Hello I am trying to test my liveview and I want to test the editing of a resource through liveview. So I have something like this:
{:ok, view, _html} = live(conn, ~p"/my_resource/#{id}/edit")
params = %{some_key: "some value"}
{:ok, view, html} =
view
|> form("#my-form")
|> render_change(params)
|> render_submit()
|> follow_redirect(conn, ~p"/my_redirect_route")
My problem is that the return type of render_change is not what render submit is expecting and it errors out on the render_submit() line. This is the error I get:
** (FunctionClauseError) no function clause matching in Phoenix.LiveViewTest.render_event/4
The following arguments were given to Phoenix.LiveViewTest.render_event/4:
# 1
"<div>my html string</div>"
# 2
:submit
# 3
%{}
# 4
%{}
I have tried using the element/3 function and splitting this out into 2 steps but that failed also. Is there a way I can render some changes and then submit the form? I am sure there is I am just missing something… Thanks!

Makes total sense! That worked. Thanks!
