Undefined method `flunk'

[mschuerig]

Rails 3.0.0, rspec-rails 2.0.0.beta20, ruby 1.8.7

I can't include the original code, unfortunately. The exception occurs in a controller spec. The controller correctly redirects_to :back and the spec looks like this

describe Admin::FooBarsController do
  before do
    @bar = mock_bar
    request.env["HTTP_REFERER"] = '/somewhere'
  end

  describe "PUT update" do
    before do
      Bar.should_receive(:find).with('42').and_return(@bar)
    end
    it "redirects back" do
      response.should redirect_to('http://test.host/somewhere')
    end
  end
end


Failures:
  1) Admin::FooBarsController when signed in as an authorized user PUT update with foo bars redirects back
     Failure/Error: response.should redirect_to('http://test.host/somewhere')

Please take a look at this issue: http://github.com/rspec/rspec-rails/issues/issue/182

[mschuerig]

This is apparently the same problem, however, I don't think the solution is to not accept string URL in should redirect_to checks. As #182 is already closed, I'm leaving this one open.

[justinko]

All should redirect_to does is delegate to the Rails assert_redirect_to method. flunk is a Test::Unit method and it was not being defined (or delegated) in RSpec, hence the error. You can see the Rails method here: http://github.com/rails/rails/blob/master/actionpack/lib/action_dispatch/testing/assertions/response.rb#L62

You can pass a URL string to should redirect_to.

Try `response.location.should eq("http://test.host/somewhere")' to spec it directly.

Duplicate of #182, which was closed after the beta.20 release and will be part of the beta.21 release

[deschaefer]

Will the use case:

response.should redirect_to(:controller => "messages" , :action => "new" )

Result:

undefined method `flunk' for #RSpec::Core::ExampleGroup::Nested_4::Nested_2:0x00000102c395a8

Also be resolved in beta.21?

Thanks,
Don

[dchelimsky]

Yes, undefined method 'flunk' is resolved by 2ddb07

[gotoAndBliss]

Is there a way to temporarily resolve this until .21.beta comes out?

I apologize ahead of time, if that sounds daft :D

[dchelimsky]

Make this method available to your specs as a workaround:

def flunk(*args, &block)
  assertion_delegate.flunk(*args, &block)
end
