I have the following problem

Failures:

1) QuestionsController POST #create with valid attributes saves the question in the database

Failure/Error: post :create,    question: attributes_for(:question)

ArgumentError:
  unknown keyword: question
# ./spec/controllers/questions_controller_spec.rb:68:in `block (4 levels) in <top (required)>'

2) QuestionsController POST #create with valid attributes redirect to show view

Failure/Error: post :create,   question: attributes_for(:question)

ArgumentError:
  unknown keyword: question
# ./spec/controllers/questions_controller_spec.rb:73:in `block (4 levels) in <top (required)>'

Finished in 0.46803 seconds (files took 7.17 seconds to load) 10 examples, 2 failures

Failed examples:

rspec ./spec/controllers/questions_controller_spec.rb:66 # QuestionsController POST #create with valid attributes saves the question in the database
rspec ./spec/controllers/questions_controller_spec.rb:72 # QuestionsController POST #create with valid attributes redirect to show view

here is the code of my controller

class QuestionsController < ApplicationController

  before_action :load_question, only: [:show, :edit]
  def index
    @questions = Question.all
  end

  def show
  end  

  def new
    @question = Question.new
  end

  def edit
  end

  private

  def load_question
    @question = Question.find(params[:id])
  end

  def create
    @question = Question.create(question_params)
    redirect_to @question
  end

  def question_params
    params.require(:question).permit(:title, :body)
  end

end

And here's the spec question_controller_spec.rb

require 'rails_helper'

RSpec.describe QuestionsController, type: :controller do
  let(:question) {FactoryGirl.create(:question)}

  describe "GET #index" do
    let(:questions) {FactoryGirl.create_list(:question, 2)}

    before do 
      #@questions = FactoryGirl.create_list(:question, 2) #в фабрике создаем вопросы
      get :index #вызываем экшн index
    end

    it 'populates an array ot all questions'  do #должен заполнить в массив все вопросы которые вводятся 
      expect(assigns(:questions)).to match_array(questions) #проверяем в переменой questions присутствует массив из question1 и 2
    end

    it 'renders index view' do #должен отрендерит экшн view
      expect(response).to render_template :index #ожидает ,что ответ от контроллера совпадает с нашим экшном index
    end
  end

  describe "GET #show" do
    #let(:question) {FactoryGirl.create(:question)}let(:question) {FactoryGirl.create(:question)}#создаем вопрос
    before do 
      get :show, params: {id: question.id}
    end
    it 'assings the requested question to question' do #должен установливать рапрошенный вопрос
      #вызиваем экшн show с параметром id ,то есть соответствующий вопрос
      expect(assigns(:question)).to eq question
    end

    it 'renders show view' do
      expect(response).to render_template :show
    end
  end

  describe "GET #new" do
    before do 
      get :new
    end
    it 'assingns a New Question to @question' do #создает новый вопрос
      expect(assigns(:question)).to be_a_new(Question)
    end

    it 'renders new views' do
      expect(response).to render_template :new 
    end
  end

  describe "GET #edit" do
    #let(:question) {FactoryGirl.create(:question)}
    before do
      get :edit, params: {id: question.id}
    end
    it 'assings the requested question to question' do
      expect(assigns(:question)).to eq question
    end
    it 'render new view' do
      expect(response).to render_template :edit
    end 
  end

  describe "POST #create" do
    context "with valid attributes" do
      let(:question) {create{:question}}
      it 'saves the question in the database' do #должен сохранить вопрос в БД, если оно валидний
        old_count = Question.count
        post :create,    question: attributes_for(:question) 
        #expect { post :create, question: FactoryGirl.attributes_for(:question) } .to change(Question, :count).by(1) 
        expect(Question.count).to eq (old_count + 1) # таким способом проверяется ,что добавился вопрос в БД,то есть количество возростло на 1
      end 
      it 'redirect to show view' do
        post :create,   question: attributes_for(:question) 
        expect(response).to redirect_to question_path(assigns(:question))
      end
    end
  end 
end

I can not find where is my error

There are also routes

C:\Prom\qna>rake routes
       Prefix Verb   URI Pattern                   Controller#Action
    questions GET    /questions(.:format)          questions#index
              POST   /questions(.:format)          questions#create
 new_question GET    /questions/new(.:format)      questions#new
edit_question GET    /questions/:id/edit(.:format) questions#edit
     question GET    /questions/:id(.:format)      questions#show
              PATCH  /questions/:id(.:format)      questions#update
              PUT    /questions/:id(.:format)      questions#update
              DELETE /questions/:id(.:format)      questions#destroy

You should state the problem right. Your problem is not the record is not created, but that test code fails itself. If you use Google, the first answer will tell you that according to standards you need to place all your parameters in params hash. So you should use

post :create, :params => { :question => attributes_for(question) }
