Dummy Payment 
Do not use this code for production but you can use it as a starting point for new payment integrations.
What is the DummyPayment for:
- it brings a simple state machine
- it shows how to integrate payment into the system
- it shows how to handle refunds
- it allows to test checkout process in several ways
State Machine
The module comes with a simple state machine which has a couple of states, commands and conditions. With that state machine it’s possible to trigger events for order items from Zed’s order detail page.
Integration
A couple of examples which shows how a payment is integrated into the system. These examples show:
- how to integrate forms into Yves checkout
- how to add PaymentMethodHandler
- how to add a state machine, commands and conditions to the Oms module
- how to add CheckoutPlugins to the Payment module
- how to handle refunds with the Refund module
Refunds
Refunds mostly triggered by a state machine command, this module shows how that could look like. Look into the RefundPlugin. This command can be triggered from Zed’s order detail page when a order item has the state returned.
Test Checkout
You can do an order as you already used to it. A way to test what happens when something after saveOrder() goes into the wrong direction has been added. A good example for this is when authorizing a payment fails.
When “Invalid” is used as last name the order is saved but all items go into invalid state and the user is redirected to the PaymentStep of Checkout.
