Controller Test with Pow

Fixed. Had to recycle the conn manually.

test "redirects to show when data is valid", %{authed_conn: conn} do
      conn = post(conn, Routes.product_path(conn, :create), product: @create_attrs)
      assert %{id: id} = redirected_params(conn)
      assert redirected_to(conn) == Routes.product_path(conn, :show, id)

      conn = recycle_conn(conn) <-- Added

      conn = get(conn, Routes.product_path(conn, :show, id))
      assert html_response(conn, 200) =~ "Show Product"
    end

defp recycle_conn(conn) do
    saved_assigns = conn.assigns
    conn =
      conn
      |> recycle()
      |> Map.put(:assigns, saved_assigns)
    conn
  end

All the tests are passing now, but i have defined the recycle_conn function on the controller_test, what if i want to test another authed controller? Need to redefine again, or create another helper module and define it there to ease reuse.
Im pretty new to elixir/phoenix and web dev in general. Sorry for my english

Hi, After adding Pow, I has 9 test failing, after placing the setup macro to add the user to the conn i has 3 tests that keep failing with error.

** (RuntimeError) expected response with status 200, got: 302, with body:
“You are being <a href="/session/new?request_path=%2Fadmin%2Fproducts%2F150">redirected.”

If i remove :protected from pipeline on the scope all test pass. So it has to be something with the authentication. Thanks

Yeah, you would only ever need to do that if you are testing the session controller itself. Assigning :current_user is sufficient for all other controllers/routes.

If I am reading this thread right, there’s no point to have a test that does a POST and validates that Pow successfully authenticates a user then?

Your second example is the way to go. This could also be done in a setup macro like so:

    setup %{conn: conn} do
      user = %Golf.Accounts.User{email: "test@example.com", id: 1}
      authed_conn = Pow.Plug.assign_current_user(conn, user, [])

      {:ok, conn: conn, authed_conn: authed_conn}
    end

    test "redirects to show when data is valid", %{authed_conn: authed_conn} do
      conn = post(authed_conn, Routes.course_path(authed_conn, :create), course: @create_attrs)

      assert %{id: id} = redirected_params(conn)
      assert redirected_to(conn) == Routes.course_path(conn, :show, id)

      conn = get(authed_conn, Routes.course_path(authed_conn, :show, id))
      assert html_response(conn, 200) =~ "Show Course"
    end

It’s because of how phoenix recycles connections in tests. The response conn will have a :state key set to :sent so when it’s reused the test helpers in Phoenix will build a new connection and only copy over headers e.g. cookies. Assigns will not be preserved.
