Question

我的应用测试存在问题。它现在已经存在了很长时间，我甚至想知道，为什么我要对它进行测试（因为在测试之外，它完美无缺！）??

所以这里有错误：

$ rake test   运行选项： - 选择1855

`#Running：

以0.638134s结束，18.8048次/秒，25.0731次断言/秒。 12次跑，   16个断言，2个失败，0个错误，0个跳过

测试看起来像：

require 'test_helper'

class CreateCategoriesTest < ActionDispatch::IntegrationTest

  test "get new category form and create category" do
    get new_category_path
    assert_template 'categories/new'
    assert_difference 'Category.count', 1 do
    post categories_path, params: { category: {name: "sports"}}
    follow_redirect!
    end
    assert_template 'categories/index'
    assert_match 'sports', response.body
  end

  test "invalid category submission results in failure" do
    get new_category_path
    assert_template 'categories/new'
    assert_no_difference 'Category.count' do
    post categories_path, params: { category: {name: " "}}
    end
    assert_template 'categories/new'
    assert_select 'h3.panel-title'
    assert_select 'div.panel-body'
  end
end

和控制器：

class CategoriesController < ApplicationController

  before_action :require_admin, except: [:index, :show]

  def index
    @categories = Category.paginate(page: params[:page], per_page: 5)
  end

  def new
    @category = Category.new
  end

  def create
    @category = Category.new(category_params)
    if @category.save
      flash[:success] = "La nueva categoria se creó correctamente"
      redirect_to categories_path
    else 
      render 'new'
    end
  end

  def index
     @categories = Category.paginate(page: params[:page], per_page: 5)
  end

  def show
  end

  private

  def category_params
    params.require(:category).permit(:name)
  end

  def require_admin
    if !logged_in? || logged_in? and !current_user.try(:admin?)
      flash[:danger] = "Solamente el admin puede acceder a esta seccion"
    redirect_to categories_path
    end
  end


end

为了让您了解到目前为止我为解决问题所做的工作（因为它之前出现过），我已经取代了这部分＆＃34;获取新类别表格并创建类别＆＃34;：

post_via_redirect categories_path, category: {name: "sports"}

by：

post categories_path, params: { category: {name: "sports"}}
follow_redirect!

对于＆＃34;无效的类别提交导致失败＆＃34;我替换了测试：

post categories_path, category: {name: " "}

由：

post categories_path, params: { category: {name: " "}}

并且在我对应用程序（在控制器中）的使用施加限制之前它已经起作用了：

before_action :require_admin, except: [:index, :show]
[...]
  def require_admin
    if !logged_in? || logged_in? and !current_user.try(:admin?)
      flash[:danger] = "Solamente el admin puede acceder a esta seccion"
    redirect_to categories_path
    end
  end

有没有人知道发生了什么？提前致谢！

Answer 1

好的，我已经得到了我的问题的答案。愚蠢的我，我没有通过用户进行这些测试，显然，要求用户测试无法正常执行。

所以这是测试帮助文件中的更正：

require File.expand_path('../../config/environment', __FILE__)
require 'rails/test_help'

class ActiveSupport::TestCase
  # Setup all fixtures in test/fixtures/*.yml for all tests in alphabetical order.
  fixtures :all

  # Add more helper methods to be used by all tests here...
  def sign_in_as(user, password)
    post login_path, params: { session: {email: user.email, password: password}}
  end
end

和create_categories_test：

require 'test_helper'

class CreateCategoriesTest < ActionDispatch::IntegrationTest

    def setup
        @user = User.create(username: "John", email: "john@example.com", password: "password", admin: true)
    end

  test "get new category form and create category" do
    sign_in_as(@user, "password")
    get new_category_path
    assert_template 'categories/new'
    assert_difference 'Category.count', 1 do
    post categories_path, params: { category: {name: "sports"}}
    follow_redirect!
    end
    assert_template 'categories/index'
    assert_match 'sports', response.body
  end

  test "invalid category submission results in failure" do
    sign_in_as(@user, "password")
    get new_category_path
    assert_template 'categories/new'
    assert_no_difference 'Category.count' do
    post categories_path, params: { category: {name: " "}}
    end
    assert_template 'categories/new'
    assert_select 'h3.panel-title'
    assert_select 'div.panel-body'
  end
end

对不起家伙的无用问题和困扰！

Answer 2

我在expect

之前放get :index

哪个应该是 get :index expect(response).to render_template(:index)

RoR - 测试错误 - 期待＆lt;＆＃34;类别/新＆＃34;＆gt;但使用＆lt; []＆gt;
