How to check if a record is saved in the database using rspec with Rails 4?

How do I write a spec to check if a new record is created in the database after a successful user signup? Using rspec in Rails 4 with capybara, factorygirl, and database_cleaner gems.

I feel like this situation is common and an answer should be easy to find, but I haven't been able to find one here or via google.

You probably want the change matcher

You will do something like:

expect { 
  post :create, :user => {:user => :attributes }
}.to change { User.count }

or

expect { 
  post :create, :user => {:user => :attributes }
}.to change(User, :count)

This code says:

expect that running this first block of code to change the value I get when I run that block of code

and is functionally equivalent to writing:

before_count = User.count
post :create, :user => {:user => :attributes }
expect(User.count).not_to eq(before_count)

As you are using factorygirl, you can used factorygirl to create test data

FactoryGirl.define do
 factory :user do
  sequence(:name) { |n| "user #{n}" }
  sequence(:email) { |n| "sampleuser+#{n}@sampleuser.com" }
  password '123456789'
end end

you can used 'FactoryGirl.create(:user)' whenever you want a user record.

To test you can write spec like this

expect{
      post :create, {user: FactoryGirl.attributes_for(:user)}
    }.to change(User, :count).by(1)

Since you mentioned capybara so I'm gonna assume you want a feature spec, of course you're going to need to change the details to match your application

require 'rails_helper'
feature 'Users' do # or whatever
  scenario 'creating an account' do
    visit root_path
    click_link 'Sign Up'
    fill_in 'Name', with: 'User 1'
    fill_in 'Email', with: '[email protected]'
    fill_in 'Password', with: 'password'
    expect{
      click_button 'Sign up'
    }.to change(User, :count).by(1)
  end
end
