Using FactoryGirl for a controller test

I want to test my Users#show controller. How can I use FactoryGirl to create test data to be passed into my controller?

In "spec/controllers/users_controller_spec.rb":

describe UsersController do
    describe "GET #show" do
        it "assigns the requested user to @user" do
            user = Factory(:user) # How do I do this using FactoryGirl?
            get :show, id: user
            assigns(:user).should eq(user)
        end
   end
end

In "spec/factories/users.rb" 

require 'faker'

FactoryGirl.define do 
    factory :user do
        email { Faker::Internet.email }
    end

    # Replace email with nil. Apparently all other attributes defer to the 
    # original :user factory.
    factory :invalid_user do
        email nil
    end
end

To wrap things up:

Use create(:user) or build(:user) as shown in latest docs instead of Factory(:user).

build(:user) does not save the object to database therefore you will probably have to stub controller's queries. It's faster though.

To pass the id of not persisted user you'll have to do get :show, id: user.id instead of get :show, id: user
