I have simple test case:

it "is removed when associated board is deleted" do
  link = FactoryGirl.create(:link)
  link.board.destroy
  expect(Link.find(link.id)).to raise_error ActiveRecord::RecordNotFound
end

And it fails with output: 

1) Link is removed when associated board is deleted
   Failure/Error: expect(Link.find(link.id)).to raise_error ActiveRecord::RecordNotFound
   ActiveRecord::RecordNotFound:
     Couldn't find Link with id=1
   # ./spec/models/link_spec.rb:47:in `block (2 levels) in <top (required)>'

Any idea why ?
