Testing Cells

[Harun Pathan]

Hi,

I am using cells 3.3.9 in rails2.3.14 application.

I wanted to test cells with using view_assigns[:symb], but getting an error

ArgumentError: wrong number of arguments (2 for 1)

    .bundle/ruby/1.8/gems/cells-3.3.9/lib/cells/cell/test_case.rb:83:in `render_state'

    .bundle/ruby/1.8/gems/cells-3.3.9/lib/cells/cell/test_case.rb:83:in `render_cell'

    .bundle/ruby/1.8/gems/cells-3.3.9/lib/cells/cell/test_case.rb:93:in `extract_state_ivars_for'

    .bundle/ruby/1.8/gems/cells-3.3.9/lib/cells/cell/test_case.rb:82:in `render_cell'

    test/cells/blog_post_cell_test.rb:11:in `__bind_1320421186_77782'

    .bundle/ruby/1.8/gems/shoulda-2.11.3/lib/shoulda/context.rb:382:in `call'

    .bundle/ruby/1.8/gems/shoulda-2.11.3/lib/shoulda/context.rb:382:in `test: show should return first published blog post. '

    .bundle/ruby/1.8/gems/activesupport-2.3.14/lib/active_support/testing/setup_and_teardown.rb:62:in `__send__'

    .bundle/ruby/1.8/gems/activesupport-2.3.14/lib/active_support/testing/setup_and_teardown.rb:62:in `run'

My testcase:

class BlogPostCellTest < Cell::TestCase

  context "show" do

    should "return first published blog post" do

      war = Factory.create(:blog_post, :title => "War", :is_live => 0)

      peace = Factory.create(:blog_post, :title => "Peace", :is_live => 1)

      category = Factory.create(:blog_category, :title => "War&Peace", :blog_posts => [war, peace])

      render_cell :blog_post, :show, :category => category.title

      assert_equal category, view_assigns[:blog_category]

      assert_equal peace, view_assigns[:post]

    end

end

After investigations, found test_case.rb has 

      def render_cell(name, state, *args)

        @subject_cell = ::Cell::Base.create_cell_for(@controller, name, *args)

        @view_assigns = extract_state_ivars_for(@subject_cell) do

          @last_invoke = @subject_cell.render_state(state, *args)

        end

        @last_invoke

      end

Whereas base.rb has

      def render_state(state)

         ---

      end

If we change @last_invoke = @subject_cell.render_state(state, *args) to @last_invoke = @subject_cell.render_state(state),

it works. 

This looks like a defect.

thoughts?

This case is happening only for cells with options.
