rspec 参数测试失败

Question

我是 Rails 新手，我正在尝试为控制器方法创建编写规范测试，但我不知道如何传递参数用户来获取方法。 这是项目控制器

  def create
      @project = Project.new(project_params)
      @project.creator = current_user
      byebug
      if params[:project][:users].any?
        byebug
        params[:project][:users].reject!(&:empty?)
        @project.enrolled_user = User.find( params[:project][:users])
      end
    byebug
      authorize @project
      respond_to do |format|
        if @project.save
          format.html { redirect_to @project, notice: 'Project was successfully 
           created.'}
          format.json { render :show, status: :created, location: @project}
        else
          format.html { render :new}
          format.json { render json: @project.errors, status: :unprocessable_entity}
        end
      end
    end

project_spec.rb

  context "post create" do
  it "creates a new project" do
    get :new
    byebug
   
    post :create,params: { user: user.id }
    byebug
    

    expect(project1.creator).to eq(user)
    expect(enrolled_user.user_id).to eq(user1.id)
    expect(response).to be_successful
  end
end

终端的创建方法

 1) ProjectsController post create creates a new project
 Failure/Error: if params[:project][:users].any?
 
 NoMethodError:
   undefined method `[]' for nil:NilClass
 # ./app/controllers/projects_controller.rb:38:in `create'
 # ./spec/requests/project_spec.rb:49:in `block (3 levels) in <main>'

您确实需要系统测试而不是控制器测试来满足测试此处描述的功能的要求。所以 Rspec 与 Capybara 结合将允许你做这样的事情

所以使用rails g rspec:system project
并进行诸如有关

  it "Can create a project" do
    administrator_sign_in #some system test helper that creates a user and logs a user in if needed, there are plenty of examples on how to do helpers like this.
    visit '/admin/projects'
    click_link "New" 
    #save_and_open_page #Uncomment this if you want to see what your form fields are, unstyled, can be very useful when trying to see what to fill in and what button and links to press and click
    fill_in "Name", with: "New project"
    fill_in "Other project fields", with: "Some Data"
    page.check("Name of a boolean field") #check a checkbox
    click_button("Create Project")
    project = Project.find_by name: "New project"
    expect(current_path).to eq("/admin/projects/#{project.id}")
    expect(page).to have_content("Project was successfully created")
    expect(project.name_of_boolean_field).to be true
  end
