Testing RSpec
1

I am actually a newbie in Ruby rails nd Rspec… So it could be something
basic… Plz helpp

This is my rspec test code::

describe “GET new” do
it “assigns a new kase as @kase” do
get :new
assigns(:kase).should be_a_new(Kase)
end
end

Its failing saying:

KasesController GET new assigns a new kase as @kase
Failure/Error: assigns(:kase).should be_a_new(Kase)
expected nil to be a new Kase(id: integer, name: string,
description: text, item_loc_id: integer, created_at: datetime,
updated_at: datetime, previous_visit_id_cache: integer)
# ./spec/controllers/kases_controller_spec.rb:37
