Hi there,
Forgive the simple sounding question, but I'm struggling to understand how
to spec helper methods in Rails work, and I'm having no joy, and after
spending far, far too long staring at broken code, I'm hoping someone on the
list can shed some light.
All I'm trying to do is spec how a one line helper method for a view should
behave, but I'm not sure what kind of mock object, (if any) I should be
creating if I'm working in Rails.
Here's the method first - I've used it to try to keep a view free of logic:
module EventsHelper
def filter_check_button_path
params[:filter].blank? ? '/images/buttons/bt_search_for_events.gif' :
'/images/buttons/bt_refine_this_search.gif'
end
end
And here's my spec code:
require File.expand_path(File.dirname(__FILE__) + '/../spec_helper')
describe EventsHelper do
#Delete this example and add some real ones or delete this file
it "should be included in the object returned by #helper" do
included_modules = (class << helper; self; end).send :included_modules
included_modules.should include(EventsHelper)
end
it "should return the 'refine image search' button if a search has been
run" do
# mock up params hash
params = {}
params[:filter] = true
# create an instanc of the class that should include EventsHelper by
default, as the first test has verified (I think)
@event = Event.new
# call method to check output
@event.filter_check_button_path.should
be('/images/buttons/bt_search_for_events.gif')
end
end
When I've looked through the docs here -
http://rspec.info/rails/writing/views.html, I'm mystified as to where the
'template' object comes from.
I've also tried looking here, which I thought would point me in the right
direction, but alas, no dice.

What should I be looking for here in the docs, and what am I doing wrong?
Thanks,
Chris
