Quick poll. Should a server under test be configured with

application.conf

from the

main

sourceset if the config in the

test

sourceset is absent?

👌

Yes and no. for tests, it is rather important to be able to override the properties dynamically. Because if we speak of testing in the context of a web framework, it most likely means that we are talking about integration tests. And today people use containers to boot the external dependencies for such testing, e.g. Testcontainers. Hence, even if the test app can configure itself with application.conf it is not enough - it should be possible to override the individual properties depending on the conditions when the test is already running

So your point is that a

test

config should override properties in

main

config?

no-no-no. I think it wouldn’t be a great idea. picking up config from main if it’s not present in test is ok. but it should be possible to override the individual properties in the test code itself, doesn’t matter from where the config is loaded
