Sto facendo delle prove con i test.

fixture:

reservation1:  
user: admin  
room: stanza1  
moderator\_password: “prova”  
attendee\_password: “prova”  
reserved\_from: “2012-11-06”  
reserved\_to: “2012-11-12”

test:

class ReservationTest \< ActiveSupport::TestCase  
test “Reservation attributes must not be empty” do  
reservation = Reservation.new  
assert reservation.invalid?  
assert reservation.errors[:moderator\_password].any?  
end

test “Reservation do not overlap date” do  
reservation1 = Reservation.new  
assert reservation1.errors[:moderator\_password].any?  
end

quello che non capisco e’ perche’ mi da un failure nel secondo test.  
E’ uguale al primo, se il primo passa dovrebbe passare anche il secondo.

Non uguale. Nel primo chiami invalid?, che implementato chiamando  
!valid?  
Il metodo valid? prima di restituire il risultato esegue le validazioni  
quindi popola errors.

Nel secondo caso errors vuoto perch non hai eseguito le validazioni.

Accidenti … una svista, scusate.
