Controller:

def search  
unless params[:data\_search].blank?  
shop\_data = params[:data\_search]  
@shops = Shop.data\_search(shop\_data).paginate(:per\_page =\>  
Settings.shops\_per\_page, :page =\> params[:page])  
else  
@shops = Shop.all.paginate(:per\_page =\> Settings.shops\_per\_page,  
:page =\> params[:page])  
end  
render :layout =\> false if request.xhr?  
end

controller.spec:

def mock\_shop(stubs={})  
@mock\_shop ||= mock\_model(Shop, stubs).as\_null\_object  
end

describe “search” do  
context “when name is ‘Test’” do  
it “should find shops” do  
@name = “Test”  
Shop.stub(:search).with(@name) { [mock\_shop] }  
get :search, :name =\> @name  
assigns(:shops).should eq([mock\_shop])  
end  
end  
end

La failure:

Failure/Error: assigns(:shops).should eq([mock\_shop])

Fai lo stub di .search ma nel controller entri in questa condizione

> @shops = Shop.all.paginate(:per\_page =\> Settings.shops\_per\_page,  
> :page =\> params[:page])

Quindi dovresti fare lo stub di all.pagiante per ottenere il risultato  
che desideri.  
Se usi il mocking di rspec puoi usare stub\_chain. Prova con qualcosa  
tipo Shop.stub\_chain(:all, :paginate).and\_return([mock\_shop])

Il problema era semplicemente nel parametro sbagliato, deve essere get  
:search, :data\_search =\> … e non :name =\> …  
Adesso funziona anche senza fare lo stub di paginate.
