[rspec-users] stubbing helper methods for View specs

Hi there

I have several view specs, that include the following snippet in  
their "before" block to stub the methods by acts_as_authenticated

   before :each do
     @u = mock_model(User)
     @u.should_receive(:name).and_return("Hans Muster")
     template.should_receive(:logged_in?).and_return(true)
     template.should_receive(:current_user).and_return(@u)
   end

this works for views / helpers like this:

   it "should show bla" do
     render "/layouts/thetool"
     response.should have_tag("p", "bla")
   end

and the view (haml to make things more interesting)

   - if logged_in?
     %p bla


Now I also use Ezra acl_system2 plugin which defines a "restrict_to"  
method that queries some roles. When I stub the methods above and run  
specs, I get the following error:

ActionView::TemplateError in ''/users/show should display the  
information of the user''
undefined local variable or method `current_user'' for  
#<Spec::Rails::DSL::ViewExampleController:0x35d5cc0>

     57:         = role.title

     60:   = link_to "Bearbeiten", edit_user_url(@user)

     ...



Interestingly, when I misspell the name of the stub in the working  
example, I get the following error:

1)
ActionView::TemplateError in ''/shared/layout_test not logged in  
should have the correct head information''
undefined method `logged_in?'' for #<ActionView::Base:0x22ec6f8>

     vendor/plugins/rspec_on_rails/lib/spec/rails/dsl/behaviour/ 
view.rb:51:in `render''
     spec/views/layouts/thetool_haml_spec.rb:16


Note the different class (#<ActionView::Base:0x22ec6f8> vs  
#<Spec::Rails::DSL::ViewExampleController:0x35d5cc0>) in the two specs.

I don''t have enough rspec_fu to deduce where the problem lies..


Any helpers?

thanks

In a nutshell - Rails compiles templates the first time they are
encountered in a given runtime. Combine this with the fact that mock
expectations are cleared out after every example, but the mock
framework doesn''t have access to the compiled template, and you can
imagine that this is )(*&)(*ing nightmare-ish can of worms.

I thought I had a solution for this in trunk, but I''ve just discovered
some problems with it and am working to resolve them.

Sorry - can''t be more helpful right now.

so my best bet would be to use regular functional tests for the time  
being? (Having no specs/tests kind of seems to be the wrong solution  
to this problem...

Agreed that you shouldn''t be without examples for this stuff, but you
have other options within rspec:

1 - use rspec controller examples in integration mode and use real
objects (almost exactly like rails functionals, except its rspec).

2 - use rspec view examples without mocking things directly on the
template. You can still mock helper methods (on controller or
helpers).
