Test instructions

Howdy,

What's your recommendation for getting started testing this package? I had to manually change config/config.exs and use System.get_env("NAME") instead of {:system, "NAME"}. Is that the expected approach or am I missing something?

Hey @rupurt what error were you getting when running tests? I just realized that if System variables were not used then this package would throw error (ArgumentError) non-alphabet digit found: "_" because of an issue with decoding the api secret. I supplied a fix here #8 and tried to make the different environment configurations more explicit.

I use System.get_env("NAME") instead of {:system, "NAME"}, but either approach should work. Let me know if #8 fixes the issue or if you get another error when running tests.

Hey @bnhansn,

I was getting the same error because {:system, "NAME"} wasn't reading anything in for me. I'm pretty new to Elixir so I'm not really sure why. Once I changed it to System.get_env("NAME") it worked fine.

Fwiw I have a .env file for each environment e.g. .env.test, .env.production, .env.development and source the file for the environment I need.

I don't usually use .env files with elixir so I haven't tested that here, I set the values in my ~/.bash_profile. Anyways since System.get_env is working, I'll close the issue, but anyone is free to open it if the {:system, "xxx"} approach is not working and can provide more information. Thanks.

@bnhansn so after reading the code in https://github.com/bnhansn/ex_gdax/blob/master/lib/ex_gdax/config.ex I understand what is happening. I thought {:system, "GDAX_API_KEY"} was a special way to read environment variables but "GDAX_API_KEY" is just literally the key, LOL!!
