Hi everyone, RSpec newbie here. I'm looking forward to interacting
with the community as I learn more about TDD, RSpec, Rails, and...
TDD through RSpec in Rails.
Having watched the Peepcode screencasts and read a lot of
documentation, I'm trying to write my first comprehensive
applications using TDD from the ground up. I'm stuck writing a test
for my controller, though.
This application is your basic crappy social network. There are
three relevant models in play right now: User, Group, and
Membership. User and Group have :has_many relationships with each
other :through Membership; Membership, in addition to having a
user_id and a group_id, also has a column called "rank", to which I
write in either "officer" or "member" as a value.
Group also defines the following relationships just for convenience:
has_many :memberships
has_many :officers, :through => :memberships, :source
=> :user, :conditions => "rank = 'officer'"
has_many :members, :through => :memberships, :source
=> :user, :conditions => "rank = 'member'"
I'm trying to test the CREATE functionality in my Group controller.
Unfortunately, this test is not working.
it "should make the creating user an officer" do
Group.stub!(:new).and_return(mock_group(:save => true))
post :create, :group => {}
assigns[:group].should have(1).officer
end
The error message:
Mock 'Group_1008' received unexpected message :officer with (no
args)
If I understand this correctly, I am getting the error because
assigns[:group] isn't really an ActiveRecord object, just a mock,
and I guess the relationships don't carry over? If this is the
case, what's the right way to test it, assuming that a Membership
really is being created in my controller's create function?
Thanks,
O.
Hi O. The Group that you're creating is a Mock. Thus, it doesn't have
any of the methods (Eg: #officer) that a real Group has. Since
#officer hasn't been stubbed out on the mock Group, the error occurs.
As for how to spec that the relationships are being setup correctly,
can you provide the code for the Group's "new" action?
Cheers,
Nick
