Testing forms

I’m testing a view that renders a form to edit an object. I’d like to
test that the form correctly populates the form with the object’s
attributes’ current values. I tried several variations on mock_model
and stub_model in order to maintain view/model separation–for instance:

require “spec_helper”

describe “informational_widget_frameworks/edit.html.erb” do
describe “rendered items” do
before(:each) do
@iwf = mock_model(InformationalWidgetFramework,
:heading => “IWF Heading”,
).as_null_object
assign(:informational_widget_framework, @iwf)
render
end

it "should show 'IWF Heading'" do
  rendered.should include("IWF Heading")
end

end
end

However, when the view is rendered, the value for the text_field bound
to @informational_widget_framework.heading is populated with
“InformationalWidgetFramework_1025”. I’ve tried changing the example
to:

it “should show ‘IWF Heading’” do
@iwf.should_receive(:heading).and_return(“IWF Heading”)
rendered.should include(“IWF Heading”)
end

But, this gives the same results. Using stub_model similarly doesn’t
populate the form fields with anything at all. The only way I can get
these examples to pass is by using the following for my before block:

before(:each) do
@iwf = InformationalWidgetFramework.create(
:heading => “IWF Heading”,
)

assign(:informational_widget_framework, @iwf)
render
end

I’m clearly missing something here…can someone clue me in?

Thanks.

What is the view using to render this field? Also, what versions? There
was an as_null_object + rails 3 bug in beta.20 that got fixed in
beta.22.
