我尝试使用minitest-rails并结合以下技术来测试 Controller 问题:
http://ridingtheclutch.com/post/55701769414/testing-controller-concerns-in-rails。
Anonymous controller in Minitest w/ Rails
我得到“没有路线匹配错误”:
ActionController::UrlGenerationError:没有路由与{:action =>“index”,:controller =>“fake”}匹配
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
最佳答案
对于OP来说可能为时已晚,但我是通过以下方式完成的:
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,但是实际上这使我的所有涉及路由访问的测试都陷入了困惑,就像
Rails.application.routes.draw
一样,我正在重写所有测试路由并只保留了solr_search_params_fake#index
路由。不知道如何添加而不是重写...。是否将解决方案直接添加到具有
config/routes.rb
条件的测试路由的if Rails.env.test?
中? (是的,这是一个糟糕的解决方案,但是如果有人发现更好的方法,我将在此保留)。
