Testing Rails controllers with RSpec - how to check: current_account.projects
I am using Rspec and Rails 3 for testing. I have tested my models and helpers, but I am lost on how to start testing controllers. Almost all of my data in my controller actions is pulled using something like these examples:
@services = current_account.services
@projects = current_person.projects
@projects = current_account.projects.active
# this is really @projects = current_person.account.projects.active)
I can't seem to find examples of how to test the data that is pulled this way. All examples I have found are not account or person specific. Can someone point me to an article on how to mock or stub out this type of convention? Is this a sign that this whole approach is wrong? Below I have included the entire sample controller.
Any help would be greatly appreciated.
Thanks David

if @service.destroy
flash[:notice] = "The service was successfully deleted."
else
flash[:warning] = @service.errors.full_messages.inject("") { |acc, message| acc += message }
end
respond_with(@service)
end
end
------ UPDATE
Thanks to Xaid's solution, I was able to get the solution:
context "logged_in" do
before(:each) do
@current_account = Factory.create(:account)
controller.stub!(:current_account).and_return(@current_account)
@services = FactoryGirl.create_list(:service, 10, :account => @current_account)
@services << @current_account.services.first
@current_account.services.stub!(:all).and_return(@services)
end
# INDEX
describe "GET services" do
before(:each) do
get :index
end
it "should set @services when accessing GET /index" do
assigns[:services].should == @services
end
it "should respond with success" do
response.should be_success
end
end
end

Can't you use something like this to check the "index" action
describe "GET 'index'" do
before(:each) do
@user = FactoryGirl.create(:user)
controller.stub!(:current_user).and_return(@user)
@services = FactoryGirl.create_list(:service, 10, :user => @user)
@user.services.stub!(:all).and_return(@services)
end
it "should return a list of services" do
get :index
assigns(:services).should == @services
end
end
If I understood your question correctly, you would have to stub current_user.services (or projects) and force it to return some known value (generated by FactoryGirl in my example) and check that against the value stored in your action (e.g. @services in your action "index").
