ruby on rails - Why is this Factory causing a test to fail, when building the record manually passes? -

in rails app i'm testing user confirmations

scenario "unconfirmed user cannot login"   user = create(:user, confirmation_sent_at: 10.days.ago ) #factorygirl factory   login user   expect(current_path).to eq(#unconfirmed_user_path) end 

this fails, , user signed in.

however if change first line follows

user = create(:user) user.confirmation_sent_at = 10.days.ago user.save login user ..... 

the test passes.

what overlooking? these 2 pieces of code equivalent aren't they?
