Testing and deploying Rails
Ship a tested Rails app to production.
📖 Key ideas
- Rails includes Minitest; many teams use RSpec.
- Model, request and system tests cover different layers.
- Fixtures or FactoryBot create test data.
- Rails 8 uses Kamal to deploy containers to any server.
- Run bin/rails assets:precompile and migrations during deploy; watch logs after.
💡 Real-life example: Like a final rehearsal before the annual day: tests rehearse every scene, and deploy is opening night.
