Empty string checkbox value considered invalid during test

[davydog187]

Environment

• Elixir version (elixir -v): 1.16.2
• Phoenix version (mix deps): 1.7.11
• Phoenix LiveView version (mix deps): 0.20.11
• Operating system: MacOS Sonoma
• Browsers you attempted to reproduce this bug on (the more the merrier): N/A
• Does the problem persist after removing "assets/node_modules" and trying again? Yes/no: N/A

Actual behavior

I have a form defined like so. The underlying data type is an array of Ecto.Enum

    field :products, {:array, Ecto.Enum}, values: @products, default: []

The form looks like this

<.form for={@products_form} phx-change="change_products" id="products-form">
  <.input
    type="checkbox"
    name="organization[products][access]"
    value={Enum.member?(@products_form[:products].value, :access)}
    label="Access"
  />
  <.input
    type="checkbox"
    name="organization[products][reporting]"
    value={Enum.member?(@products_form[:products].value, :reporting)}
    label="Reporting"
  />
</.form>

When we get the params during change events, the checked boxes from the page load will come back as empty strings like so

products #=> %{"access" => "", "reporting" => "false"}

When writing a LiveView test, this is treated as an invalid value for a checkbox

     ** (ArgumentError) value for checkbox "organization[products][access]" must be one of ["false", "true"], got: ""
     code: |> render_change()
     stacktrace:
       (phoenix_live_view 0.20.11) lib/phoenix_live_view/test/live_view_test.ex:1102: Phoenix.LiveViewTest.call/2
       test/myapp_web/live/page_live_test.exs:260: (test)

Expected behavior

I see that this is either a problem with the Javascript or the correct set of possible values in test. So the expected behavior is either:

1. Checkboxes always return "true" or "false" as values during change events
2. Empty string "" is a valid checkbox value during tests

This was an (admittedly confusing) user error, closing
