You can probably have a configuration option via application:get_env/2 you
can use to make the discrimination. On the top of my head, this is what I
would do.

Advice: don't do it. Keep your test artifact equivalent to the deployment
artifact. Make the application such that normal configuration parameters
can be set in order to make the application work in the test environment.
It is safer in the long run because you don't want too many diverging code
paths based on the environment it lives in. It is simply too brittle, and
that would be my advice.
