Hi there! I’m having an issue when running MIX_ENV=test mix test. To my knowledge it should use the test.exs file which I have hardcoded values for, but when I run my tests I notice its using runtime.exs instead - is there a way to force it to use the test.exs or am I missing something? Let me know if I can provide more information

First off, you don’t need to specify MIX_ENV=test when you run
mix testunless you’re overwriting otherwise present environemnt variable of that name.Secondly, it’s expected behavior.
runtime.exsis executed at tuntime in all environments.If you want to limit the execution of
runtime.exsin anything but prod, you can add an if clause to it like this:The above would only execute the contents of the script in
