Minitest 中的匿名控制器 w/Rails

Question

在从 RSpec 转换到 Minitest 时，我遇到了一个小问题，Google 没有提供任何帮助，那就是弄清楚如何做这样的事情：

describe ApplicationController do
  controller do
    def index
      render nothing: true
    end
  end

  it "should catch bad slugs" do
    get :index, slug: "bad%20slug"
    response.code.should eq("403")
  end
end

与 Minitest。有没有办法在 Minitest 内部创建这样的匿名控制器，或者是否有文档可以帮助我学习如何使用 minitest 测试控制器？

你可以这样做：

# Add at runtime an action to ApplicationController
ApplicationController.class_eval do
  def any_action
    render :nothing
  end
end

# If disable_clear_and_finalize is set to true, Rails will not clear other routes when calling again the draw method. Look at the source code at: http://apidock.com/rails/v4.0.2/ActionDispatch/Routing/RouteSet/draw
Rails.application.routes.disable_clear_and_finalize = true

# Create a new route for our new action
Rails.application.routes.draw do
  get 'any_action' => 'application#any_action'
end

# Test
class ApplicationControllerTest < ActionController::TestCase
  should 'do something' do
    get :any_action

    assert 'something'
  end
end
