defmodule MvWeb.MemberLive.IndexGroupsIntegrationTest do
  @moduledoc """
  Tests for integration of groups with existing features in the member overview.

  Tests cover:
  - Groups column works with Field Visibility (column can be hidden)
  - Groups filter works with Custom Field filters
  - Groups sorting works with other sortings
  - Groups work with Membership Fee Status filter
  - Groups work with existing search (but not testing search integration itself)
