testing in production
expressionops cultureprogramming
The practice - reckless or disciplined, depending entirely on tooling - of validating changes on the live system.
As a punchline it mocks missing test environments; as a discipline (feature flags, canaries, dark launches, chaos engineering) it acknowledges that production is the only environment that tells the whole truth. The joke and the strategy are separated by observability and a rollback path.
