Rspec param is missing or the value is empty: user

Hello i'm testing the Update action the User Controller using Rspec.

I get this error

  1) UsersController POST #update user updated
     Failure/Error: patch :update, {id: user.id }, { user_id: user.id }, user: user_params
     ActionController::ParameterMissing:
       param is missing or the value is empty: user
     # /Users/joseph/.rvm/gems/ruby-2.1.2/gems/actionpack-4.2.0/lib/action_controller/metal/strong_parameters.rb:249:in `require'
     # ./app/controllers/users_controller.rb:60:in `user_params'
     # ./app/controllers/users_controller.rb:39:in `update'

Weird thing is i used a binding.pry to test whats going on. There is a user and there are user_params. So i don't understand why i receive the above error.

Please see below for the user and user params.

here is the User controller

  def update
    if @user.update_attributes(user_params)
      flash[:success] = "Profile updated"
      redirect_to @user
    else
      render 'edit'
    end
  end

  private

  def set_user
    @user = User.find(params[:id])
  end

  def user_params
    params.require(:user).permit(
      :username,
      :email,
      :password,
      :password_confirmation,
      :avatar,
      :header_image,
      :description
