Good day all :-)
I am getting into RSpec and am a little confused by an aspect of mocks /
mock_models in controller tests. I've gone through the online docs and the
PeepCode movies and have them slightly contradictory on this matter. I hope
you can clarify. Many thanks in advance :-)
I'm writing a system that uses the restful authentication plugin and am
writing a test for the following controller create method:
class AccountsController < ApplicationController
def create
@account = Account.new(params[:account])
if @account.save!
self.current_account = @account
redirect_back_or_default('/')
flash[:notice] = "Thanks for signing up!"
end
rescue ActiveRecord::RecordInvalid
render :action => 'new'
end
...
end
I've created the following spec test to simply ensure that the Account model
receives a call to :new, but the spec is failing as it also receives a call
to :save! and it isn't expecting it. I am using "@account =
mock_model(Account)". If i replace this with "@account = mock('account',
:null_object => true)" the test passes, but i'm not sure that's really what
i want. I'm pretty sure i need to us mock_model in this instance.
The code is below.
Also, are my use of comment blocks within the spec against the RSpec *way*.
I appreciate that this isn't using fixtures and i might use them later. I
also appreciate that i can write modules to contain these methods, but i
can't quite see the point in muddying things. Comments most welcome.
Thanks
