Question

应用/控制器/ categories_controller.rb：

class CategoriesController < ApplicationController
    before_action :set_category, only: [:show, :edit, :update, :destroy]
    before_action :authenticate_user!, except: [:index, :show]

    # GET /categories
    # GET /categories.json
    def index
        @categories = Category.all
    end

    # GET /categories/1
    # GET /categories/1.json
    def show
        if session[:cart] then
            @cart = session[:cart]
        else
            @cart = {}
        end
    end

    # GET /categories/new
    def new
        if current_user.admin?
            @category = Category.new
        end
    end

    # GET /categories/1/edit
    def edit
        if current_user.admin?
        end
    end

    # POST /categories
    # POST /categories.json
    def create
        if current_user.admin?
            @category = Category.new(category_params)

            respond_to do |format|
                if @category.save
                    format.html { redirect_to @category, notice: 'Category was successfully created.' }
                    format.json { render :show, status: :created, location: @category }
                else
                    format.html { render :new }
                    format.json { render json: @category.errors, status: :unprocessable_entity }
                end
            end
        end
    end

    # PATCH/PUT /categories/1
    # PATCH/PUT /categories/1.json
    def update
        if current_user.admin?
            respond_to do |format|
                if @category.update(category_params)
                    format.html { redirect_to @category, notice: 'Category was successfully updated.' }
                    format.json { render :show, status: :ok, location: @category }
                else
                    format.html { render :edit }
                    format.json { render json: @category.errors, status: :unprocessable_entity }
                end
            end
        end
    end

    # DELETE /categories/1
    # DELETE /categories/1.json
    def destroy
        if current_user.admin?
            @category.destroy
            respond_to do |format|
                format.html { redirect_to categories_url, notice: 'Category was successfully destroyed.' }
                format.json { head :no_content }
            end
        end
    end

    private
        # Use callbacks to share common setup or constraints between actions.
        def set_category
            @category = Category.find(params[:id])
        end

        # Never trust parameters from the scary internet, only allow the white list through.
        def category_params
            params.require(:category).permit(:name, :desc)
        end
end

在上面的控制器中，我通过检查if current_user.admin?阻止标准用户创建，更新或销毁类别。但它在测试中引起了一些问题。

测试/控制器/ categories_controller.rb：

require 'test_helper'

class CategoriesControllerTest < ActionController::TestCase
  setup do
    @category = categories(:one)
  end

  test "should get index" do
    get :index
    assert_response :success
    assert_not_nil assigns(:categories)
  end

  test "should get new" do
    get :new
    assert_response :success
  end

  test "should create category" do
    assert_difference('Category.count') do
      post :create, category: { desc: @category.desc, name: @category.name }
    end

    assert_redirected_to category_path(assigns(:category))
  end

  test "should show category" do
    get :show, id: @category
    assert_response :success
  end

  test "should get edit" do
    get :edit, id: @category
    assert_response :success
  end

  test "should update category" do
    patch :update, id: @category, category: { desc: @category.desc, name: @category.name }
    assert_redirected_to category_path(assigns(:category))
  end

  test "should destroy category" do
    assert_difference('Category.count', -1) do
      delete :destroy, id: @category
    end

    assert_redirected_to categories_path
  end
end

由于限制，与create，update或destroy相关的测试失败。我想我需要创建一个管理员用户并登录测试设置。但我不知道该怎么做。

我正在使用Devise gem作为应用的用户部分。

我正在使用rake test:functionals运行我的测试。如何在我的测试中模拟用户创建和登录？

您可以使用灯具在测试数据库中创建管理员用户（您可能已经拥有test/fixtures/users.yml文件），并使用设计Test helpers来登录：

sign_in :user, users(:admin)

如果您的用户可以确认，请记住设置confirmed_at日期。
