That doesn't actually work like it did in 1.x, because the rails internals have
changed:
it "renders the edit gadget form" do
view.should_receive(:render).with(:partial => "_form")
render
end
$ rspec spec/views/gadgets/edit.html.erb_spec.rb
F
1) gadgets/edit.html.erb renders the edit gadget form
Failure/Error: render
#<ActionView::Base:0x103696f28> received :render with unexpected arguments
expected: ({:partial=>"_form"})
got: ({:template=>"gadgets/edit.html.erb"}, {})
You have to say this instead:
it "renders the edit gadget form" do
view.should_receive(:_render_partial).with(hash_including(:partial =>
"form"))
render
end
... which is a bit of a kludge and subject to changes in rails' internals.
That's why I want to use "render_template", which delegates to
"assert_template", which is a rails API and less likely to break.
Make sense?
