I'm trying to test a method on the application controller that will be used as a before filter. To do this I have setup an anonymous controller in my test with the before filter applied to ensure that it functions correctly.
The 开发者_如何学JAVAtest currently looks like this:
describe ApplicationController do
controller do
before_filter :authenticated
def index
end
end
describe "user authenticated" do
let(:session_id){"session_id"}
let(:user){OpenStruct.new(:email => "pythonandchips@gmail.com", :name => "Colin Gemmell")}
before do
request.cookies[:session_id] = session_id
UserSession.stub!(:find).with(session_id).and_return(user)
get :index
end
it { should assign_to(:user){user} }
end
end
And the application controller is like this:
class ApplicationController < ActionController::Base
protect_from_forgery
def authenticated
@user = nil
end
end
My problem is when ever I run the test I'm getting the following error
1) ApplicationController user authenticated
Failure/Error: get :index
ActionView::MissingTemplate:
Missing template stub_resources/index with {:handlers=>[:erb, :rjs, :builder, :rhtml, :rxml, :haml], :formats=>[:html], :locale=>[:en, :en]} in view paths "#<RSpec::Rails::ViewRendering::PathSetDelegatorResolver:0x984f310>"
According to the docs the view is not rendered when running controller tests however this points to no stub existing for this action (which is understandable as the view doesn't exist)
Anyone have a clue how to solve this problem or stub the view out.

Couldn't you get round this by putting:
render :nothing => true
inside the #index
action?
A better way to do this is to create a dummy views directory. I wouldn't use spec/views, as that is actually for valid view tests. Instead, create this directory structure:
spec/test_views/anonymous
index.html.erb
... and any other anonymous controller templates you happen to need ...
index.html.erb can be empty, as noted, since rspec2 is only checking for existence, not for content.
Then in your application.rb initializer, place this line:
# add a view directory for the anonymous controller tests
config.paths['app/views'] << "spec/test_views" if Rails.env.test?
Note: I tried putting that line in test.rb, for some reason doesn't seem to work there.
Unless things changed from this blog post, RSpec 2 needs a view template file for controller specs to work. The file itself is not rendered (unless you add render_views
), so the contents don't matter -- in fact you can simply add an empty file with touch index.html.erb
.
If you are looking at this for Rails 5+, putting head :ok
in the index action is the right answer, as indicated by marc_ferna in a comment under another answer.
e.g.
controller do
before_filter :authenticated
def index
head :ok
end
end
