🏭 Simplifying Test Data with FactoryBot

FactoryBot helps you generate test data more flexibly than fixtures. Add the gem, configure, then define factories under spec/factories.

gem 'factory_bot_rails', '~> 6.0', group: :test

# spec/factories/users.rb
FactoryBot.define do
  factory :user do
    name { 'Factory User' }
    email { 'factory@example.com' }
  end
end

Use it in specs:

RSpec.describe User, type: :model do
  it 'builds a valid user' do
    user = build(:user)
    expect(user).to be_valid
  end

  it 'persists a user' do
    expect { create(:user) }.to change(User, :count).by(1)
  end
end
