How to test a Burrito-wrapped app?

Questions & Help Questions
1

I was having a hard time running tests and wrapping my tiny app with Burrito so I came up with this strategy, but I wasn’t sure if this is the best way to go about it.

Is there a simpler way to do it?

# config.exs
import Config

config :pled, compile_env: Mix.env()

# application.ex
defmodule Pled.Application do
  use Application

  alias Pled.CLI

  @impl true
  def start(_type, _args) do
    env = Application.get_env(:pled, :compile_env)

    if env == :test do
      children = []
      opts = [strategy: :one_for_one, name: Pled.Supervisor]
      Supervisor.start_link(children, opts)
    else
      Burrito.Util.Args.argv()
      |> CLI.parse_args()
      |> CLI.handle_command()

      System.halt(0)
    end
  end
end

Looks solid to me.

:peer iirc allows testing beam applications even if e.g. wrapped in a docker image. I‘d expect that could also be done to burrito binaries with a bit of setup.
