Hi,
rspec version: 2.4.0
Given this helper - snippet:
----
def participants_summary table
table.participants.collect{|participant|
show_short_participant_link(participant) }.join(', ')
end
def show_table_link(table)
link_to(table.name, :action => :show, :id => table)
end
---
and this spec
---
describe 'participants_summary' do
let(:table) { new_table :participants => [
new_participant(:id=> 1, :name =>
'name1'),
new_participant(:id=> 2, :name =>
'name2') ] }
it "includes the names of all participants" do
participants = participants_summary table
participants.should
include(link_to('name1', :controller=>'person',:action=>'show',:id=>1))
participants.should
include(link_to('name2', :controller=>'person',:action=>'show',:id=>2))
end
end
---
The spec passes, but the real output is escaped.
the helper should look like this
----
def participants_summary table
raw table.participants.collect{|participant|
show_short_participant_link(participant) }.join(', ')
end
---
I think (but i am not sure) that rspec should mimic Rails' behaviour
in escaping all html from such helpers unless you put 'raw' in front.
I can fix this in my case doing:
render :text => participants_summary(table)
rendered.should include(link_to('name1', :controller=.......etc
This actually appears to use the rails3 rendering engine, or at least
it fails if i remove the 'raw' call.
Sadly, theconsequence of this is inserting something like this for not
all but quite a few helpers.
Does anybody know of another way of dealing with this. Do you think
that this render => :text call should be (an implicitly or explicit)
part of the HelperExampleGroup?
I have put it in like this in one of my spec/support -ing files
module HelperRenderer
# renders the text as view so that rails view rendering magic
# (like implicit HTML escaping) can take place
def render_helper(text)
render :text => text
rendered
end
end
module RSpec::Rails::HelperExampleGroup
include HelperRenderer
end
