rspec users - Dec 2010 - my helper stubs aren't working (rspec2, rails3)

My helper tests broke when I upgraded to rails3/rspec2.  I don''t seem
to
be able to stub out methods in my helper tests.

Anyone know what''s going on here?

#users_helper_spec.rb
describe UsersHelper do
  describe "the helper" do
    it "should stub" do
      helper.stub(:foobar_method).and_return(666)
      helper.foobar_method.should == 666
    end
  end
end

gives me:

 1) UsersHelper the helper should stub
  Failure/Error: helper.foobar_method.should == 666
  undefined method `foobar_method'' for
#<ActionView::Base:0x4808014>
  # ./spec/helpers/users_helper_spec.rb:5

I copied that code into a new Rails 3/RSpec 2 app and the example passes without
error.

Can you post your Gemfile and spec/spec_helper.rb files? I''m guessing
there''s a configuration problem of some sort.

Cheers,

You only need ^^ rspec-rails here. It requires rspec, which requires
rspec-mocks. I''d actually recommend using this format:

  gem "rspec-rails", "~> 2.3"

This will accept updates up to, but not including 3.0. This means
you''ll get bug fixes and/or new functionality, but no breaking
changes.

Unfortunately, I don''t see anything here right out of the gate that
would be causing this.

Would you try bootstrapping a new app and see if the same thing happens?

<script>
gem install rails bundler
rails new example
cd example
echo ''gem "rspec-rails", "~> 2.3", :group =>
[:development, :test]'' >> Gemfile
bundle install
rails generate rspec:install
rails generate scaffold Things name:string
echo ''require "spec_helper"

describe ThingsHelper do
  it "supports stubs" do
    helper.stub(:foo) { "bar" }
    helper.foo.should eq("bar")
  end
end
'' > spec/helpers/things_helper_spec.rb
rake db:migrate && rake db:test:prepare
rspec spec/helpers/things_helper_spec.rb -cfd
</script>

When I run this I get the following output:

<output>
ThingsHelper
  supports stubs

Finished in 0.0257 seconds
1 example, 0 failures
</output>

Unfortunately that worked:

   ThingsHelper
     supports stubs

. . . so there''s something weird going on with my app.

Any other suggestions before I start wrestling with it?

It''s New Year''s Day. Start with a pint, and then go from there
:)

It seems that I left out a critical detail :)

I was using incorrect syntax to stub a different method in a before
block:

  before do
    stub(:some_other_method).and_return(val)
  end

Which appears to silently break stubbing.  Try the following:

  describe ThingsHelper do
    it "supports stubs" do
      stub!(:bar) {"foobar"}
      helper.stub(:foo) { "bar" }
      helper.foo.should eq("bar")
    end
  end


that gives me:

  1) ThingsHelper supports stubs
     Failure/Error: helper.foo.should eq("bar")
     undefined method `foo'' for #<ActionView::Base:0x1cef47c>
