provided fails to match with multiple test facts

[smpallen99]

I have a short example with test facts. Both facts pass by themselves (one or the other is commented out), but fail when both are present. Here is the output:

➜  mock git:(master) ✗ mix test
Elixir.MockTest
  sends a syncro message
  sends by cabinet
Failures:
  1) test sends by cabinet (MockTest)
     ** (Amrita.MockError) Expected:
     Mdse.HbManager.send_udp(nil,nil,32780,1) to be called but was called 0 times.
       Actuals calls:
         * Mdse.HbManager.send_udp(nil,nil,32780,1)
     stacktrace:
       lib/amrita/message.ex:16: Amrita.Message.mock_fail/1
       test/mock_test.exs:6: MockTest."test sends by cabinet"/1
Finished in 0.1 seconds (0.07s on load, 0.05s on tests)
2 facts, 1 failures

Here is my test code: mock_test.ex

Code.require_file "../test_helper.exs", __ENV__.file
defmodule MockTest do
  use Amrita.Sweet
  it "sends by cabinet" do
    provided [Mdse.HbManager.send_udp(nil, nil, 32780, 1) |> true] do
      Mdse.HbManager.send(nil, 32780, 1) |> :ok
    end
  end
  it "sends a syncro message" do
    msg = <<1::32, 2::32, 3::32, 0::32, 6::32>>
    provided [Mdse.HbManager.send_udp(_, {}, 0, _) |> true] do
      Mdse.HbManager.handle_info({:udp, 0, {}, 0, msg}, nil) |> {:noreply, nil}
    end
  end
end

And the source...

supervisor.ex

defmodule Mock.Supervisor do
  use Supervisor.Behaviour
  def start_link do
    :supervisor.start_link(__MODULE__, [])
  end
  def init([]) do
    children = [ worker(Mdse.HbManager, []) ]
    supervise(children, strategy: :one_for_one)
  end
end

hb_manager.ex

defmodule Mdse.HbManager do
  use GenServer.Behaviour
  def start_link() do
    :gen_server.start_link({ :local, :HbManager }, __MODULE__, 0, [])
  end
  def send(ip_or_cabinet, port, message) do
    :gen_server.cast :HbManager, {:send, ip_or_cabinet, port, message }
  end
  def init(_) do
    {:ok, nil}
  end
  def handle_cast({:send, ip, port, message}, state) do
    Mdse.HbManager.send_udp state , ip, port, message
    {:noreply, state}
  end
  def handle_info({:udp, _sock, ip, port, message}, state) do
    Mdse.HbManager.send_udp(state, ip, port, message)
    {:noreply, state}
  end
  ###########
  # Helpers
  def send_udp(sock, ip, port, message) do
    IO.puts "send_udp #{inspect sock} #{inspect ip}:#{port} - #{inspect message}"
    #:gen_udp.send sock, ip, port, message
  end
end

Thanks for the detailed report, I'll investigate.

[smpallen99]

Any update on this issue? If you do not have time to investigate, perhaps you can point out a few things I can investigate myself. This is blocking me from any mocked testing in my application.

Thanks, Steve

@smpallen99 I'll take a look to day and at least have some guidance as to the problem if I cannot fix it in the time I have.

Thanks
