Testing a conditional validation with remarkable

Question

I have a rails model with this validation:

  validates_numericality_of(:insert_oz,
                            :allow_blank=>true,
                            :greater_than=>0,
                            :if=>(proc do |note|
                                    !note.insert_pages.nil? &&
                                       note.insert_pages > 0
                                  end))

Using remarkable, how do I test a validation that uses the :if option?

If I do the obvious, and add the validation to my spec, changing "validates" to "should_validate":

  should_validate_numericality_of(:insert_oz,
                                  :allow_blank=>true,
                                  :greater_than=>0,
                                  :if=>(proc do |note|
                                          !note.insert_pages.nil? &&
                                            note.insert_pages > 0
                                        end))

Then the spec fails with this message:

'Processingnote should ensure numericality of insert oz is greater than 0 and allowing blank values' FAILED
Expected Processingnote to be invalid when insert oz is less than 1

try and catch statements?
