When configuring API Policies in the the Oracle API Platform it helps if there is a simple back end that can take the received payload and record the sent values (header & body) as well as reflect the call details back as the response, or possibly respond with a test payload (so that response policies, particularly policies that require payload navigation can be exercised correctly). By having this facility it becomes a lot easier to determine whether the policies are executing correctly in terms of routing, transforming, filtering etc. without needing to worry about whether the API implementation is correct. You could say that this is a kind of mock for testing the API Platform.
The added benefit of having a mock back end is that it is easy to ‘smoke test’ a gateway deployment very easily. Particularly if the mock is happy to receive any form of call.
