I’m writing some tests for my app and sometimes I change the runtime configs for a specific test. To make sure each test runs with the config specified in config/config.exs I’d like to “reset” the config before each test. I’ve tried adding Mix.Config.import_config("config/config.exs) to the ExUnit setup_all callback but apparently this function cannot be called during runtime (** (RuntimeError) could not set configuration via Mix.Config. This usually means you are trying to execute a configuration file directly instead of using the proper command, such as mix loadconfig). Any suggestions?
