Hi there,
I'm still trying to wrap my head around when to use a stub and a mock.
If I understand this right, I should be using a 'mock' when imitating
an object, but not its behavior. I should be using a stub when I want
to imitate the behavior of an object. Does that sound about right?
With that said, I'm struggling a little trying to spec out this
instance method that is available to a User object. The method takes
an OrderPaymentInfo object and copies its attributes onto the User's
attributes (Ignore the clunky design... that's just how it has to be).
The User's instance method looks like so:
class User
def update_billing_info(billing_info)
unless self.has_billing_address?
self.bill_to_address1 = billing_info.address1
self.bill_to_address2 = billing_info.address2
self.bill_to_address3 = billing_info.address3
self.bill_to_city = billing_info.city
self.bill_to_country_code = billing_info.country_code
self.bill_to_state_province_code = billing_info.state_province_code
self.bill_to_postal_code = billing_info.postal_code
self.bill_to_phone_number = billing_info.phone_number
self.bill_to_extension = billing_info.extension
self.bill_to_fax = billing_info.fax_number
self.save ? true : false
else
true
end
end
Here's the spec:
describe User, "when checking billing information" do
before(:each) do
@user = User.new(:id => 1)
@order_payment_info = mock_model(OrderPaymentInfo,
:id => 1,
:user_id => @user.id,
:address1 => "555 Rd.",
:address2 => "Ste 2",
:address3 => "line 3",
:city => "Chicago",
:country_code => "USA",
:state_province_code => "IL",
:psotal_code => "12345",
:phone_number => "5551234321",
:extension => "123",
:fax_number => "5551234321")
@user.stub!(:update_billing_info).with(@order_payment_info)
end
it "should update billing information when User's billing info is nil" do
@user.should_receive(:update_billing_info).with(@order_payment_info)
@user.update_billing_info(@order_payment_info)
@user.stub!(:has_billing_address?).and_return(false)
@user.bill_to_address1.should eql("555 Rd.")
@user.bill_to_address2.should eql("Ste 2")
end
end
When I run this spec I get an "error" of:
1)
'User when checking billing information should update billing
information when User's billing info is nil' FAILED
expected "555 Rd.", got nil (using .eql?)
I'm just wondering what the best way to approach this would be.
Thank you,
Dave Hoefler
