Question

我有测试代码如下，为什么“test”应该创建“do”总是失败????

  # called before every single test
  def setup
    logger.debug '2'
    @new_user = User.create(:email                 => 'shrimpy@email.com',
                            :password              => 'secret',
                            :password_confirmation => 'secret')
    logger.debug "==========> #{@new_user.id}"
  end

  # called after every single test
  def teardown
    @new_user.delete
  end



  test "should get create" do
    logger.debug '1'
    get :create, :email => "shrimpy@email.com", :password => "secret"
    assert_response :success  # <------why it always failed here?
    assert_redirected_to user_path(@new_user)
  end

控制台输出：完成时间为3.834383秒。

  1) Failure:
test_should_get_create(SessionsControllerTest) [test/functional/sessions_controller_test.rb:24]:

这是我正在测试的功能：

 def create
    if user = User.authenticate(params[:email], params[:password])
        session[:user_id] = user.id
        redirect_to user_path(user), :notice => 'You have successfully login'
    else
        redirect_to login_url, :alert => "Invalid email/password combination"
    end
  end

由于响应不成功，因此响应是重定向。

理解这一点需要对HTTP有所了解，并对assert_response :success和redirect_to的作用有所了解。所有assert_response :success正在测试的是HTTP响应代码，它正在测试它是否是成功代码。将页面渲染回浏览器时，您会获得成功代码。当您重定向不获取成功代码时，您会获得重定向代码。

因此，如果您想检查可以使用assert_response :redirect的回复 - 尽管当您已经拥有assert_redirected_to

时这是多余的
