From Ruby to Elixir: test send_sms_message/1 missing configuration in test.exs
Page 178 describing the test send_sms_message/1. We are missing to mention that the test.exs should import the dev secrets
import_config "./dev.secret.exs"
If not we get into the error:
test/phone_app/conversations/conversations_test.exs:8
** (KeyError) key :number not found in: []
Which comes from not getting any value on (lib/phone_app/conversations/conversations.ex)
def your_number do
twilio_config = Application.get_env(:phone_app, :twilio, [])
Keyword.fetch!(twilio_config, :number)
end
First Post!

I believe this is on page 149, but it would be very easy to miss.
edit: see next comment, this is referring to dev and not test.
