Testing model interactor - update attribute RAILS RSpec

Question

how to write a Rspec test for update string attribute? I have attribute: "status" and array for that = ['First','Second'] - model Post

it "update status attribute" do expect(@result).to change(Post, :status) end

is it correct?

My interactor:

class User::Post::RequestVerification <  ActiveInteraction::Base

  object :user

  string :status, default: nil
  integer :id, default: nil

  validate :status

  def execute
    update_status!
  end

  def post
    @post ||= post.find(id)
  end

  def update_status!
    @post.update_atrributes!(
        status: ['First', 'Second']
    )
  end

  def status
    errors.add(:base, 'error')
  end
end

My RspecTest:

require 'rails_helper'

describe User::Post::RequestVerification do

  before do
    @result = User::Post::RequestVerification.run(new_params[:post])
  end

  let!(:user) {Post.new}
  let!(:user) { User.create }
  let!(:new_params) do
    {
        post: {

            status: 'First'

        }
    }
  end


  it "should update status" do
    expect(@result).to change(Post, :status)
  end

    end

I want to write a test to update one attribute.

Looks like the syntax of change is different. There is similar question with the similar error you mention. I won't copy the answer while I can refer you there.

expected #count to have changed by 1, but was not given a block

Also, looks like you need to chain change with by or from(..).to(..)

Take a look at the documentation https://www.relishapp.com/rspec/rspec-expectations/v/2-0/docs/matchers/expect-change
