ruby-on-rails - 为什么 rails minitest 测试用例失败

Question

我的 posts_controller_Test.rb 文件:

# test/controllers/posts_controller_test.rb
require 'test_helper'

class PostControllerTest < ActionController::TestCase
    def setup
       @post = Post.new
    end

    test 'should get index' do
        get :index
        assert_response :success
        assert_not_nil assigns(:posts)
    end
end

我的 post_controller 文件

class PostsController < ActionController::Base
    before_action :authenticate_user!

    def index
        @post = current_user.posts.paginate(page: params[:page], per_page: 5)
        respond_to do |format|
            format.html
            format.json { render json: @post }
        end
    end

    def new
        @post = Post.new
    end

    def create
        @post = current_user.posts.build(post_param)
        if @post.save
            redirect_to action: 'index'
        else
            render 'new'
    end
end

为什么我的测试用例 失败了？是因为我有 authenticate_user! 条件吗？我也有 .yml 文件并尝试用它进行测试但是在用 .yml 数据初始化后我得到了 RuntimeError: @controller is nil: make sure you set它在您的测试设置方法中。

yml文件

one:
 data 2
 value: 3
 user_id: 1
 name: 'test'

.yml 拥有我在

中需要的一切

params.require(:post).permit(:data, :value, :name) and obvious `user` for foreign key reference

建议继承ApplicationController后

得到这个新错误:

 NameError: uninitialized constant ApplicationController::Base

 app/controllers/posts_controller.rb:3:in `<top (required)>'
    app/controllers/posts_controller.rb:3:in `<top (required)>'

这是我的第 3 行:

class PostsController < ApplicationController::Base

class PostsController < ApplicationController

明白了:

  NoMethodError: undefined method `authenticate!' for nil:NilClass

错误是因为您从错误的类继承了 Controller 。改为从 ApplicationController 继承:

class PostsController < ApplicationController
  ...
end
