是否有rspec帮助来测试更新验证？

Question

我使用下面的验证

“validates_presense_of：列：上=>：更新”

是否存在被RSpec的测试上方的帮手？

Answer 1

发现这一点，这正是我想要的

Answer 2

也许：

describe ThingsController, "#update" do 
    context "for a thing" do 
    before do 
     get :update, :id => 1 
    end 
    it { should validate_presence_of :your_column_name } 
    end 
end
