This document provides an overview and agenda for testing with RSpec 3. It discusses RSpec expectations and matchers, mocks vs stubs, model specs, controller specs, using FactoryGirl for test data, API testing best practices, and references for further reading on RSpec 3. The overview covers setting up RSpec, expectations, mocking, testing models, controllers, factories, shared examples, API testing, and JSON helpers.

assigns, flash, session

15. Factories vs Fixtures

16. Factories
● YML files loaded on start
● Bypass ActiveRecord
● Easy to generate from Real Data

17. FactoryGirl

18. FactoryGirl - instantiation options
❖ create: saves object to the database, and
saves any associated objects too
❖ build: builds object in memory only, but still
saves any associated objects to the
database
❖ build_stubbed: builds object in memory
only, as well as any associated objects

19. Shared Examples

20. API Testing - best practices
