how can I investigate when a rspec test fails?

rubyonrails-talk
#1

For example:

it "re-renders the 'new' template" do
      # Trigger the behavior that occurs when invalid params are submitted
      Sector.any_instance.stub(:save).and_return(false)
      post :create, :sector => {}
      response.should render_template("new")
end

I have the new template under app/views/sectors but the test says:

SectorsController POST create with invalid params re-renders the 'new' template
     Failure/Error: response.should render_template("new")
     expecting <"new"> but rendering with <"">

#2

Please post the controller action so we can see what's missing.

#3

It sounds like the test is working and that your code is at fault by
the looks of it. Do you have a "render"/redirect_to method being
called in your 'create' controller action? Where is it going?

#4

I'm using inherited_resources so in my controller I don't have any
action defined.
The controller is simply:

class SectorsController < InheritedResources::Base

  def destroy
    destroy!(:notice => t('Sector')+" deleted.")
    rescue
      flash[:error] = t('Sector')+" is not deleted."
  end
end

#5

If I launch the application and I try to create an invalid sector, it
renders the new template correctly
I have another application and this test:

it "re-renders the 'new' template" do
     UnsafeBuilding.stub(:new) { mock_unsafe_building(:save => false) }
     post :create, :unsafe_building => {}
     response.should render_template("new")
end

This works and the controller uses inherited_resources too.
I don't understand why the test in the first application doens't work
while the one in the second application works.
