@DisplayName("It is not possible to add a dog that already has a different owner")
public void addingDogAlreadyOwnedByOtherOwner() {
var dog = newDog();
var owner = newOwner();
var otherOwner = newOwner("Otherowner");

otherOwner.addDog(dog);
var rv = owner.addDog(dog);

assertDogsOwned(false, rv, owner);
}
@Test
@Order(140)
@DisplayName("It is not possible to remove a dog that has a different owner when you do not own any dogs")
public void removingDogOwnedByOtherOwnerWhenOwningNoDogs() {
var dog = newDog();
var owner = newOwner();

otherOwner.addDog(dog);
var rv = owner.addDog(dog);

assertDogsOwned(false, rv, owner);
}
