ruby-on-rails - 在 Spree Controller Decorator 上测试重写操作

Question

我在测试 Spree Controller 装饰器的覆盖操作时遇到问题，如下所示:

app/controllers/spree/checkout_controller_decorator.rb

Spree::CheckoutController.class_eval do
  def update
     do_something
     redirect_to my_other_path
  end
end

我的规范是:

spec/controllers/spree/checkout_controller_spec.rb

describe Spree::CheckoutController do
  routes { Spree::Core::Engine.routes }

  it "does something" do
    put :update
  end
end

但它从未进入我的更新定义，它正在进入 Spree 原始定义。

我尝试重现您上述提到的问题。我确实遇到了同样的问题。但是在我查看测试日志后，对我来说它在提示

过滤器链因 :ensure_checkout_allowed 呈现或重定向而停止

因为重写的 Controller 从未被执行过。它甚至在到达覆​​盖的方法之前就失败了。

这是我的规范文件的样子:规范/ Controller /checkout_controller_spec.rb

require "spec_helper"

describe Spree::CheckoutController do
  let(:order) {FactoryGirl.create(:spree_order)}

  before(:each) do
    @routes = Spree::Core::Engine.routes
    controller.stub :check_authorization => true
    controller.stub :ensure_checkout_allowed => true
    controller.stub :ensure_valid_state => true
    controller.stub :current_order => order
  end

  it "does something" do
    user = create(:spree_user)
    user.spree_roles.create(:name => "admin")
    sign_in(user)

    puts @routes.inspect
    spree_put :update, :order => {}
    assigns(:test_obj).should eql(1)
  end
end

这是我覆盖的 Controller 文件的样子:/app/controller/spree/checkout_controller_decorator.rb

Spree::CheckoutController.class_eval do
  def update
    @test_obj = 1
    render :nothing => true
  end
end

您可能需要 stub 一些 before_filters 或编写一些代码以使 before_filters 通过
