Undefined method 'subject' NoMethodError Ruby on Rails, Michael Hartl Tutorial

Question

currently I'm stuck on an error that has been plaguing me for quite some time. Any help would be greatly appreciated.

Explanation : I've tried to run 'bundle exec rspec spec/' command in my console to test whether all the scripts are working however I'm greeted with the error "undefined method 'subject' for main:object (NoMethodError)

Code for spec/requests/static_pages.rb file

     require 'spec_helper

     describe "Static pages" do

    describe "Home page" do
       before {visit root_path}
      it "should have the content 'Sample App'" do
        expect(page).to have_content('Sample App')
    end

    it "should have the title 'Home'" do
      expect(page).to have_title("Home")
    end
  end

  describe "Help page" do
      before {visit help_path}
    it "should have the content 'Help'" do
      expect(page).to have_content('Help')
    end

    it "should have the title 'Help'" do
      expect(page).to have_title("Help")
    end
  end

  describe "About page" do
    before {visit about_path}
    it "should have the content 'About Us'" do
      expect(page).to have_content('About Us')
    end

    it "should have the title 'About Us'" do
      expect(page).to have_title("About Us")
    end
  end

  describe "Contact Page" do    
    before {visit contact_path}
    it "should have the content 'Contact'" do
        expect(page).to have_content('Contact')
    end
    it "should have the title 'Contact'" do
        expect(page).to have_title("Contact")
    end
  end
end

and for spec/models/user_spec.rb

require 'spec_helper'

describe User do
  before do
    @user = User.new(name: "Example User", email: "[email protected]", password: "foobar", password_confimation: "foobar")
  end

  subject { @user }

  it { should respond_to(:name) }
  it { should respond_to(:email) }
  it { should respond_to(:password_digest)}
  it { should respond_tp(:password)}
  it { should respond_to(:password_confimation)}
  it { should respond_to(:authenticate)}


  it { should be_valid }

  describe "with a password that's too short" do
    before { @user.password = @user.password_confirmation = "a" * 5 }
    it { should be_invalid }
  end

  describe "return value of authenticate method" do
    before { @user.save }
    let(:found_user) { User.find_by(email: @user.email) }

    describe "with valid password" do
      it { should eq found_user.authenticate(@user.password) }
    end

    describe "with invalid password" do
      let(:user_for_invalid_password) { found_user.authenticate("invalid") }

      it { should_not eq user_for_invalid_password }
      specify { expect(user_for_invalid_password).to be_false }
    end
  end

code for specified file 'generic.rb'

'subject {page}

describe "Home page" do
    before {visit root_path}
    it {should have_content ('Sample App')}
    it {should have_title(full_title(''))}
    it {should_not have_title('| Home')}
end'

Since you are a beginner I like to point you to this article: nofail.de/2013/10/debugging-rails-applications-in-development — phoet
Hi, phoet I'm new on this forum so I'm still trying to figure out things. Thank you for the article link. BriotStatse the full error message : spec/support/generic.rb:1:in '(top (required))':undefined method 'subject' for main:object (noMethodError) — Neal

You need to move your subject declaration inside describe block:

describe "Home page" do
    subject {page}
    before {visit root_path}
    it {should have_content ('Sample App')}
    it {should have_title(full_title(''))}
    it {should_not have_title('| Home')}
end
