[英]How to test this ==> rspec + rails
我們都知道在任何基本控制器的create動作中都有此代碼
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rspec測試這部分代碼
任何建議都是最歡迎的。
PS:我對rspec天真,所以請介意我問這個問題,如果答案很簡單:)
非凡的Rails gem為rspec添加了一些匹配器,可用於測試通知,重定向和&c。 這個(未經測試的)product_controller_spec.rb顯示了如何使用非凡的_rails匹配器來測試您的代碼片段:
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
出色的軌道提供了上面使用的render_template,set_the_flash和redirect_to匹配器。
