RoR - 測試錯誤 - 預計<「categories/new」>但使用<[]>

呈現我的應用測試出現問題。現在它已經停留了很長時間，我甚至想知道爲什麼我會測試它（因爲在測試之外，它完美地工作！）？RoR - 測試錯誤 - 預計<「categories/new」>但使用<[]>

所以這裏的錯誤：

$耙測試運行選項：--seed 1855

`＃運行：

.........

在0.638134s，18.8048運行/秒，25.0731斷言/秒完成。12點運行， 16斷言，2次失誤，0失誤，0跳過

測試看起來像：

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

只給你幾個正視我迄今爲止解決我的問題所做的工作（因爲它出現之前），我已經替換了「獲取新類別表單並創建類別」的這一部分：

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

由：

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

爲測試「失敗無效類別提交結果」我取代：

post categories_path, category: {name: " "}

由：

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

而且我之前的工作對應用程序的使用（在控制器中）設置了限制：

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

有沒有人有什麼想法發生了什麼？提前致謝！

好吧，我已經得到了我的問題的答案。啞巴我，我沒有通過這些測試的用戶，顯然，通過要求用戶測試不能正確執行了。

因此，這裏的測試幫助文件的修正：

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

，爲create_categories_test：

require 'test_helper' 

class CreateCategoriesTest < ActionDispatch::IntegrationTest 

    def setup 
     @user = User.create(username: "John", email: "[email protected]", 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

爲無用的問題和困擾對不起你們！

礦是把expect之前get :index

應
get :index expect(response).to render_template(:index)
