我们正在尝试将我们的 CI 从 Travis 移植到 Heroku。测试在本地和 Travis 上都通过了，但是在 Heroku 上，我们遇到了一些难以调试的 erlang 错误。

所有错误似乎都来自于在模拟AWS S3 请求时使用 Elixir Mock模块的测试。

这是一个示例测试：

  test "put_object failure function" do
    with_mock ExAws, [request!: fn(_) -> %{status_code: 500} end] do
      res = S3.put_object("unique.png", "binary")
      assert res == {:error, "error uploading to S3"}
    end
  end

而 put 对象很简单：

  def put_object(unique, image_binary) do
    bucket = System.get_env("BUCKET_NAME")

    res = ExAws.S3.put_object(bucket, unique, image_binary)
    |> ExAws.request!

    case res do
      %{status_code: 200} ->
        {:ok, image_url(unique, bucket)}
      _ ->
        {:error, "error uploading to S3"}
    end
  end

所以我不太确定出了什么问题。

Heroku CI 的错误在这里：

      8) test put_object failure function (Engine.S3Test)
         test/controllers/s3_test.exs:34

将模拟版本更新为 0.3.1 -{:mock, "~> 0.3.1", only: :test}
