In rspec-2/rails-3, view.should render_template("event_list") is no longer a
message expectation (pre-action), but rather delegates to Rails'
assert_template method, so it needs to come _after_ the action. It should work
exactly as you have it above, just after the action.
This is documented in the rspec-rails README
(https://github.com/rspec/rspec-rails - see sections on View Specs and
Matchers), though not with an upgrade note pointing out that it changed. I'll
make that addition shortly.
As for stubbing the template, so that it is not actually rendered, RSpec
doesn't offer a way to do this in view specs and I don't think Rails does
either. I added an issue for this
(https://github.com/rspec/rspec-rails/issues/issue/263), and hopefully we'll be
able to resolve it soon. In the mean time, the examples will need to supply any
data needed by the template being spec'd _and_ any of the partials.
Side note: I urge you not to put message expectations (pre "When") or
state-based expectations (post "When") in before/after blocks. It makes
examples difficult to understand, and results in specifying the same things in
every example in a group. Rather, have one example that specifies each
individual thing. In this case:
it "renders the event_list with @calendar" do
render
view.should render_template(
"event_list",
:locals => {:calendar => @calendar}
)
end
