if i have a channel test like given below, is it possible to assert that socketA client received a particular event and socketB received a particular event ?

defmodule RockPaperScissorsWeb.GameChannelTest do
  use RockPaperScissorsWeb.ChannelCase

  test "players get correct results" do

    player_id_a = UUID.uuid4()
    player_id_b = UUID.uuid4()
    game_channel_id = UUID.uuid4()

    {_, _, socketA} = joinGameChannel(game_channel_id, player_id_a)
    {_, _, socketB} = joinGameChannel(game_channel_id, player_id_b)

    push(socketA, "move", %{"player_id" => player_id_a, "move" => "r"})
    push(socketB, "move", %{"player_id" => player_id_b, "move" => "r"})

   # assert that socketA client received a particular event
   # assert that socketB client received a particular event
  end


  # Helpers
  defp joinGameChannel(game_channel_id, player_id) do
    RockPaperScissorsWeb.Socket
    |> socket(nil, %{})
    |> subscribe_and_join(
      RockPaperScissorsWeb.GameChannel,
      "game:#{game_channel_id}",
      %{"player_id" => player_id}
    )
  end

end
