BDD 测试驱动

1. 数据构建

gem 'factory_girl' gem 'factory_girl_rails'

• spec/factories/apply_records.rb

    FactoryGirl.define do
      factory :apply_record, :class => 'ApplyRecord' do
        resume_id 1
        job_id 2
        user_id 2
        end_at "2016-05-18 18:04:53"
        resume_status "MyString"
        recieve_at "2016-05-18 18:04:53"
        view_at "2016-05-18 18:04:53"
      end
  
      factory :apply_record2, :class => 'ApplyRecord' do
        resume_id 1
        job_id 3
        user_id 2
        end_at "2016-05-18 18:04:53"
        resume_status "MyString"
        recieve_at "2016-05-18 18:04:53"
        view_at "2016-05-18 18:04:53"
      end
    end
  

• create 方法，创建模拟数据

    it "return if user has applied job" do
      @user = create(:user)
      @job = create(:job)
      @apply_record = create(:apply_record, user_id: @user.id, job_id: @job.id)
  
      res = ApplyRecord.is_applied(@user.id,  @job.id)
      res2 = ApplyRecord.is_applied(@user.id,  nil)
  
      expect(res).to eq(true)
      expect(res2).to eq(false)
    end
  

2. Model 测试

• 测试数据库合法性验证是否生效

it 'invalid with reduplication show_name ' do
  user = create(:user, show_name: "张三")
  user2 = build(:user, show_name: "张三")
  expect(user2).to_not be_valid
end

• 测试 Model 方法

  • model方法

    # 获得剩余发布时间
    def self.time_left jid
      job = Job.find jid
    
      if job.end_at && job.end_at > Time.now
        return ((job.end_at + 1.hour - Time.now)/1.day).to_i
      else
        return 0
      end
    end
    

  • 模拟数据

   job = create :job, :hospital_id => @hospital1.id, :operate_at => Time.now - 5.days
  

  • spec 文件中

    it "test time_left jid" do
      job = create :job
    
      res = Job.time_left job.id
      expect(res).to eq(60)
    end
    

3. Controller 测试

• 测试连通性

  before :each do
    @user = create(:user)
    @user.add_role :gold
    login_with @user
    request.env['devise.mapping'] = Devise.mappings[:user]
  end
  
  describe "GET page " do
    before :each do
      @hospital = create(:hospital)
      @employer = create(:employer, hospital_id: @hospital.id, user_id: @user.id)
      @job = create(:job, hospital_id: @hospital.id)
    end
  
    it "index returns http success" do
      get :index
      expect(response).to have_http_status(:success)
    end
  
    it "show returns http success" do
      get :show, id: @job.id
      expect(response).to have_http_status(:success)
    end
  end
  

• 测试 Action

  describe 'DELETE #destroy' do
      it 'delete http success' do
        expect do
        expect{
          delete :destroy, id: @user.id
        }.to change(Resume,:count).by(-1)
        end
      end
  
      it 'redirects to users#show' do
        expect do
        delete :destroy, id: @user
        expect(response).to redirect_to new_user_session_path
        end
      end
  end
