3. tools salt – saltstack.com
configuration management and remote execution
test-kitchen – kitchen.ci
test harness tool to execute your configured code on one or more platforms in isolation
serverspec – serverspec.org
integration testing framework built on rspec
vagrant – vagrantup.com
wrapper for virtual machine configuration

4. why? ensure what we have is what we expect configuration management
variables
config files
simplifies life with multiple contributors
simplifies working w/ multiple operating systems
think more deeply about our environment
enables use in continuous integration
provides certainty

5. manual build and provision
install operating system from .iso
use package manager to install required programs from checklist
change required configuration files

6. write automation code, manually test
configuration management
make changes
provision box
verify changes
how long does testing take?

7. automated testing think about what we're testing serverspec testing
test-kitchen
continuously testing infrastructure
kitchen-ec2

8. test driven development
write test harness for feature requirements (red)
write minimal code to make test pass (green)
rewrite code for maintainability (refactor)
