Function scoping issue

I have a method called insert_user which is working fine in other parts of the application but for some reason it's undefined in this case and cannot figure out why

** (CompileError) test/models/user_repo_test.exs:8: undefined function insert_user/1
    (stdlib) lists.erl:1338: :lists.foreach/2
    (stdlib) erl_eval.erl:670: :erl_eval.do_apply/6
    (elixir) lib/code.ex:376: Code.require_file/2
    (elixir) lib/kernel/parallel_require.ex:59: anonymous fn/2 in Kernel.ParallelRequire.spawn_requires/5

This is the code:

defmodule Rumbl.UserRepoTest do
  use Rumbl.ModelCase
  alias Rumbl.User

  @valid_attrs %{name: "A User", username: "eva"}

  test "converts unique_constraint on username to error" do
    insert_user(username: "eric")
    attrs = Map.put(@valid_attrs, :username, "eric")
    changeset = User.changeset(%User{}, attrs)

    assert {:error, changeset} = Repo.insert(changeset)
    assert {:username, "has already been taken"} in changeset.errors
  end
end

This is the definition at test/support/test_helpers.ex

defmodule Rumbl.TestHelpers do

  alias Rumbl.Repo

  def insert_user(attrs \\ %{}) do
    changes = Enum.into(attrs, %{
      name: "Some User",
      username: "user#{Base.encode16(:crypto.strong_rand_bytes(8))}",
      password: "supersecret",
    })

    %Rumbl.User{}
    |> Rumbl.User.registration_changeset(changes)
    |> Repo.insert!()
  end

  def insert_video(user, attrs \\ %{}) do
    user
    |> Ecto.build_assoc(:videos, attrs)
    |> Repo.insert!()
  end

If you didn't import Rumbl.TestHelpers in the Rumbl.ModelCase in using macro block, you have to add it explicitly in your test suite to have this functions imported.

It should help, but otherwise - please check that your TestHelpers is placed in test/support directory. In mix.exs you should have a function like this:

defp elixirc_paths(:test), do: ["lib", "web", "test/support"]

So without placing your file in proper directory, it won't be loaded.
