How to use ExVCR with Finch?

[danicuki]

My project uses Finch to make parallel HTTP requests.

I tried to add VCR to my tests, but the HTTP requests are still happening.

Here is my test:

defmodule MyClientTest do
  use ExUnit.Case, async: true
  use ExVCR.Mock #, adapter: ExVCR.Adapter.Httpc

  setup do
    ExVCR.Config.cassette_library_dir("fixture/vcr_cassettes")
    :ok
  end

  test "list_apps" do
    use_cassette "list_apps" do
      list_apps = MyClient.list_apps
      assert MyClient.list_apps == ["app1", "app2"]
    end
  end

end

I see a list_apps.json file in the fixture/vcr_cassettes, but its content is only []

Here is my MyClient module:

defmodule MyClient do
  alias Finch.Response

  def child_spec do
    {Finch,
     name: __MODULE__,
     pools: %{
       "https://myapp.com" => [size: 100]
     }}
  end

  def applications_response do
    :get
    |> Finch.build("https://myapp.com/v2/apps.json")
    |> Finch.request(__MODULE__)
  end

  def handle_applications_response({:ok, %Response{body: body}}) do
    body
    |> Jason.decode!()
    end
  end

  def list_apps do
    handle_applications_response(applications_response())
  end

end

How to apply VCR to this example?

I believe this issue can now be closed since Finch support is there and documented in the README.

I'm using this with Finch as documented and haven't had any issues. This can be closed.
