Testing

Maru.Test only works with designated Maru.Router, so if you want to test a router named API, you should use Maru.Test like this:

Ruby

defmodule API do
  use Maru.Router

  get do
    text(conn, "hello")
  end
end

defmodule APITest do
  use Maru.Test, for: API

  test "/" do
    assert "hello" = get("/") |> text_response
  end
end

Test router include multiple versions

Ruby

defmodule API do
  use Maru.Router

  version "v1" do
    get do
      text(conn, "hello")
    end	
  end
  
  version "v2" do
    get do
      json(conn, %{hello: :world}
    end	
  end
end

defmodule APITest do
  use Maru.Test, for: API

  test "/ v1" do
    assert "hello" = get("/", "v1") |> text_response
  end

  test "/ v2" do
    assert %{"hello" => "world"} = get("/", "v2") |> json_response
  end
end

Test router with headers or params

Ruby

defmodule API do
  use Maru.Router

  params do
    requires :foo
  end
  post :path do
    ...
  end
end

defmodule APITest do
  use ExUnit.Case
  use Maru.Test, for: API

  setup do
    conn = 
      build_conn()
      |> put_req_header("content-type", "application/json")
      |> put_plug(Plug.Parsers, parsers: [:json], pass: ["*/*"], json_decoder: Poison)
    {:ok, %{conn: conn}}
  end
  
  test "/", %{conn: conn} do
    assert %Plug.Conn{} = conn |> put_body_or_params(~s({"foo":"bar"})) |> post("/path")
  end
end
