Minitest - 测试控制器问题

Question

我尝试使用 minitest-rails 并结合这些技术来测试我的控制器问题：

Anonymous controller in Minitest w/ Rails

我得到“没有路线匹配错误”： ActionController::UrlGenerationError: 没有路由匹配 {:action=>"index", :controller=>"fake"}

require "test_helper"
require "warden_mock"

class FakeController < ApplicationController
  attr_accessor :request

  def initialize(method_name=nil, &method_body)
    include MyConcern # method redirect_to_404 placed here

    @request = OpenStruct.new # mockup request
    @request.env = {}
    @request.env['warden'] = WardenMock.new # mockup warden

    if method_name and block_given? # dynamically define action for concern methods testing
      self.class.send(:define_method, method_name, method_body)
      test_routes = Proc.new do
        resources :fake
      end
      Rails.application.routes.eval_block(test_routes)
    end
  end
end


describe FakeController do # just very simple test
  context "just redirect_to_404" do
    it "it must redirect to /404" do
      @controller = FakeController.new(:index) { redirect_to_404 }
      get :index
      assert_redirected_to '/404'
    end
  end
end

我有 rails 4.1.5 和 minitest 5.4.0

Answer 1

对于 OP 来说可能为时已晚，但我已经这样做了：

require 'test_helper'

class SolrSearchParamsFakeController < ApplicationController
  include SolrSearchParams # this is my controller's concern to test

  def index
    # The concern modify some of the parameters, so I'm saving them in a
    # variable for future test inspection, so YMMV here.
    @params = params
    render nothing: true
  end
end

Rails.application.routes.draw do
  # Adding a route to the fake controller manually
  get 'index' => 'solr_search_params_fake#index'
end

class SolrSearchParamsFakeControllerTest < ActionController::TestCase
  def test_index
    get :index, search: 'asdf wert'

    # finally checking if the parameters were modified as I expect
    params = assigns(:params)
    assert_equal params[:original_search], 'asdf wert'
  end
end

更新

抱歉，但实际上这会以某种方式弄乱我所有涉及路由访问的测试，就像 Rails.application.routes.draw 一样，我正在重写所有测试路由，只留下 solr_search_params_fake#index 路由。
不知道如何添加而不是重写......修复将直接添加到 config/routes.rb 我的测试路线与 if Rails.env.test? 条件？ （是的，这是一个糟糕的解决方案，但我会把它留在这里，以防有人找到更好的方法）。
