Hello

I create a graphql API according to the book “Craft graphql apis in elixir with absinthe”.

When I create tests, I run into an error:

  1) test Category field returns category items (BiidiWeb.Schema.Query.CategoryTest)
 test/biidi_web/schema/query/category_test.ex:15
 ** (RuntimeError) expected ExUnit callback in BiidiWeb.Schema.Query.CategoryTest to return :ok | keyword | map, got %Biidi.Category{__meta

__: #Ecto.Schema.Metadata<:loaded, “categories”>, id: 4, inserted_at: ~N[2018-09-18 20:19:16.469878], title: “other”, updated_at: ~N[2018-09-18
20:19:16.469890]} instead
stacktrace:
(ex_unit) lib/ex_unit/callbacks.ex:368: ExUnit.Callbacks.raise_merge_failed!/2

I searched in Google and in the Forum, but cause I’m new in Elixir and Phoenix I don’t get a propper understanding of the occurring issue.

Here is a working dockerized copy reduced to the failing part:
https://gitlab.com/birdnestman/biidi_test

You can run docker-compose, create DB, migration and then run the test…

Thank you for any help!

Got it. The error appears in the “setup do”

I forgot to add
“:ok”
to the end of the seeds file…

Sorry im new to doing test cases, can anyone share with me how do you seed data for specific test case?

e.g.

  describe "files" do
    alias Myproject.Documents.File
    import Myproject.DocumentsFixtures

    @invalid_attrs %{title: nil, tmp_file_id: nil}

    # QUESTION: What is the proper way to do this and i have a seeder script to run it in other environments
    setup do
      status = [
        %{id: 1, title: "Queueing"},
        %{id: 2, title: "Processing"},
        %{id: 3, title: "Error"},
        %{id: 4, title: "Completed"}
      ]

      for %{id: sid} = s <- status do
        case Repo.get(Status, sid) do
          nil -> struct(Status, s) |> Repo.insert!(on_conflict: :nothing)
          es -> es |> Status.changeset(s) |> Repo.update!(on_conflict: :nothing)
        end
      end

      %{file: file_fixture()}
    end

    test "list_files/0 returns all files", %{file: file} do
      assert Documents.list_files() == [file]
    end

    # ...

Thanks in advance!!!

Best wishes,

If you only need it for that particular test, i suggest to use a fixture too for the states.

If you want to use different seeds in general, have a look at this post: How to seed database for testing? - #3 by ThrashAbaddon
