Hi,
I’m trying to test my config settings.
To do that, i use a module that load them: like this
defmodule App.SettingsBehaviour do
@moduledoc """
Define the behavior for accessing environment variable settings
"""
@callback is_search_enabled :: boolean
end
defmodule App.BoundSettings do
@options Application.get_env(:app, :options, App.Settings)
def is_search_enabled do
@options.is_search_enabled
end
end
defmodule App.Settings do
@behaviour App.SettingsBehaviour
@impl App.SettingsBehaviour
def is_search_enabled, do: Application.get_env(:app, :search_enabled, false)
end
config/test.exs
config :app, :options, App.OptionsMock
config :app, search_enabled: true
I have a liveview controller calling App.Settings, and when i try to mock it it returns UnexpectedCallError. Does anyone understand what could fail here?
Where Next?

it seems that you have 2 implementations of the module
App.Settings, one doesn’t define the behaviourApp.SettingsBehaviour. one might be overwriting the other.also, are you defining the mock in your test_helper.exs file?

Sorry, the module name copy was a typo of my part. I corrected it.
Yes i am defining the mocks in supports/mocks.ex!!

how is your config for
search_enabledin the test config filenewelixiruser
I updated my post with the config/test.exs content

App.Settingsdoesn’t call any function, just get a value from your Application config store.App.BoundSettingsdoesn’t implement the behaviour.UnexpectedCallErrorusually means that you’re calling the the mock module without setting any expectation on it.given the context you provided, code paths that use
AppBoundSettingsdoesn’t have a expectation onApp.OptionsMock.newelixiruser
One of the expectation was missing making load of tests fails
