I’m getting a function undefined error that totally mystifies me: describe "sessions" do alias Koko.Authentication.Session @valid_user_attrs %{"admin" => true, "blurb" => "BLURB!", "email" => "yada@foo.io", "name" => "Yada T. Urdik", "username" => "yada", "password" => "abc.617.ioj"}…

Alright. I am not entirely sure the reason behind it, but it turns out you cannot call the function in the describe/2 block, but you can call it in the test/1 block. I am not really sure of the limitations on this because I was able to call List.first/1 without an issue. So maybe it is limited to fu…

If you move the function definition outside of the describe/2 block, it will be available. You may want to check the documentation for describe/2 , specifically the section on hierarchies, it may fit your needs. I think there is probably a debate on whether or not what you are trying to do should be…

I tried that – same error. I have two describe blocks. They both need to use user_fixture. I moved that definition out of the first block, deleted the definition of user_fixture2, and now have two calls to ``user_fixture`: on in the first describe block, the other in the second. The error comes …

Do you have a repository with a small example to show this behaviour? Because after doing a small test, defining the function in the describe/2 block works as expected.

You could also try using an anonymous function instead of a named one.

I have koko_dev and koko_test repositories. The tests should be addressing the former – it is empty.

I’m sorry, I meant a git repository or something. Somewhere we can take a look at the code.

Yes, I just pushed the branch I am working on: https://github.com/jxxcarlson/koko/blob/login/apps/koko/test/koko/authentication/authentication_test.exs#L83

You can’t call functions from within the module body that defines them.

So being within the describe/2 block is considered inside of the module body, but being inside the test/1 block does not?

Yup. You can tell because it lets you set module attributes in the describe block, which you can’t do inside of a function.
