error with feature case: ** (MatchError) no match of right hand side value: {:already, :allowed}

[hoangbits]

I want to put use Wallaby.Feature inside a FeatureCase (similar role to ConnCase),
But then when I use it in a test module with: use AppWeb.FeatureCase, async: true
at: https://github.com/hoangbits/wallaby-bug-report1/blob/c5bbfd2cf5f0f683a934685ffb06b95893aae329/test/app_web/integration/index_test.exs#L2
I got the error.

Detail stacktrace:

➜ mix test test/app_web/integration

I really appreciate any help.

You don't need any of the stuff in the setup block of your ExUnit case template, as wallaby takes care of that for you when you do use Wallaby.Feature

[hoangbits]

So I remove use Wallaby.Feature from CaseTemplate and bring it use Wallaby.Feature to test module.
inside test module:

defmodule AppWeb.Integration.IndexTest do
  use AppWeb.FeatureCase, async: true
  use Wallaby.Feature

But the same error was still raised as long as I keep async: true like above.

[mhanberg]

I am saying to remove the setup block, not the call to use Wallaby.Feature.

When you do use Wallaby.Feature, it will automatically checkout the ecto repo as well as start a session.

You are getting your original error because you are checking out the repo a second time.

You are getting your original error because you are checking out the repo a second time.

it's clear to me now.
Thank you very much.
