HI All,
I have a controller with the following in it:
def index
@purchase_requests = PurchaseRequest.find(:all)
@num_found = @purchase_requests.size
end
I want to test that @num_found is getting the number of purchase
requests.
This is what I've tried:
it "should count the number of purchase requests found" do
@purchase_requests.stub!(:size).and_return 3
@num_found.should_equal(3)
get :index
end
However, I Get This Error:
NoMethodError in 'PurchaseRequestsController Get index should count
the number of purchase requests found'
You have a nil object when you didn't expect it!
The error occurred while evaluating nil.should_equal
./spec/controllers/purchase_requests_controller_spec.rb:21:
It seems that rspec wants me to stub the instance variable. If I do
that then I don't think I'd actually be testing anything because I'd
create the stub in the test and verify that the stub I created is
there. I want to make sure that the test will fail if I delete the
line in the actual controller or change the name. Can someone show me
how to do this?
thanks in advance.
Leo
