Rails - Jan 2006 - scaffold code fails functional test?

I have the following scaffold generated code which does not run. It does not
even hit the breakpoint.

  def create
    breakpoint()
    @student = Student.new(params[:student])
    if @student.save
      flash[:notice] = ''Student was successfully created.''
      redirect_to :action => ''list''
    else
      render :action => ''new''
    end
  end

 I decided to run functional test on the controller. Here is the result:

  1) Failure:
test_create(StudentControllerTest)
[test/functional/student_controller_test.rb:55]:
Expected response to be a <:redirect>, but was <200>

Also from another action I get the following error:

  2) Failure:
test_edit(StudentControllerTest)
[test/functional/student_controller_test.rb:68]:
<false> is not true.

I don''t undertand why this code fails and what the failure means.

Can someone also please explain when to use redirect_to vs. render? Thanks
for your help.
