[keycloak-dev] Testing with mocking libraries?

[Anil Saldanha]

You really have to test your core logic (with no server set up) using
integration tests with mocking libraries. One way to test out all the
possible preconditions to your logic.

You will be doing a service to your customers and users by shielding them
from those nasty exceptions (NPEs) that happen in an integration platform
such as KeyCloak/RH-SSO. :-)
