problem asynchronizing ecto calls

It looks like the project is already doing that. The test file starts with

defmodule Project.Module do
    use Project.ModelCase

And in model_case.ex we’ve got

  setup tags do
    :ok = Ecto.Adapters.SQL.Sandbox.checkout(Project.Repo)

    unless tags[:async] do
      Ecto.Adapters.SQL.Sandbox.mode(Project.Repo, {:shared, self()})
    end

    :ok
  end

So since :async isn’t included in the use line I believe that means we’re using shared mode, so any process should be able to connect to the DB connection.
