Hi!
I'm trying to test the following (simplified) model:
class Allocation < ActiveRecord::Base
scope :in_interval, (proc do |start_of_interval, end_of_interval|
params = {:s => start_of_interval, :e => end_of_interval}
where("(starts_at > :s AND starts_at < :e) OR (ends_at > :s AND ends_at <
:e) OR (starts_at <= :s AND ends_at >= :e)", params)
end)
scope :on_day, (proc do |day|
day = day.to_time.beginning_of_day
in_interval(day, day + 1.day)
end)
# validations and other scopes...
end
I wrote a lot of specs for :in_interval - however testing :on_day is kind of
problem. I don't want to duplicate any :in_interval specs - therefore I'm
trying to stub :in_interval like this:
let(:start_of_day) { Time.zone.now.beginning_of_day }
it do
Allocation.should_receive(:in_interval).with(start_of_day, start_of_day +
1.day).and_return("result")
# working assertion - the :in_interval stub seems to get called as expected:
# Allocation.on_day(start_of_day + 3.hours)
# failing assertion:
Allocation.on_day(start_of_day + 3.hours).should == "result"
end
RSpec Output:
Failure/Error: Allocation.on_day(start_of_day + 3.hours).should == "result"
NoMethodError:
undefined method `includes_values' for "result":String
I'm using Rails 3.0.4 and RSpec 2.5 (latest versions).
Best regards,
Christoph Schiessl
