I just use a factory method.
describe 'Authorize.net CIM gateway', :shared => true do
describe 'saving a card' do
describe 'preconditions' do
it "should raise an error if the card is not saved" do
lambda {
gateway.save_credit_card(Factory.build(:credit_card, :user =>
Factory(:user)))
}.should raise_error(ArgumentError, /unsaved record/)
end
end
describe 'first card saved on an account' do
it "should set the authorize_id on the credit card" do
credit_card = Factory :credit_card, :user => Factory(:user)
gateway.save_credit_card credit_card
credit_card.authorize_id.should be_present
end
it "should return true for a successful response" do
credit_card = Factory :credit_card, :user => Factory(:user)
gateway.save_credit_card(credit_card).should be_true
end
it "should mark the card as having a validated card code" do
card = Factory :credit_card, :card_code_validated => false
gateway.save_credit_card card
card.should be_card_code_validated
end
end
# etc etc etc etc
end
end
describe Payment::AuthorizeNetCim::FakeGateway do
def gateway
@gateway ||= Payment::AuthorizeNetCim::FakeGateway.new
end
it_should_behave_like 'Authorize.net CIM gateway'
# some extra custom examples
end
I prefer this to requiring an instance variable, because you get built in
error-handling for free. If you don't implement the factory method, you get
"undefined method: gateway" rather than the less obvious undefined method on
NilClass error.
Also, your :locals => { :entry => Entry.new } syntax is going to be no good
because you'll only have one instance of Entry that gets reused across
examples. No bueno. You'd have to do
:locals => lambda { { :entry => Entry.new } }
and now it's just getting ugly.
If you think defining methods is too heavy (which I wouldn't agree with, but
okay) then maybe use the let method?
describe Entry do
before do
let(:entry) { Entry.new )
end
it_should_behave_like "an_entry"
end
How's that look?
