[keycloak-dev] Integration test: Verify url that was used in an adapter backchannel request

[Luca Graf]

I currently work on KEYCLOAK-6073 (Support different URLs for front and
back channel requests in adapters) and try to implement some kind of
integration test, to verify that an adapter actual use its configured
url for backchannel requests.

When I understand the existing integration tests correct, it should be
relative easy to trigger most of the actions that execute backchannel
requests
(code-to-token, logout, etc.) with an adapter test
(AbstractExampleAdapterTest, AbstractServletsAdapterTest). But I don't
see a straight forward way how to verify the url that was actual used by
the adapter (in the deployed example or servlet).

Not sure if I am on the right track, so any thoughts on how to approach
this are appreciated. :)

Thanks
Luca
