Integration test for the order for a query in Rails 5

Rails 5 will deprecat assigns, which is handy when testing the order of an AR query.

test "admin sorts members by date joined" do
  get memberships_path(sort: :by_date_joined)
  memberships = assigns(:memberships)
  assert_equal [@bart, @lisa, @homer], memberships.to_a
end

Integration tests in Rails 5 encourage you to simulate the user experience as much as possible. This means we should search the rendered HTML for the right links.

[@bart, @lisa, @homer].each do |member|
  assert_select "#member_#{member.id}"
end

assert_select is useful if we want to ensure that members are being rendered correctly, but it does not guarantee order.

So what can we do to test the order?
