expect(CreatesProject).to have_received(:new).with({name: "Runway", task_string: "start something:2"})

[MunimIftikhar]

I am trying to run the controller test in the Rails application.

Controller code

Here is the code I'm trying to test (/app/controllers/projects_controller.rb):

class ProjectsController < ApplicationController
  ## START: show
  def show
    @project = Project.find(params[:id])
    respond_to do |format|
      format.html {}
      format.js { render json: @project.as_json(root: true, include: :tasks) }
    end
  end
  ## END: show

  def new
    @project = Project.new
  end

  def index
    @projects = Project.all
  end

  ## START: create
  def create
    @workflow = CreatesProject.new(
      name: params[:project][:name],
      task_string: params[:project][:tasks])
    @workflow.create
    if @workflow.success?
      redirect_to projects_path
    else
      @project = @workflow.project
      render :new
    end
  end
  ## END: create
end

Controller Test

Here is the test(/spec/controllers/projects_controller_spec):

require "rails_helper"

RSpec.describe ProjectsController, type: :controller do

  describe "create" do
    it "calls the workflow with parameters" do
      workflow = instance_spy(CreatesProject, success?: true)
      allow(CreatesProject).to receive(:new).and_return(workflow)
      post :create,
        params: {project: {name: "Runway", tasks: "start something:2"}}
      expect(CreatesProject).to have_received(:new)
        .with({name: "Runway", task_string: "start something:2"})
    end

  end

end

Error

After running the command bundle exec rspec, I'm getting the following error:

1) ProjectsController create calls the workflow with parameters
     Failure/Error:
       expect(CreatesProject).to have_received(:new)
         .with({name: "Runway", task_string: "start something:2"})
     
       (CreatesProject (class)).new({:name=>"Runway", :task_string=>"start something:2"})
           expected: 1 time with arguments: ({:name=>"Runway", :task_string=>"start something:2"})
           received: 0 times
     # ./spec/controllers/projects_controller_spec.rb:11:in `block (3 levels) in <top (required)>'

Can anyone help me with this?
