hello how do people replace keys in the system-map during tests? for instance there is system-map with

{::config {}
 ::db {:config (ig/ref ::config)}}

You could use merge, or the meta-merge package to replace keys before ig/init

I assume I also should change all ig/ref to use different keyword?

You shouldn't have to do that, as long as the contents of those keys change before ig/init

You don’t have to. If you want separate behaviour, you can use two different keys that derive from the same parent.

e.g. ::prod-config and ::test-config might derive from ::config

assuming you need a different ig/init-key method.

and I should not require ::prod-config namespace, otherwise wrong init-key might be used?

No, the method is chosen based on the key name. So a init-key for ::prod-config will only work for ::prod-config.

{::test-config {}
 ::db {:config (ig/ref ::config)}}

Ambiguous key: 

You have to make sure that only one of ::test-config and ::prod-config is in your config map.

Otherwise (ig/ref ::config) doesn’t know which one you mean.

oh, found the issue works, thank you!
