how to test onSuccess callback provided by useSWR

[yashpandit]

I have been using the onSuccess callback frequently to manage things that should happen once I get a response from the server and sometimes it has complicated logic that should be unit tested.

However, I have not been able to come up with a good strategy to unit test the onSuccess callback. I have a wrapper hook around useSWR that handles some biz logic and a mock that serves very well for testing/mocking server responses. Has anyone else faced this issue or has a strategy they can share here?

I am using Jest with RTL. Appreciate any help. Thanks!
