guest user:

Go to the shop page on the site. Verify the currency switcher appears in the sidebar. Change the selected currency and verify that the page should reload and all items in the shop will now display in the selected currency.
Test toggling the Display currency symbol option and verify the currency symbol no longer displays in the currency switcher list. Do the same with the Display flags option.
Add some items to the cart and go to the cart page, click Pay now and use a Stripe test card: 4242 4242 4242 4242, any cardholder name, valid expiration date and CVV will work.
Order should be completed correctly.

As a logged in user:

Go to the My Account -> Account Details page. Update the "Default currency" option, save changes.
Go to the shop page. Prices should be displayed in your selected currency.
Add some items to the cart and go to the cart page, click Pay now and use a Stripe test card: 4242 4242 4242 4242, any cardholder name, valid expiration date and CVV will work.
Order should be completed correctly.

Add the currency switcher widget to the store as described in scenario 2.
Go to WP Admin and click on the "Multi-Currency" tab on the WooCommerce > Settings page. Make a note of the exchange rates for the EUR, NZD and CDF currencies.
Go to the shop page on the store, switch between USD, EUR, NZD and CDF and verify that the prices all look right (are converted from their USD price at the appropriate rate) and are formatted accordingly:
- USD should look like $xx,xxx.xx
- EUR should look like €xx.xxx.xx
- CDF should look like Frxx,xxx.xx
- NZD should look like $xx,xx.xx
Make sure that discounted prices and variation price ranges are rendered correctly.

Simple Products

Make sure the price is converted in the Shop, Product, Cart and Checkout pages.
Purchase the product and check that the order has the right currency and price
Navigate to the My Account -> Orders page and ensure that the currency used was the selected one.

Variable Products

Make sure the price is converted in the Shop, Product, Cart and Checkout pages.
Modify the selected currency and ensure the price range was updated. It is cached by WooCommerce by default, but should be refreshed when the exchange rate changes.
Purchase the product and check that the order has the right currency and price
Navigate to the My Account -> Orders page and ensure that the currency used was the selected one.

Coupons

Enable coupon codes in the General WooCommerce settings
Create three coupons, one for each type
Ensure that the fixed cart discount and fixed product discount amounts are converted when using them
Ensure that the percentage discount works correctly and the percentage defined in the coupon is applied to the order
Add a minimum and maximum spend usage restriction to a coupon, and check that those values are converted and matched against the cart subtotal

Shipping

Add a free and a flat rate shipping method to your shipping zone
Make sure that they work correctly on the checkout page
If apply_charm_only_to_products is enabled, the shipping rate should only be ceiled after conversion
If it's not, the shipping rate should also have the charm pricing added to it
Set a Minimum order amount for free shipping. Make sure that the minimum order amount is checked against the selected currency. For example:
- If the minimum order amount is set to $100.
- $100 in the cart should give free shipping.
- Change the store currency to GBP.
- The amount needed to qualify for free shipping should now be £71 (because of the conversion rate between USD and GBP).
- Ensure that the order still qualifies for free shipping.

Taxes

Enable taxes in the General WooCommerce settings and create a standard tax rate
Ensure that taxes are correctly applied and converted when using both "Prices inclusive of tax" and "prices exclusive of tax"
Ensure that the shipping methods' taxes are also converted properly under both configurations
