- Like “test driven development”
- Initially unit test focussed
- business doesn’t care about underlying implementation, just the functional results
- “executable specification” – written in spoken language
- “infrastructure as code”
- code without tests is “bad”
- Taking BDD and adapting to infrastructure development
- Tools – cucumber – write specs, execute/test specs
- cucumber-nagios
- DEMO of cucumber and cucumber-nagios
- example – continuous server builds as you update you config manager
- migration to config management. – Use BDI to test existing, test CM env with same tests to make sure it replicates
- Monitoring System : notify -> test -> repeat
- Current monitoring systems miss many things
- cucumber provides a common specification format that dev and ops can share
- removes duplication of tests
- Libraries being built of commons test (some already in cucumber nagios)
