What am I doing wrong with this rspec helper test?

Question

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 code for events_helper.rb: ``` 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, in events_helper_spec.rb: ``` 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 instance of the class that should include EventsHelper b…

Accepted Answer

You are not doing anything in that spec, just setting a stub, so it will pass, but hasn't tested anything.

```
require File.expand_path(File.dirname(__FILE__) + '/../spec_helper')

describe EventsHelper do
 it "should return the 'refine image search' button if a search has been run" do
  # mock up params hash
  params = {:filter => true}

helper.stub!(:params).and_return(params)
  helper.filter_check_button_path.should eql('/images/buttons/bt_search_for_events.gif')
 end
end
```
