如何在不提出請求的情況下測試redirect_to

Question

我想測試一下application_controller的私有方法redirect_to的正確路徑。下面是我試圖做的：

describe 'application is complete' do 
    it 'redirects to the mortgage application show page' do 
     controller.send(:load_mortgage_application) 
     expects(controller).to receive(:redirect_to).with(mortgage_application_path(controller.locale, mortgage_application)) 
    end 
    end 

，但我得到的錯誤：

RuntimeError: 
ActionController::RackDelegation#status= delegated to @_response.status=, but @_response is nil: ... 

如何測試，而無需迴應？

//這工作：

it 'redirects to the mortgage application show page' do 
     controller.expects(:redirect_to).with(mortgage_application_path(controller.locale, mortgage_application)) 
     controller.send(:load_mortgage_application) 
    end

首先，我會假設你需要一個控制器規格範圍內，這樣你就可以，例如，使用get：load_mortgage_application。在這一點上，你可以這樣做：

response.should redirect_to '/scorecard' 

或較新的語法：

expect(response).to redirect_to '/scorecard'
