Rspec rails - Błąd przy testach

Witam piszę testy rspec (pierwszy raz mam z tym styczność)
oto kod pliku home_controller_spec.rb

require "rails_helper"
describe HomeController do
describe "GET #index" do
it "responds successfully" do
get :index
expect(response).to be_success
it "renders index template" do
get :index
expect(response).to render_template(:index)
end
end
end
describe "GET #about" do
it "responds successfully" do
get :about
expect(response).to be_success
it "renders about template" do
get :about
expect(response).to render_template(:about)
end
end
end
describe "GET #terms" do
it "responds successfully" do
get :terms
expect(response).to be_success
it "renders terms template" do
get :terms
expect(response).to render_template(:terms)
end
end
end
end

Wywala mi taki błąd a powinno zaliczyć 6 przykładów i 0 błędów

Sformatuję to za Ciebie i wtedy zobaczysz gdzie jest błąd:

Nie, masz blok it wewnątrz bloku it, czyli dokładnie to co masz napisane w błędzie:

`it` is not available from within an example (e.g. an `it` block) or from constructs that run in the scope of an example (e.g. `before`, `let`, etc). It is only available on an example group (e.g. a `describe` or `context` block).

Nie było mnie w domu przez ten czas i dopiero teraz nad tym siadłem - czy kod powinien wyglądać właśnie tak?

require "rails_helper"
describe HomeController do
  describe "GET #index" do
    it "responds successfully" do
      get :index
      expect(response).to be_success
    end
  describe "GET #index" do
      it "renders index template" do
        get :index
        expect(response).to render_template(:index)
      end
    end
  end

  describe "GET #about" do
    it "responds successfully" do
      get :about
      expect(response).to be_success
  end
  describe "GET #about" do
      it "renders about template" do
        get :about
        expect(response).to render_template(:about)
      end
    end
  end

  describe "GET #terms" do
    it "responds successfully" do
      get :terms
      expect(response).to be_success
    end
    describe "GET #terms" do
      it "renders terms template" do
        get :terms
        expect(response).to render_template(:terms)
      end
    end
  end
end

(Proszę skasuj mojego posta wyżej źle sformatowałem treść)

Po co zagnieżdżasz/duplikujesz describe? Wystarczy raz i objąć wszystkie testy. Ten kod, który podałeś też nie wygląda na poprawny.

Porady:

• włącz sobie autoformatowanie w edytorze
• odpal linter
• podświetlaj sobie bloki i/lub nierówno podomykane bloki

By Cię już nie męczyć to poprawnie jest tak:

require 'rails_helper'

describe HomeController do
  describe 'GET #index' do
    it 'responds successfully' do
      get :index
      expect(response).to be_success
    end

    it 'renders index template' do
      get :index
      expect(response).to render_template(:index)
    end
  end

  describe 'GET #about' do
    it 'responds successfully' do
      get :about
      expect(response).to be_success
    end

    it 'renders about template' do
      get :about
      expect(response).to render_template(:about)
    end
  end

  describe 'GET #terms' do
    it 'responds successfully' do
      get :terms
      expect(response).to be_success
    end

    it 'renders terms template' do
      get :terms
      expect(response).to render_template(:terms)
    end
  end
end

Ale serio, weź sobie jakiś tutorial i/lub książkę i poczytaj. Oprócz tego naucz się samej składni Rubiego oraz angielskiego, bo to pomaga zrozumieć treść błędów.

Masz jeszcze bbatsov's style buide oraz linter (RuboCop), jak będziesz używał tych narzędzi to Twój kod będzie zdecydowanie łatwiejszy do czytania.
