如何測試這個==> rspec的軌道+

Question

我們都知道，我們在任何基本控制器

def create 
    if @product.save 
     flash[:notice] = 'Product was successfully created.' 
     redirect_to(products_path) 
    else 
     flash[:notice] = "Data not saved try again" 
     render :action => "new" 
    end 
end 

我們如何使用測試這部分代碼的創建行動有這樣的代碼rspec的

任何建議都非常受歡迎。

PS我在RSpec的天真，所以請介意我問這個問題，如果這個問題的答案是簡單的該死:)

Answer 1

的remarkable-rails gem增加了一些匹配器來，你可以使用測試通知，重定向rspec的，和& c。這（未經測試）product_controller_spec.rb說明了如何使用remarkable_rails的匹配來測試你的代碼片段：

describe ProductController do 

    describe "create" do 

    before(:each) do 
     @product = products(:window_cleaner) 
    end 

    it "should create a product" do 
     @product.should_receive(:save).and_return(true) 
     post :create 
     should set_the_flash :notice, 
          :to => 'Production was successfully created.' 
     should redirect_to products_path 
    end 

    it "should handle failure to create a product" do 
     @product.should_receive(:save).and_return(false) 
     post :create 
     should set_the_flash :notice, :to => 'Data not saved try again.' 
     should render_template :action => 'new' 
    end 

    end 

end 

顯着護欄提供的render_template，set_the_flash和redirect_to的上面使用的匹配。
