    ])

    defmodule DemoLive do
      use Phoenix.LiveView

      def mount(_params, _session, socket) do
        {:ok, assign(socket, count: 0)}
      end

      def render(assigns) do
        ~H"""
        <span>Count: <%= @count %></span> <button phx-click="inc">+</button>
        """
      end

      def handle_event("inc", _params, socket) do
        {:noreply, update(socket, :count, &(&1 + 1))}
      end
    end

    Logger.configure(level: :info)
    ExUnit.start()

    defmodule DemoLiveTest do
      use ExUnit.Case
      use PhoenixPlayground.Test, live: DemoLive

      test "it works" do
        {:ok, view, html} = live(build_conn(), "/")

        assert html =~ "Count: 0"
        assert render_click(view, :inc, %{}) =~ "Count: 1"
        assert render_click(view, :inc, %{}) =~ "Count: 2"
      end
    end
